Wear dry, hole-free insulating gloves and appropriate body protection. WARNING 3.Disconnect input power before installing or servicing this equipment. Lockout/tagout input power according to OSHA 29 CFR 1910.147 (see Safety Standards). CALIFORNIA PROPOSITION 65 WARNING This product contains chemicals, including lead, known to the state of California to cause cancer, and birth defects or other reproductive harm. Wash hands after use. §248224 A. 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. 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. 6.When making input connections, attach proper grounding conductor first - doublecheck connections. 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. Frequently inspect input power cord for 7. damage or bare wiring. Replace cord immediately if damaged - bare wiring can kill. 8. 9.If earth grounding of the workpiece is required, ground it directly with a separate cable - do not use work clamp or work cable. Have all installation, operation, maintenance and repair work performed only by qualified people. B. 10.Do not touch electrode if you are in contact with the work, ground, or another electrode from a different machine. 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. Turn off all equipment when not in use. 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. 13.Keep all panels and covers securely in place. 14.Clamp work cable with good metal-tometal contact to workpiece or worktable as near the weld as practical. Do not touch live electrical parts. -1- CWF-50 Cold Wire Feeder C. 4.Read the Material Safety Data Sheets (MSDS) and the manufacturer’s instruction for metals, consumables, coatings, cleaners, and degreasers. Arc Rays Arc rays can burn eyes and skin; noise can damage hearing; flying slag or sparks can injure eyes. 5.Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watch person nearby. 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. 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. 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. 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. 3.Wear approved safety glasses with side shields. 4.Use protective screens or barriers protect others from flash and glare; warn others not to watch the arc. E.Cylinders 5.Wear protective clothing made from durable, flame-resistant material (wool and leather) and foot protection where necessary. D. Cylinders can explode if damaged. 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. Fumes and Gases Fumes and gases can be hazardous to your health. 1.Protect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. 2.Install cylinders in an upright position by securing to a stationary support or cylinder rack to prevent falling or tipping. 1.Keep your head out of the fumes. Do not breathe the fumes. 2.If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes and gases. 3.Keep cylinders away from any welding or other electrical circuits. 4.Never weld on a pressurized cylinder - explosion will result. 3.If ventilation is poor, use an approved air-supplied respirator. -2- CWF-50 Cold Wire Feeder 5.Use only correct shielding gas cylinders, regulators, hoses and fittings designed for the specific application; maintain them and associated parts in good condition. 6.Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared according to AWSF4.1 (see safety Standards). 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. 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. 8.Read and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1 listed in Safety Standards. 8.Wear oil-free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap. G. F. Moving parts, such as fans, rotors, and belts can cut fingers and hands and catch loose clothing. Welding Welding can cause fire or explosion. Moving Parts 1.Keep all doors, panels, covers, and guards closed and securely in place. 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. 2.Have only qualified people remove guards or covers for maintenance and troubleshooting as necessary. H. EMF Information Considerations About Welding and the Effects of Low Frequency Electric and Magnetic Fields 1. Protect yourself and others from flying sparks and hot metal. The following is a quotation from the General Conclusions Section of the U.S. Congress, Office of Technology Assessment, Biological Effects of Power Frequency Electric & Magnetic Fields - Background Paper, OTA-BP-E-53 (Washington, DC: U.S. Government Printing Office, May 1989): 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.Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. 5.Watch for fire, and keep a fire extinguisher nearby. -3- CWF-50 Cold Wire Feeder I. “.... there is now a very large volume of scientific findings based on experiments at the cellular level and from studies with animals and people which clearly establish that low frequency magnetic fields can interact with, and produce changes in, biological systems. While most of this work is of very high quality, the results are complex. Current scientific understanding does not yet allow us to interpret the evidence in a single coherent framework. Even more frustrating, it does not yet allow us to draw definite conclusions abut questions of possible risk or to offer clear science-based advice on strategies to minimize or avoid potential risks.” Principal Safety Standards Reference as applicable Safety in Welding and Cutting, ANSI Standard Z49.1, from American Welding Society, 550 N.W.

