I am by no means a welder, but i've been doing a lot of rust repair on my 71 and i'm getting better...But I have a question about 'cold welds'.
My last project was on the firewall. I needed to replace a section, and the only metal I had available was some 16 gauge. I welded the piece in with a series of continuous tacks. I had my 120 mig welder on the 'B' heat setting at the start but i was blowing holes in the firewall so i turned it down to 'A'. I welded it all up and then realized my welder's chart actually suggest the 'C' setting for 16 gauge. I'm concerned now it will crack out eventually because i wasn't getting enough penetration. Should i be worried??:huh:
I did turn the wire speed down below 2 when i turned the amps down to A. Hopefully that will help.
