Section I
Safety Precautions
WARNING
A. Arc Welding
Arc Welding can be hazardous. Protect
yourself and others from possible serious
injury or death. Keep children away.
Pacemaker wearers keep away until
consulting your doctor.
In welding, as in most jobs, exposure to certain
hazards occurs. Welding is safe when
precautions are taken. The safety information
given below is only a summary of the more
complete safety information that will be found
in the Safety Standards listed at the end of this
section. Read and follow all Safety Standards.
Have all installation, operation, maintenance
and repair work performed only by qualified
people.
B. Electric Shock
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and work
circuit is electrically live whenever the output is
on. The input power circuit and machine
internal circuits are also live when power is on.
When using mechanized wire feed, the wire,
wire reel, drive roll housing and all metal parts
touching the welding wire are electrically live.
Incorrectly installed or improperly grounded
equipment is a hazard.
1.
Do not touch live electrical parts.
2.
Wear dry, hole-free insulating gloves and
appropriate body protection.
1
3.
Disconnect input power before installing
o r s e r v i c i n g t h i s e q u i p me n t .
Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety
Standards).
4.
Properly install and ground this
equipment according to the operation
manual and national, state and local
codes.
5.
Always verify the supply ground-check
and be sure that input power cord ground
wire is properly connected to ground
terminal in disconnect box or that cord
plug is connected to a properly grounded
receptacle outlet.
6.
When making input connections, attach
proper grounding conductor first double-check connections.
7.
Frequently inspect input power cord for
damage or bare wiring. Replace cord
immediately if damaged - bare wiring can
kill.
8.
Turn off all equipment when not in use.
9.
If earth grounding of the workpiece is
required, ground it directly with a
separate cable - do not use work clamp or
work cable.
10.
Do not touch electrode if you are in
contact with the work, ground, or another
electrode from a different machine.
11.
Use only well-maintained equipment.
Repair or replace damaged parts at once.
Maintain unit according to manual.
12.
Wear a safety harness if working above
floor level.
HWP-50E Hot Wire Process
13.
Keep all panels and covers securely in
place.
2.
If inside, ventilate the area and/or use
exhaust at the arc to remove welding
fumes and gases.
14.
Clamp work cable with good metal-tometal contact to workpiece or worktable
as near the weld as practical.
3.
If ventilation is poor, use an approved airsupplied respirator.
C. Arc Rays
4.
Arc rays can burn eyes and skin; noise can
damage hearing; flying slag or sparks can injure
eyes.
Read the Material Safety Data Sheets
(MSDS) and the manufacturer's
instruction for metals, consumables,
coatings, cleaners, and degreasers.
5.
Work in a confined space only if it is well
ventilated, or while wearing an airsupplied respirator. Always have a trained
watch person nearby.
6.
Do not weld in locations near degreasing,
cleaning, or spraying operations. The heat
and rays of the arc can react with vapors
to form highly toxic and irritating gases.
7.
Do not weld on coated metals, such as
galvanized, lead or cadmium plated steel,
unless the coating is removed from the
weld area, the area is well ventilated, and
if necessary, while wearing an airsupplied respirator. The coatings and any
metals containing these elements can give
off toxic fumes if welded.
Arc rays from the welding process produce
intense visible and invisible (ultraviolet and
infrared) rays that can burn eyes and skin. Noise
from some processes can damage hearing.
Chipping, grinding and weld cooling throw off
pieces of metal or slag.
1.
Use approved ear plugs or ear muffs if
noise level is high.
2.
Use a welding helmet fitted with a proper
shade of filter to protect your face and
eyes when welding or watching.
3.
Wear approved safety glasses with side
shields.
4.
Use protective screens or barriers to
protect others from flash and glare; warn
others not to watch the arc.
5.
E. Cylinders
Cylinders can explode if damaged.
Wear protective clothing made from
durable, flame-resistant material (wool
and leather) and foot protection where
necessary.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the
welding process, be sure to treat them carefully.
D. Fumes and Gases
1.
Protect compressed gas cylinders from
excessive heat, mechanical shocks, slag,
open flames, sparks, and arcs.
2.
Install cylinders in an upright position by
securing to a stationary support or
cylinder rack to prevent falling or tipping.
