Thanks guys.
Thanks Firefighter,
I was looking at the thermal arc verson like this one at my welding supply store, and found this one online for about half what they were asking.
Looking at the casing and specs, the Thermal, tweco and others are the same unit. I found a good deal that included the tig torch.
I've only tried out the Mig, got it dialed in yesterday and did a few test passes. it welds better than the buzz box I had before.
One thing that I think helps with the price is this model runs on 220 single phase only, not 110/220 like the more expensive versions of the same case.
I don't need to take it mobile for work, so the 220 plug suits me just fine.
Will give more feedback as I use it more.
