Apart from my BJ74 my other project is my MGB. Some years ago I used a pinch welder on many of the flanged panels. In my haste to prevent rust, I sprayed Eastwood rust coating paint into the body cavities.
NOW that I have more experience I know those spot welds have poor penetration: the spot welder did it make enough amps.
I have recently drilled flat-bottomed holes through one or two panels leaving the innermost panel intact. I have then tried to plug weld these holes with my MIG. A small fire erupts as the panel's black e primer and the Eastwood stuff ignite. The welds look pretty dodgy and some bashing shows they are weak.
Would flux-cored wire help with this? Could I ever increase the shield gas enough to prevent fire? Straight argon or straight CO2?
Any help or info would be appreciated.
Thanks,
Jamie