The cold wire feeder is designed to supply filler metal to the weld puddle in a mechanized tungsten arc welding application. The system will accurately feed 0.020”, 0.030”, 0.035”, 0.045”, 0.062” and 0.093” (0.5 to 2.4 mm) hard and soft wires for mechanized TIG or plasma welding. Note: The wire guide positioner can be used either as a left hand or right hand assembly. To change configuration as supplied by factory, reverse thumb knob, set screw, and spring. (See WGP-1 drawing. item numbers 13, 18, and 24.) The wire feeder can be mounted as an assembly or the components can be removed from the mounting plate and installed in a number of positions with respect to each other. 4.Spool adapter: holds 12” (305 mm) diameter wire spools. The system consists of a 9629 control, D.C. motor-driven four feed roll assembly, spool adapter, and a wire guide positioner. The positioner incorporates X-Y-Z movements of the wire tip. The positioner includes a universal torch mounting bracket. 5.Wire Feed Accessory Kit: conduit, feed rolls, inlet guides, outlet guides, and tips for 0.020”, 0.030”, 0.035”, 0.045”, 0.062” and 0.093” (0.5 to 2.4 mm) hard and soft wire. Order kits separately for desired wire size. The basic components of the wire feeder are: (See Figure 1) 1.Wire drive unit: consists of motor, drive housing, and wire spool assembly to feed wire. (Part number CWF-50-DA.) 2.9629 Control: includes a keypad, display, encoder control knob, start, stop, and emergency stop switches. The SCR motor controller is built into the control box and provides a wire feed speed of 4 to 200 IPM (10 to 508 CPM) with a speed holding accuracy of +1% of base speed. For operating details and function of controls, see 9629 Quick Start Guide. -5- CWF-50 Cold Wire Feeder 6' CABLE (1.8M) UP DOWN ADJUST etline ® e n g in e e r in g Series 9600 CONTROL E-STOP REV POWER START FOR STOP CWF-50-DA COLD WIRE FEEDER 9629 WIRE FEED CONTROL etline etline ® ® e ngi ne e ring e ngi ne e ring MADE IN U.S.A.

(1830 mm) of cable between the control and the wire drive assembly. The control is typically mounted near the feeder due to the length of the control cable. a.The inlet guide should be inserted until the “set screw” properly aligns with the notched section on the guide. The closer the tapered tip is to the feed rolls the better. 1.To mount the wire drive assembly, transfer mounting holes from the wire feeder’s aluminum mounting plate to the mounting surface. (See Figure 2 for mounting hole dimensions.) b.The intermediate guide needs to be inserted prior to the mounting of the feed rollers. The intermediate guide also has a “notched” section which should align with the screw holding it in position. 2.The 9629 control must be mounted in a suitable manner providing adequate ventilation. The control should not be mounted in a high temperature environment. c.The feed rolls need to be mounted securely. If not tightened, they will loosen and will eventually fall off. d.The conduit assembly is then fitted into the outlet guide assembly. This step may need to be repeated in order to fit it correctly. First, the end and inside of the conduit must be deburred. The wire must slide freely into the conduit. 3.Slip the wire guide positioner onto the torch barrel and tighten the wing nuts. You may choose from one of three sets of mounting holes depending upon the brand of the torch to be used. The wire guide tip angle should be set roughly by positioning the guide and tightening the screw. The tip should be approximately on the same level as the tungsten. Next the conduit should be chamfered. The conduit needs to be as close as possible to the feed rolls in order to avoid “bird-nesting”, especially on soft wires. Putting a chamfer on the conduit allows you to get the conduit very close to the feed rolls. 4.Select the wire feed accessory kit for the size wire your application requires. The kit will include inlet and outlet guides, conduit, wire guide tip, and feed rolls. Be sure all components match the wire size to be used. (Refer to Figure 3) At this point, slide the conduit through the outlet guide. You should extend the conduit beyond the tapered end of the outlet guide approximately 1/4” (6 mm). Tighten the set screw securely, holding the conduit properly in position. Proper installation of the wire feed kit is very critical to the successful operation of the cold wire feed unit. Proper installation helps avoid “bird-nesting” at the feed rolls and smooth wire feed delivery into the weld puddle. -7- CWF-50 Cold Wire Feeder The wire guide tip is held in position by a set screw. The tip can slide into the clamping mechanism on the WGP-1 Wire Guide Positioner. e.Insert