• Reduce the amount of tension in the
wire drive tension arm.
• For the best results, use only Lincoln
electrodes.
• Wait 10 minutes for the wire feeder to
cool.
• Verify that nothing is jammed in the
wire drive or gears.
• The ripple of the power source OCV
is too high, greater than 110V.
(Across the Arc Models only)
• Verify that the power source is
reconnected for the proper input
voltage.