Fumes and gases can be hazardous to your
health.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
1.
Keep your head out of the fumes. Do not
breathe the fumes.
2
HWP-50E Hot Wire Process
3.
Keep cylinders away from any welding or
other electrical circuits.
5.
Watch for fire, and keep a fire
extinguisher nearby.
4.
Never weld on a pressurized cylinder explosion will result.
6.
5.
Use only correct shielding gas cylinders,
regulators, hoses and fittings designed for
the specific application; maintain them
and associated parts in good condition.
Do not weld on closed containers such as
tanks, drums, or pipes, unless they are
properly prepared according to AWSF4.1
(see safety Standards).
7.
Connect work cable to the work as close
to the welding area as practical to prevent
welding current traveling long, possibly
unknown paths and causing electric shock
and fire hazards.
Wear oil-free protective garments such as
leather gloves, heavy shirt, cuffless
trousers, high shoes, and a cap.
6.
Turn face away from valve outlet when
opening cylinder valve.
7.
Keep protective cap in place over valve
except when cylinder is in use or
connected for use.
8.
8.
Read and follow instructions on
compressed gas cylinders, associated
equipment, and CGA publication P-1
listed in Safety Standards.
G. Moving Parts
F.
Moving parts, such as fans, rotors, and belts can
cut fingers and hands and catch loose clothing.
Welding
1.
Keep all doors, panels, covers, and guards
closed and securely in place.
2.
Have only qualified people remove
guards or covers for maintenance and
troubleshooting as necessary.
Welding can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up.
Sparks can fly off from the welding arc. The
flying sparks, hot workpiece, and hot equipment
can cause fires and burns. Accidental contact of
electrode to metal objects can cause sparks,
explosion, overheating, or fire. Check and be
sure the area is safe before doing any welding.
1.
Protect yourself and others from flying
sparks and hot metal.
2.
Do not weld where flying sparks can
strike flammable material.
3.
Remove all flammables within 35 ft (10.7
m) of the welding arc. If this is not
possible, tightly cover them with
approved covers.
4.

HWP-50E Hot Wire Process
Section II
Introduction
The HWP-50E consists of the following parts:
The hot wire welding process produces a high
quality weld with a high deposition rate of the
filler material. It differs from the more common
cold wire process in that the filler wire is
electrically preheated and enters the weld pool
at a temperature close to its melting point. This
prevents the wire from chilling the weld pool
and allows the filler metal to flow out across the
puddle, solidifying in a smooth, rounded bead.
Deposition rates up to 18 lb/hr (8 kg/hr) are
achievable under the right circumstances.
HWP-200E Contoured Wave Power Supply
This is a unique AC power supply in which the
AC output waveform is electronically generated
to closely simulate a sine wave form. The use
of sinusoidal AC voltage greatly improves the
flow of the hot wire into the weld pool. The AC
frequency is adjustable from 50 to 200 Hz. The
power supply is rated at 200 amps at 100% duty
cycle and the nominal output voltage is
adjustable from 2 to 15 VAC through the 9302C
control.
One of the more important benefits of the hot
wire process is the virtual elimination of
porosity from the weld deposit. Experiments
have shown that the I2R heating of the filler
wire as it approaches the weld puddle drives off
most of the volatile surface contamination.
Since hydrogen or hydrogen containing
compounds entrapped on the surface of the filler
metal are a primary cause of porosity in high
performance materials, use of the hot wire
process can be expected to remove this potential
source of difficulty.
There are two power supply models available:
HWP-200E-1-F7 is the 360/480 VAC model;
HWP-200E-1-220-F7 is the 220 VAC model.
WF-50 Wire Feed Head
The wire feed head has four gear-driven rolls
driven by a high capacity, DC motor. It is
supplied with wire feed kits for 0.045” (1.2 mm)
and 1/16” (1.6 mm) diameter wires and can feed
at speeds from 12 to 600 IPM (30 to 1,525
mm/min).
The hot wire welding process is ideally suited to
welds that have high quality requirements, such
as nuclear or pressure vessel applications.
These welds normally require radiographic or
ultrasonic inspection.
9629HW Speed Control
The control of wire feed speed is effected
through the 9629HW microprocessor controller.
