ARC RAYS can burn eyes and skin. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld. D Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). D Wear approved safety glasses with side shields under your helmet.

Front Panel Controls Of Feeder (Air-Cooled Model Shown) 1 Voltage/Wire Speed Meter (Optional) 2 Voltage/Wire Speed Switch (Optional) 3 Run-In Speed Control 4 Jog Switch 4 5 Burnback Time Control (Optional) 5 6 Spot/Continuous Switch (Optional) 7 Remote Voltage Control (Optional) 8 Power Switch 9 Time Range Switch (Optional) 1 2 3 11 6 7 10 10 Spot Time Control (Optional) 9 11 Flowmeter (Optional) 8 151 780–A 4-2.
PAGE 29
4-4. Run-In Speed Control 1 Run-In Speed Control Use control to set wire feed speed before arc initiation. 1 After arc initiation, wire feed speed is controlled by the Wire Speed Control on the welding gun (see Section 4-12). The scale around the control is percent of full range, not wire speed. As a general rule, set run-in speed lower than welding wire feed speed. Set control at 0 (zero) for scratch start. Ref. 176 700-A 4-5.
PAGE 30
4-7. Spot Controls (Optional) 1 Spot/Continuous Switch Use switch to select either an untimed continuous weld cycle or a timed spot weld cycle. Both weld cycles consist of the following steps: run-in, weld (untimed or spot time), and burnback. 2 3 4 Time Range Switch Use switch to select spot weld time range. 3 Spot Time Control Use control to set spot weld time. Welding wire feeds at speed selected on the gun Wire Speed Control. Spot time starts at arc initiation.
PAGE 31
4-10. Flowmeter (Optional) CAUTION Wire feeding system is designed for maximum of 50 psi (345 kPa) gas pressure. • Be sure that regulator/flowmeter has preset conditions of no more than 50 psi (345 kPa) gas pressure. 1 60 50 50 40 40 30 30 20 20 10 10 Flowmeter 2 Valve Use flowmeter to control shielding gas flow at the feeder. The scale on the flowmeter is in cubic feet per hour (CFH). Read gas flow at the widest part of the float in the meter.
PAGE 32
4-12. Gun Controls 1 Trigger Press trigger to energize welding power source contactor (if applicable), start shielding gas flow, and begin wire feed. For shielding gas preflow and postflow, partially press trigger before and partially release after welding. 2 Wire Speed Control Use control to adjust wire feed speed. The numbers around the control are for reference only. 1 2 Ref. 802 536 4-13. Shielding Gas 1 Shielding Gas Cylinder 2 Valve 3 Gun Trigger Open valve on cylinder just before welding.

Pull out contact tip. 1 3 Contact Tip 4 Nozzle Pull wire out nozzle and liner should slide out. If necessary, tilt nozzle down to remove liner. 3 Close pressure roll assembly. Reinstall top cover.
PAGE 38
5-8. Removing Contact Tip Adapter In Water-Cooled Models WARNING WATER IN GUN PARTS can cause ELECTRIC SHOCK and can lower weld quality. • • • Turn Off welding power source and water supply before working on gun. Stop engine on welding generators. Always point gun downward when removing water-cooled barrel to keep water out of gun parts. Wipe gun dry before putting it back together. Turn Off weld control and welding power source. 3 1 Nozzle 2 Nozzle Adapter Remove as shown.
PAGE 39
5-10. Adjusting Hub Tension Turn On welding power source and wire feeder to make this adjustment. 1 Wire Speed Control Adjust control to wire speed for welding. 2 2 1 3 Jog Switch Push up, and then release Jog switch. Hub tension is okay if wire unwinds freely, but wire does not backlash when Jog switch is released. 3 Cap Screw Turn cap screw to adjust hub tension. Do not overtighten. Turn Off welding power source and wire feeder. Close and latch door. Tools Needed: 7/16 in 151 778 / Ref.
