Miller wire welder problem

[WZ JUNK]

I have a problem with my Miller 35 wire welder.  It is an old unit bu it has always worked great.  In the past when I was ready to weld and I touched the wire to the metal, it would make a small spark, then I would trigger the control and start welding.  Now when the wire touches the metal it arcs and starts to weld.  I replaced the solenoid that the trigger controls as I had thought that it was sticking and causing the problem but it did not.  Does anyone have an idea how to fix the welder?  I can use it now but it needs to be repaired.

I think you have a stuck relay. If thats what you replaced, the solenoid the relay controls is stuck. But normally on a Miller, the relay is the problem. Newark electronics has the relay for a fraction of what the dealers get.

You were correct master.  It was the larger relay that was stuck on the one side that makes the wire hot.  I freed it up and cleaned the contact and it is working for now.  I will order a new one.  Thanks again.
