Thermal arc huh, funny I checked out the thermal arc 186 ( couple videos on you tube)and I liked the features and room to learn ( more settings I can learn on) it would be almost the same cost as the diversion 180.
I do have a stick machine already( lincoln 225 ac) but that doesn't matter. Keep it coming, I'm on the fence. I like the thermal arc 186 argument even if it is a overseas unit:/
