Trailblazer 302 quit

[afpumpman]

Whilst out on a job today, went to stick weld a cap on a well casing. The rod pushed back from the arc like a magnet from another magnet, blew a hole in the steel, and the machine, although seems to run fine, does not weld or make power to the AC outlets. No bad smells from the machine or obvious damage but, it seems terminal.All resets seem to be closed. Any ideas ?

pooched power board, likely due to the engine running too slow at high idle in this case
