- When the gun trigger is activated the wire drive runs and electrode wire feeds, but there is no welding output.
- When the gun trigger is activated there is no wire feed.
- The wire feeds for a short period of time but then stops feeding. When the gun trigger is released then re-activated the wire resumes feeding but soon stops again.
- The wire stops or stubs while welding.
- The wire feed speed range is only 50 to 374 IPM.(1.3 to 9.5m/min.
- The wire feed speed range is only 50 to 600 IPM.(1.3 to 15.3 m/min)
- The wire feed motor runs very fast and there is no control.
- The wire feed speed varies during welding but the meter reading remains constant.
- No shielding gas.
- The shielding gas turns on sporadically, or remains on all the time.
