Now I am at my own place so its just the TIG. It is an old gray monster, Lincoln Idealarc TIG 300/300.
Those Idealarcs used to be the hot ticket for small shops. Still a great CC power supply TIG welder.
I just sold my Airco heliwelder V (actually an ESAB 300 Squarewave all bells & whistles) with Bernard cooler. Before that had an Airco mdl 3A(Miller 300S).
My home main panel just doesn't have the ampacity for these older units & with everyone running their A/C the voltage droop wouldn't allow me to.:-\ So I ordered a Miller Dynasty 200 DX inverter TIG/stick. More in line with residential power in the suburbs.
Definitely like the cross frame radiator support you built there. Beefity!
