I picked this welder up off craigslist today. I probably paid too much considering the issue it has.
It turns on fine, but one you hit the trigger it will dim all the lights on a 20amp gfci, and after about 3 seconds trip it or the main. This is no welding mind you and just hitting the trigger without striking an arc.
It will strike an arc for a brief second before it pops the breaker.
I noticed quite a bit of arcing coming from the distribution block, or switch, whatever it is.
Any ideas where to look,? I paid 200 for the welder. I'm hoping to make a nice little welder out of it, but I dont want to drop a arm and a leg into it.
