You could have done this whole job with a MIG welder, but we ran out of wire in our machine and had to switch to our Diversion 180 TIG welder and ER70-S2 filler wire. Note the use of a heavier MIG glove on the hand holding the TIG torch. The torch gets hot, and so does the work surface. The heavy glove allowed us to hold the torch very close to the tip while bracing our hands on the hot oil pan without getting burned. After fully welding the patch panel, we filled the pan with water to check for leaks. This oil pan is now on a V8-swapped S-10 Blazer street-racer truck.
