I mig 200 won't arc

[Andyco]

Sirs: Purchased an I mig 200 about 1 1/2 years ago and have been very pleased with performance until recently. I was stich welding some sheet metal with flux core (all my welding is outside and breezy) and at about the 30th weld the arc quit. I power cycled, no help. Let rest over night still no arc. Wire feeds ok, green lit on, checked connections inside for tight or arcing. No evidence of arcing inside machine. Fuse ok. Voltage and wire speed windows lit up ok. Have been using 16 volts and 220 wire speed forever. Unit always welds as needed. Lite enough to carry around my truck yard for repairs. Is problem owner fixable? Could use asap.

It's not sounding as if it is. You might want to check your plug though and make sure all your wires are still tight within the plug itself, and check your output at the wall. The green power light is on, or the green light with the exclamation point on?

In your description of troubleshooting you didn't mention that you checked for positive ground... just to take it off the list, how's your ground and ground clamp?

Any btw, welcome, Andyco- I just noticed you're joining us for the first time.

Hey DaveO: Thanks for the welcome. Yes, positive ground. Plugged in and turned the ground plug to the machine a couple of times to make sure was connected ok. Tried arcing to ground clamp and to the exposed copper wires where connects to ground clamp. Zero result. Purchased a used Lincoln sp 120 to finish sheet metal welding. I'm hotrodding a '51 Plymouth. I can live without my Imig for a little while I guess but I do miss it. Its about a good natured welder as I've used. Was a stick welder (SA 200) for years but welding with a wirefeed is so handy and forgiving I don't think I'll go back unless for something only stick would work. Some would say I've gone over to the dark side.

You should see if it will work in stick mode. That my help eliminate some problems.

Tried stick mode. Switched ground to neg. No help..... And to answer Mark, the green "on" lit is on (the upper one). I'm out of idea's. Anybody????