The control sets and maintains the desired wire
feed speed and provides control of wire inching,
speed ramp up at the start of the wire feed and
wire retract distance at the end of the wire feed
sequence.
The process is suitable for a wide range of
materials including carbon and low alloy steels,
stainless steels, nickel alloys and combinations
of them all. Aluminum and copper alloys are
not suited for the process because of their low
resistance to the electrical heating current.
Hot Wire Torch
The torch guides the wire into the weld pool and
is equipped with a contact tip which transfers
the hot wire current through the wire and
provides a protective gas shield to the heated
wire. It is gas-cooled and rated at 200 amps AC
at 100% duty cycle.
In addition to its use for joining, the hot wire
process is an excellent choice for cladding
operations. It produces an overlay with a clean
weld surface, free of spatter, and lower porosity
levels than MIG, FCAW or SAW.

Section IV
Installation and Setup
On receipt of the HWP-50E Hot Wire Welding
system, carefully inspect the various parts of the
system for any damage which may have
occurred during shipping. In the event of
damage, contact the carrier immediately. In
these circumstances, do not use the system until
the damage has been corrected as operation in a
damaged condition could result in further
damage or injury.
Primary Power Connections
The HWP-200E series hot wire power supply
requires 3 phase primary input power. The
model HWP-200E-1-220-A1000 requires a 220
±10% Volt, 3 Phase, 50/60Hz, 3Kva supply.
The model HWP-200E-1-A1000 requires a
380/415/440-480 Volt ±5%, 3 Phase, 50/60Hz,
3Kva supply. The power supply is normally
shipped with the power cord installed and the
voltage preselected for the customer. If,
however, the primary voltage selection needs to
be changed, refer to the following:
Transformer T1 is the larger 3KVA transformer
that supplies the isolated 3 to 15VAC to the hot
wire process. T1 is inherently short circuit
proof.
Transformer T2 is the 250VA transformer that
supplies the 120VAC and 24VAC control
voltages for internal use only, in the power
supply.
HWP-200E-1-220-A1000
For either model of hot wire power supply, the
two transformers, T1 and T2 must be configured
for input voltage changeover:
See also Dwg HWP-200E-1-220-A1000
Connect the 220 volt (208-240VAC) 3 phase
power cable to L1, L2, L3 on the TB1 terminal
block. Connect the ground wire to the input
ground stud bolt on the inside of the rear panel.
There is no neutral wire connection on this unit.
T1 Connections – On transformer T1 (P/N
9749B) jump terminals 1-2 and also 3-4 with
12ga wire on the primary windings. Connect
wire #8 to terminal 4 and wire #9 to terminal 1
of the T1 transformer. This sets the primary for
208-240 VAC. There is never any change in
connections to the T1 secondary.
Maximum Winding Temperature: 65/C

HWP-50E Hot Wire Process
T2 Connections – On transformer T2 (P/N
9751) connect wire #5 to terminal 1 of the T2
transformer primary. Connect wire #4 to one of
the other primary terminals as follows:
Wire #4 to T2, terminal 2 for 208-240VAC
operation. There is never any change in
connections to the T2 secondary.
Maximum Winding Temperature: 65/C
HWP-200E-1-A1000-CE

T2 Connections – On transformer T2 (P/N
9751) connect wire #5 to terminal 1 of the T2
transformer primary. Connect wire #4 to one of
the other primary terminals as follows:
Connect the 3 phase power cable to L1, L2, L3
on the TB1 terminal block. Connect the ground
wire to the input ground stud bolt on the inside
of the rear panel. There is no neutral wire
connection on this unit.
Wire #4 to T2, terminal 3 for 380 VAC
Wire #4 to T2, terminal 4 for 415 VAC
Wire #4 to T2, terminal 5 for 440-480 VAC
There is never any change in connections to the
T2 secondary.
Maximum Winding Temperature: 65/C
System Start Contact
The HWP-50E system is most commonly
started from a remote contact closure provided
by the user. This can be a dry contact or toggle
switch. With this method, use the 9629-S29302-P14 interconnecting cable. (This is the
standard supplied cable.) See the HWP-50E
layout drawing for further details.