the outlet guide/conduit assembly into the drive roll assembly. Position it so the chamfered conduit is very close to the drive rolls. (Make sure the end of the outlet guide is clear of the drive rolls.) Tighten the outlet guide securely by turning the hand knob. 5. Electrical Connections: As standard, the feeder is shipped with an electrical connector and 6 ft. (1380 mm) cord suitable for 115 volts 50/60 Hz power supply. Operation for 220 volts is configurable. f.Run the conduit to the torch as required. Remember sharp twists and turns affect the flow of the wire. Test the path of the conduit with the torch in its fully retracted and extended positions. If you need to start the wire feeder from a remote signal, you must supply a normally open, maintained contact closure to Connector S2, Pins A and B. If the conduit is too long, cut the end, making sure it is completely deburred. g.Strip 4” (100 mm) of the outer cover on the conduit. Slide the bare conduit into the wire guide tip. Tighten the set screw holding the conduit securely into position. Note: On a rare occasion, you may have to pull this end of the conduit from the tip when initially feeding wire. Let the wire extend about 6” to 8” (150 to 200 mm) beyond the conduit and then feed the wire into the tip until the conduit is back into normal position. -8- CWF-50 Cold Wire Feeder Figure 2 Mounting Plate Dimensions -9- CWF-50 Cold Wire Feeder - 10 - CWF-50 Cold Wire Feeder Section IV Operating Instructions A. tungsten. This action could also cause adverse effects with the arc length control. Preparation for Welding Mount the spool of welding wire on the spool adapter so the wire will be pulled from the low side of the coil. Adjust the friction brake on the wire spool by adjusting the screw in the center of the spool. If adjusted properly, the spool will feed smoothly and will not coast or continue to spin when feeding stops. When the wire is inched forward, this is a good time to verify the wire’s position. Adjust if necessary. 3.Retract wire to desired starting position using the Reverse key. 4.Check wire and wire spool briefly. Verify there is enough wire for the next weld and that the wire is not wrapped around the spool holder. Debur the end of the wire, then insert it into the inlet guide through the feed rolls and the outlet guide. (Refer to Figure 3). Press the power switch to the “On” position and feed the wire into the conduit by pressing “Forward” key. Continue to feed the wire through the conduit and the wire guide tip until a desired amount extends beyond the tip. 5.Check wire feed speed setting, the start delay setting, and the stop retract setting. These settings are critical to achieve the desired weld. 6.At this point, the unit is ready to feed wire. If the starting and stopping of the wire is controlled remotely, the control will go through the start delay. Once this delay has timed out, the unit will proceed to feed wire at the rate set on the dial. See the Quick Start Guide for various jog modes. B.Operation 9629 Control: The operation of a CWF-50 is not difficult. The following sequence is suggested: When the remote start signal quits, the unit will go through the stop delay, then stop. The unit then proceeds to enter the wire retract time, pulling the wire out of the weld zone. This action prevents the wire from sticking in the weld puddle at the end of the weld. 1.Turn on power to unit. 2.Using the Forward key, inch the wire forward a little. Trim the wire if there is a ball on the end of the wire. This step is especially necessary if feeding wire and using an arc length control. A ball on the end of the wire could touch the tungsten when feeding initially. If the wire contacts the tungsten, you will get a “ball” on the end of the tungsten. The operator should stop the weld and resharpen the Note: If the retract time is set too long, the wire could retract up into the wire tip. If this happens, the wire could, on occasion, get stuck on the tip on the next weld. - 11 - CWF-50 Cold Wire Feeder 7.If the unit is used manually, the operator will press the Start button when ready to feed wire. The start delay will NOT be activated when using this method. Wire will feed immediately once in the Run position. When wire is no longer required the operator presses the Stop button. The unit will stop feeding wire immediately and go into the wire retract procedure. C. Wire Guide Positioner Several adjustments are provided on the wire guide positioner in order to permit the exact position of the wire as it enters the puddle. 