(Obviously not a trigger button issue.) Hundreds of furious owners have posted online over the last decade, only to see one suggestion: checking the rotating power selector, but that's not the fix for the most common problem source for wire not feeding. THE COLLECTOR CAR GURU Sam figured out the root cause and solution: old nasty grease binding up the many gears in the wire feed motor transmission gear set. Just pull out the motor and transmission gear box (Part number L7801, of which replacements are no longer available), remove the four t20 torx screws on the gear box cover, clean out the chunky old grease apply new grease and reassemble. Remember to check your motor is spinning the correct way, as switching the wires on the motor terminals will reverse motor direction! Apologies for poor lighting and extreme grainy close-ups.