T1 Connections – On transformer T1 (P/N
9749B) jump terminals 2 and 3 with 12ga wire
on the primary windings. Connect wire #8 to
terminal 4 and wire #9 to terminal 1 of the T1
transformer. This sets the primary for 380480VAC operation. There is never any change
in connections to the T1 secondary.
The contact closure should be applied at S13,
Pins A and B on the 9302C control or,
alternately, can be applied to RC1 (2 prong
Hubbell) on the HWP-200E power supply
enclosure. Either place may be used with the
same results. The choice is usually determined
by the physical location of the remote start relay
contact.
Maximum Winding Temperature: 65/C
When the contact closure is applied, the wire
feeder will always start. The hot wire power
supply will also start if the toggle switch on the
16
HWP-50E Hot Wire Process
3106A-20-33P mating connector with 97-30571012-1 cable clamp. Connect remote signals as
follows:
9302C control unit is in the “HOT” position.
The contact closure must be maintained and
opened when the hot wire process is to be
stopped.
Apply start contact to Pins E and F.
The 9629HW wire feed controller is slaved to
the system. Pushing the 9629HW start button
will not start the hot wire power supply, it is
used for maintained jog. The Em Stop button on
the 9629HW will stop the wire without retract
but will not stop the HWP-200E power unit.
NOTE: When starting from S2, no start signal
is required at S13 or RC1.
Jump Pins K and L to enable the remote voltage
function. The K-L jumper energizes relay CR4
which switches the voltage control function
from the 93302B control to the S2 connector.
The voltage control pot on the 9302C is inactive
while the jumper is present. Apply 0-10vdc
voltage control signal to Pins A and B. Pin A
should be Hi, referenced to Pin B. 0 volt
reference is approximately 2 vac output, 10 volt
reference will produce approximately 15 vac
output.
System Start From 9629
The system may alternately be started from the
9629HW Start button by using the 9629-S29032-P13 interconnecting cable. See drawings
HWP-50E and 9629-S2-9032-P13 for further
details. When using this method, the Start Delay
for the wire feeder is not active, so the wire
feeder and the hot wire power supply will start
simultaneously with pressing the 9629HW Start
button.
Gas can be controlled remotely by applying a
contact closure to Pins H and J. This function
can be used by itself without controlling voltage
remotely (no jumper between Pins K and L).
When using this input, the hot wire shield gas
can be started before striking the welding arc so
as not to disturb the GTAW or PAW shield gas
as the hot wire process turns on.
Pressing the 9629HW Stop button will stop the
hot wire power supply immediately but wire
will continue if there is time programmed for
the wire feed Stop Delay. Normally, 0 sec Stop
Delay time is used.
Pressing the 9629HW Estop button will stop
both the wire feed and the hot wire power
supply immediately.
Remote Functions Connector S2, 9629HW
If using the remote connector on the HWP-200E
power supply, the remote connector, S2, on the
9629HW wire feed control may also be used for
remote sequencing. Please refer also to the 9629
manual for further details. In this case the
interconnecting cables, 9629-S2-9032-P13 or
P14, will not be required.
Manual Start
To run the system manually without a start
signal, first switch the mode toggle switch on
the 9302C to Setup, then press the Start
pushbutton on the 9629 wire feed control.
Apply a wire feed start contact to S2, Pins A
and B of the 9629HW control. Closing this
contact will start the wire feed sequence,
opening the contact will stop the wire feed
sequence. 9629 Start and Stop Delays will be
active.
To stop, first press the Stop button on the 9629,
then switch the mode switch to Cold (or Hot).
Remote Functions Connector S2, HWP-200E
(Please refer also to HWP-200E Interconnection
Diagram.)
Additionally, the wire feed speed may be
controlled remotely by applying a 0-10vdc
signal to S2, Pins M and N (M is high and N is
low). Note: the “R1" option may have to be
The HWP-50E system can be more completely
controlled remotely by using the S2 remote
connector on the HWP-200E enclosure. Use a
17
HWP-50E Hot Wire Process
purchased to activate this feature on the 9629
control. Part number is 9629HW-R1.
9302C Hot Wire Control
This should be mounted close to the operating
position in such a way that the meters can be
clearly seen during operation.
There is a 0-10vdc feedback signal available at
Pins C and D only when the HWP-200-38®
feedback option is purchased. This is a DC
voltage representative of the AC output voltage.
