I saw the post the other day about a Lincoln welder
with no power to the leads....WELL mine is doing it
now! I shined up the brushes and armeratures,
checked all the connections, and cleaned a few
things up. STILL no power! Any ideas? The thing RUNS
great! Now -- if it would just WELD....
I last used it about 2 weeks ago, and it worked
great.
 
If you have pushed on the brushes with a screwdriver while it is running and it doesn't work I would try some jumper cables and a 12 volt battery on the welding cable posts. Seems like this worked on one for me a long time ago. Vic
 
D It was I that had the problem with a sae 400 linclon. Had several replies on here and did what you say you have done. No luck. Called Linclon and they told me to do two things. Don,t know which worked but mine is now working again. It has a switch to co from positive to negative polarity, they suggested I switch that hard several times. They also told me to take a knife raise the brushes and put crocus cloth rough side up and work on the brushes. One of the two things worked because after doing both it welds perfect.
 
Yeah - I ran that polarity switch back and forth several times, and it fired up! Odd how it hadn't done that to me before, and it picked the same time that yours did it! By the time I was gonna weld, Lincoln was not answering their phones, so I wracked my brains until I remembered something from way back - I tried it, and it worked.

I love this machine, but it is realy overkill for what I need. I'd like to sell it and get a smaller unit.
