Hi All,

I don't know if this is the right forum for this, but here goes. One of my welders is a Lincoln 175 plus I bought so I could weld thin stuff like body panels. Any way I think the board is out in it, but am not sure. When I pull the trigger the motor clicks but does not advance the wire or give me an arc. I bypassed the trigger, hoping that was the problem but no such luck. I need to dig out the owners manual and see what it says, but thought I would post here also to see if anyone has an idea.

Jay

I dunno, Jay. If the motor clicks that don't necessarily sound like a bad board to me.
Can you check the voltage to the motor when you pull the trigger?

Ya gots ta pull the cover off the thing first. Then a little detective work with a multimeter, may just be a blown fuse. BTW the clicking is likely just the contactor, not the motor.

I have the same machine. Some years ago they did the same thing. Go to LWS (under waranty). They tell me it only a adjustment on the motor.

So maybe it not realy the board. IRC someone here change a motor on a little Miller. Use the search engine.

Good luck

My 175 did the same thing. Change the power level and see if it still does it. The rotary switch is real garbage on these.

The drawing does not show alot of detail of the board. there's also a circuit breaker that may or may not be the problem.

Thanks for the ideas guys. I have been busy pulling new wire in my wireway and conduit so I haven't really checked it out. Sounds like some good ideas, when I get my circuit run so I can plug it in again I will check some of these.

Thanks again, Jay

Try pulling the trigger with the tension roller flipped out of the way and see if the drive roller spins for you. Sometimes the wire can seize in the liner and cause the clicking and lack of feeding you are experiencing.