It can be used for display and/or closed looping
applications.
The unit receives its electrical power from the
HWP-200E power supply through the HWP-200
cable.
HWP-200E Power Supply
9629HW Wire Speed Control
For satisfactory operation of the hot wire power
supply, it is necessary to allow at least 12” (300
mm) of space at the rear of the unit for adequate
ventilation purposes.
This unit is designed to be mounted to a vertical
surface and should be located close to the
9302C control.
The control requires a source of 110 or 220
volts, single phase AC power. See 9629
operation manual for input voltage selection.
The primary electrical connection primary
electrical connection should be made using 14
AWG or larger conductor. Check that the unit
is set up for the correct primary input voltage.
Hot Wire Torch and Positioner Assembly
The wire positioner assembly is designed to be
mounted to the welding torch and is equipped
with a clamping system which accommodates
torches with diameters from 3/4” to 1 ½” (19 to
38 mm). The hot wire torch mounts in the
positioner and should be securely clamped. For
ideal operation, the hot wire enters the weld
pool from the back and the positioner should
therefore be orientated to achieve this.
Secondary connections Secondary connections
to the power supply can be made with #1 AWG
cables, maximum recommended lengths are
100ft (30 m). Where possible, run the torch and
work cables closely together to avoid magnetic
fields.
Connect the gas connection to a supply of argon
gas at a pressure not to exceed 50 psig (3.5 bar).
The torch is connected to the feedhead using the
supplied wire conduit. Select the correct one for
the wire size to be used.
WF-50 Wire Feed Head
This should be firmly mounted to your welding
fixture within 6ft (2 m) of the welding torch and
at such an angle that the wire feed conduit
(when connected) has a smooth curve to aid in
the feeding of the wire. It is preferable for the
unit to be mounted to a vertical surface. Use
5/16” (8 mm) diameter mounting bolts.
The feedhead receives its electrical power from
the 9629HW hot wire speed control through the
cable supplied with the WF-50.
Fit the appropriate drive rolls and wire guides
for the wire size to be used.

Section V
Operation
imparts the electrical current to the wire, is set
back ½” (12 mm) inside the gas diffuser. Check
that the correct contact tip and insulator are
being used for the selected wire size.
Prior to the commencement of welding, it is
necessary to position the hot wire torch to feed
the wire into the correct part of the weld puddle
and to achieve the desired preheating of the
wire.
The torch should be set in the wire guide
positioner in such a way that there is a wire
stick-out of about ½” to 3/4” (12 to 19 mm)
from the end of the nozzle to the work piece.
For optimum results, the wire should enter the
puddle approximately 1/8 to 3/8” (3 to 10 mm)
behind the tungsten electrode or the center of
the plasma stream in the event that plasma
welding is being employed. The actual distance
depends upon the welding current being used.
Higher currents and slower travel speeds allow
the wire to enter the puddle further from the
tungsten.
This electrical stick-out is important for process
control. For a set wire feed speed, a shorter
stick-out will require an increased hot wire
voltage setting while a longer stick-out will
require a decreased hot wire voltage setting to
achieve the desired wire melt condition. Precise
documentation of the stick-out distance, as well
as welding parameters, is important for
producing consistent results from weld to weld.
As the welding current is increased, the arc cone
increases and a larger “dimple” is created in the
weld puddle by the forces in the arc. As the part
travels, the dimple creates a ridge on the back
side of the puddle, just outside the arc cone. It
is important that the wire position be set such
that the wire enters the weld puddle on the top
of the ridge, just outside the arc cone.
The normal gas used to protect the heated wire
from oxidation is Argon. Weld pool size and
welding speeds are normally increased
compared to those without hot wire. Therefore,
it is beneficial to have this additional source of
shielding gas to aid in protecting the trailing
edge of the solidifying weld. Typically, gas
flow rates of 5 - 20 cfh (2.3 to 9.4 l/m) are used.
Note that the gas flow should be established
prior to starting the welding arc to avoid
interference during arc initiation.
