BTW -- Thermal Arc is a good company and makes good products.
The fact that it's "3 in 1" is just a marketing/sales material ploy. Many of the good machines can do ARC/TIG/MIG.... Not sure why anyone would want to ARC but if you look into it many machines have that capability. Just know that something that does multiple "things" -- there's going to be trade offs... such as set up time -- or things that while it can do "TIG" for example - it may not have a pulse option or slope settings... or any number of other functions that you might want down the road. So when comparing - make sure you know WHAT YOU'RE NOT GETTING... rather than what it "can" do. The THERMAL ARC machine you asked about can NOT do A/C TIG.... so you can not do aluminum. To me that is why I own a TIG machine... so that I can make or repair something that is aluminum. But that's up to you to make that decision. I'm just giving you food for thought.
To me ARC welding capability is like my Gas welding set up.... the only time it ever gets used is to heat something I need to bend. Weld with it? WTF would I want to do that for? LOL
