Update: Total investment is getting up there for the new welder, this stuff adds up fast!
I spent the $315 extra for the TIG torch and Foot Control.
I'll try them out this weekend.
So now I have $599.00 for the multi-process welder + $315.75 for the TIG torch and foot control, a $180 for the Harbor Freight welding cart/cabinet:

Thermal Arc Foot Control 600285 1 181.80
Tweco 17V TIG Torch W4013802 1 133.95
Total 315.75

I already had the 75%Ar/25%Co2 MIG Gas, and 100% Ar TIG bottles, but they would add quite a bit of $$$ to the total (like $500+)
Also, I already have various diameter MIG wire, TIG rods, and TIG electrodes, plus a grinder to sharpen the Tungsten electrodes.
Wow, just adding the TIG capability to the machine doubles the costs (if you don't already have some of the items) by the time you get the gas bottle, torch, foot control, Tungsten electrodes, and filler rods.
