Overkill, but it gets great reviews. Make sure your case has room for it.

I have a small TIG welder that uses somewhat less power... Maybe I could sub in this unit and move up to 5mm welds vs. my present 2.5mm welds...?

IMO, overkill is when you buy more than what you really need/use. corsairs has 80+ % efficiency. 850 is quite enough for your system.

Ok SO im thinking the Corsair but is it a problem that it has only 1 12v rail? What is the benefit of multiple rails?

You didn't read the tutorials !

"Some manufacturers decided to implement one over current protection (OCP) circuit for all +12 V wires, simply trusting the fact that is highly unlikely that at any given time a single +12 V wire would be delivering more than 240 W on a PC power supply, because of what we explained on the previous paragraph. This approach is called single-rail design. In fact some power supplies, especially very low-end ones, don’t have any OCP circuit at all"