1.Lateral adjustment of 1/4” (1/8” adjustment of tip on each side of weld seam). (6.4 mm total adjustment, 3.2 mm on each side.) 2.Vertical adjustment of 1/4” (6.4 mm) tip to work. 3.Coarse adjustment of guide tip angle, by loosening screw and setting in approximate position. The wire position should be checked at the beginning of the weld. Jog the wire forward through the control and make required adjustments on the positioner. Wire typically enters the weld puddle at the leading edge of the puddle. The wire should contact the work piece about .04” (1 mm) in front of the weld puddle and slide under the center of the welding arc. Check tension of drive roll spring. Too much pressure will deform the wire and too little pressure will cause wire slippage. - 12 - CWF-50 Cold Wire Feeder Figure 3 Wire Feed Accessory Kit Components - 13 - CWF-50 Cold Wire Feeder - 14 - CWF-50 Cold Wire Feeder Section V Wire Feed Accessory Kits Wire Size 0.020” (0.5 mm) 0.030” (0.8 mm) 0.035” (0.9/1 mm) 0.045” (1.2 mm) 0.062” (1.6 mm) 0.093” (2.4 mm) *Complete Conduit - 6 Outlet Inlet Guide Wire Guide Feed Rolls **Curved Accessory ft (2 m) Guide Tip & Inlet Wire Guide Kit Guide Tip 20B6020K 42-23 OG-020 056192 WGT-020 053693 N/A PT-40-NAT 20B6030K 44N3545 OG-035-45 056192 WFT-030 046780 CWGT-030 20B6035K 44N3545 OG-035-45 056192 WGT-035 046781 CWGT-035 20B6045K 44N3545 OG-035-45 056193 WGT-045 046782 CWGT-045 20B6062K 45N116 OG-062 056195 WGT-062 046784 N/A 20B6093K 18630F OG-17 056196 WGT-093 046789 N/A *Includes inlet and outlet guides, feed rolls, wire guide tip, and 6 ft (2 m) conduit. **Requires WGP-3 wire guide positioner for curved tips.

Occasionally check the wear of liners, tips, and guides. Always replace fuse with one of equal value — 3 amp fast blow. Periodically check, and replace if necessary, the carbon brushes on the motor. Failure to replace worn brushes could cause severe damage to motor control. WARNING Maintenance and electrical work must be performed by experienced and trained personnel. CAUTION Whenever repairs are required, always turn all power controls off and disconnect all electrical cables from power supply. - 17 - CWF-50 Cold Wire Feeder - 18 - CWF-50 Cold Wire Feeder Section VII Optional Accessories Jetline offers the WGP-2ES motorized positioner so the operator can adjust the position of the wire from a remote location. The positioner includes the motorized wire positioner, the motor control, and a joystick pendant which the operator uses to move the wire guide tip to the desired position. Speed of motion is adjustable to provide accurate positioning as desired by the operator. When you purchased your cold wire feeder, you may not have been aware of optional enhancements for your unit. Jetline is pleased to offer these enhancements which can be added to your system in the field. If you are interested in these features, please do not hesitate to contact Jetline directly or the nearest distributor for more information. A. 607B Spool Cover C.WGP-3 Compact Wire Guide Positioner The 607B is a clear plastic cover designed and manufactured for Jetline’s wire feeders. The cover mounts around the spool holder and encases the standard “30 lb/12 inch” wire spool which fits onto the spool mounting adaptor. The main purpose of the cover is to protect the wire from dust and weld particle build-up. The clear plastic allows the operator to see the spool effectively. Installing the spool cover is a simple, perhaps 5 minute, job. In some applications, the space envelope required by the standard WGP-1 is too large. Jetline manufactures a wire guide positioner which requires less space, yet still gives the operator the ability to adjust the wire position. The WGP-3 is designed to attach directly to the torch, but includes a curved wire guide tip. Wire is fed vertically until the moment where it is angled into the weld puddle. B.WGP-2ES Motorized Wire Guide Positioner D.CHWS-100 Wire Straightener In some applications, minor deviations in wire position are a result of the cast in the wire. The wire straightener can help limit the twist by using a 3 roll action. Tension on the center roll is adjustable. The unit mounts on the inlet side of the drive roll assembly. The straightener is designed to work on 0.035” and 0.045” (0.9/1.0 and 1.2 mm) wire. The standard wire feed unit is provided with a manually adjusted WGP-1 wire guide positioner. In some applications, the operator cannot easily get to the positioner to make the desired alterations to the wire’s location as it enters the weld puddle. Due to the cast and helix in some wires, the need to adjust the wire’s position can be required. - 19 - CWF-50 Cold Wire Feeder - 20 - CWF-50 Cold Wire Feeder Section VIII Parts Lists The following parts lists are included in this manual.
