  42
  • Major physical or electrical damage is evident when the sheet metal cover(s) are removed.

    42
  • The LN-15 does not “power-up” when the on/off switch is turned to the ”ON”position.

    42
  • When the gun trigger is activated the wire drive runs and electrode wire feeds, but there is no welding output.

    42
  • When the gun trigger is activated there is no wire feed.

    43
  • 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.

    43
  • The wire stops or stubs while welding.

    44
  • The wire feed speed range is only 50 to 374 IPM.(1.3 to 9.5m/min.

    44
  • The wire feed speed range is only 50 to 600 IPM.(1.3 to 15.3 m/min)

    44
  • The wire feed motor runs very fast and there is no control.

    45
  • The wire feed speed varies during welding but the meter reading remains constant.
