I-MIG 200 intermittent shutoff issue (green warning light)

I'll keep an eye on the spatter buildup, then, and see if that's a factor on when it trips. I can't say I was paying close enough attention to say one way or the other right now.

Spatter can bridge inside the nozzle. I do know that, and have experienced it myself, particularly overhead. I use a wider one that I bought from HF that allows more space inside for easier cleaning. If the nozzle bridges to the diffuser inside, or gets pretty close, it definitely will do that, especially if the nozzle touches the metal when you start. Make sure your wire isn't on the weld when you start, by clipping the end when before you restart, if it is a little on the long side, with a pair of mig pliers...

Maybe your extension cord is too long or the wire is too thin, causing the overheating.

50' of 8ga SEOOW should be fine in that regard, thanks for the suggestion though.

I think mark may have nailed it with the spatter bridging between the cup and the contact tip. all it takes is one good sized BB to fall off and wedge down there, then bump the cup into the workpiece or what have you.

[Joe from NY]

yeah, no doubt.

Mark is talking about the one on the right in this link.

We use both, but my son is always tapping the nozzle to get spatter out. Have not have the IMIG-200 short yet. But we spend some time cleaning out the nozzle.

Mike,
That's the one.

I don't know squat about mig, but by my understanding, the cup is just channeling the shield gas, correct? Seems like a non-conductive cup or cup lip would be a good solution. I was thinking ceramic, but that would be brittle and subject to breakage if you weren't careful.

Mig pliers are shaped like a reamer, with sharp edges, for that purpose.. they work good.

If the nozzle or wire is touching your work when you pull the trigger, the warning light will come on and the machine will not operate until you power cycle it (turn it off then back on). The nozzle on my new profax torch is insulated as is the miller torch that came with my hobart welder.