In operation, the wire is preheated to a state just
short of melting. In this state, the wire is very
soft and can easily droop. For this reason the
angle at which the wire enters the weld puddle
should be as steep as possible. For best results,
a starting torch angle of 45 to 50 degrees should
be considered. This is mainly for controlling
the desired entry point into the weld pool. If the
wire enters the weld pool at too low an angle,
fluctuations in weld pool height may cause wire
entry point to vary. Increased entry angles also
reduce the effects of preheating the wire
(softening) and wire cast which can combine to
produce changes in the entry point.
For deep groove welding, it is sometimes
necessary to remove the gas nozzle from the hot
wire torch. In these circumstances the flow of
gas to the hot wire torch can be cut off as the
main welding gas flow protects the hot wire as
well as the weld puddle.
The starting sequence of the hot wire weld is
critical as defects can be caused if this is not
done correctly. A correct sequence would be:
As the wire is heated electrically, it is necessary
to have a set wire extension (stick-out) to
produce the resistance heating. Within the
Jetline HWC-200 torch, the contact tip, which
Start the welding current and upslope the weld
to establish a satisfactory weld puddle.
19
HWP-50E Hot Wire Process
At approximately two thirds of the full welding
current, start the wire using the speed ramping
facility in the 9629HW control. The wire speed
should be set to ramp up to the desired speed in
about 3 to 4 seconds. This allows the wire
heating to be gradually established to ensure
that the wire does not enter the weld puddle
while it is still too cold.
During welding, the wire should be close to
melting as it enters the weld puddle. This will
achieve the condition where 90% of the heat
required to melt the filler wire comes from
resistance heating. Thus, the majority of the
welding current is used to produce the weld and
is not wasted in melting of the wire.
If the hot wire current is too high, the wire
separates from the weld puddle and melts back,
forming a ball on the end of the wire. This
destroys the connection between the wire and
the weld puddle and no hot wire current can
flow. The result is a cooling of the wire which
then enters the weld puddle in too cool a
condition. This condition can be recognized by
an audible buzzing and snapping noise and the
wire balls up and then re-enters the weld
puddle.
This is an undesirable condition as the wire is
too cold when it enters the weld puddle and
could cause defects in the weld. For ideal hot
wire welding, the wire should flow freely and
smoothly into the weld puddle.
Hot wire welding allows higher wire deposition
rates than cold wire welding. This can result in
a larger weld puddle and, in order the maintain
a stable puddle, it may be necessary to increase
travel speeds relative to those which would be
used with cold wire techniques.

This is the minimum or offset adjustment. With
minimum input voltage applied, adjust until
output is in agreement, for best linearity.
Please refer to the illustration on the next page
for details of the parts and connection points.
SW501 – Input Type Selector
All switches on SW501 should be off (down, as
in illustration) to select for standard voltage
input. Do not change settings in this application
- damage could occur.
This optional board is used to provide the user
with a 0 to 10 vdc signal that is representative of
the AC output of the HWP-200E power supply.
The input is connected to a generated output
from the PS1 inverter. Output goes to the S2
Remote Connector (Pins C and D).PCM4 Analog Isolator Board

C. Transformer Ratings
Transformer T2 is the 250VA transformer that
supplies the 120VAC and 24VAC control
voltages for internal use only, in the power
supply. T2 is protected by CB1, CB2, CB5, see
Dwg HWP-200E-1-A1000.
Transformer T1 is the larger 3KVA transformer
that supplies the isolated 3 to 15VAC to the hot
wire process. T1 is inherently short circuit
proof.
The T2 primary is configured for different
primary voltages by moving wire #4 to one of
for different terminals on the transformer itself.
See Section IV, Primary Power Connections and
Dwg HWP-200E-1-A1000 for more details. The
secondary connections are never changed.
The secondary winding of T1 is connected to
the HWP-200E output terminals so the hot wire
torch can be connected via weld cables to the 3
to 15VAC output. The output frequency is
continuously variable from 50Hz to 200Hz. The
output current is rated up to 200 amps
continuous and varies with the output voltage
setting and the resistance of the secondary hot
wire torch circuit.
Maximum Winding Temperature: 65/C
The two primary windings must be configured
in series or parallel depending on the primary
voltage (see Section IV, Primary power
Connections and Dwg HWP-200E-1-A1000).
The secondary connections are never changed.
Maximum Winding Temperature: 65/C
