7-13. Troubleshooting
Trouble
Remedy
No weld output; completely inoperative
Place line disconnect in On position (see Section 3-13).
Check and replace line fuse(s), if necessary, or reset circuit breaker (see Section 3-13).
Check for proper input power connections (see Section 3-13).
No weld output; meter display on with no
error displayed.
Check to see if the contactor indicator light is lit when contactor line is asserted on.
Erratic or improper weld output with no
errors displayed.
Use proper size and type of weld cable (see Section 3-9).
errors displayed.
Check that proper program for wire size, process, and shielding gas is loaded.
Clean and tighten all weld connections.
No 115 volts AC at the duplex receptacle.
Reset supplementary protector CB1 (see Section 3-7).
Wire does not feed.
Check supplementary protector CB2 and reset if necessary (see Section 3-7).
Check motor control cable connections.
Wire feeds erratically.
Readjust hub tension.
Readjust drive roll pressure.
Clean or replace dirty or worn drive rolls.
Remove weld spatter around the nozzle opening.
Replace contact tip or liner. See gun Owner’s Manual.
Check motor control cable connections.
Wire feeds as soon as power is supplied.
Check gun trigger. See gun Owner’s Manual.
Wire stubbing on low end using a
constant current power source.
Increase output setting of the power source.
constant current power source.
Check voltage sense lead connection, clean and tighten if necessary.
Gas does not flow or does not stop flow-
ing; wire feeds.
Check gas valve and flow meter.
Wire burns back to gun contact tip when
using electrode negative (straight
polarity) process.
Check to be sure that volt sense lead is connected to the work.
