View Full Version : Welders

I just bought a little lincoln welder to do some sheet metal work with. I get everything hooked up, and when I pull the trigger, the wire feed roller spins backwards, pulling the wire out of the gun cable. What the hell is causing this? I know it's a factory defect, because everything that I had to hook up myself is right. Anyone know if this is an easy fix? I'm assuming there is just a wire crossed some where. Please help!

well, your working with ac so polarity means nothing.
maybe it has the wrong electric motor, or maybe the motor is backwards..
take it back if its new..

Flip the spool of wire, so it pushes the wire. It's backwards

spool of wire is on correct.

I've got a lincoln, but it's at home and I'm vacation till the end of this week. Look at the schematic in the back of the book. I can't remember if the motor runs on AC, or if it takes a tap of the rectifier after it becomes DC. If it does come off the rectifier, then the wires could be swapped. Easiest thing to do is take it back and get another one. If they screwed that up, who knows what else they hooked up wrong.

I fixed it. Just had to reverse the polarity on the drive motor. Swapped the two leads and it works perfect. I used it yesterday with no problems.
