its the white box in the middle at the top
that looks like a transistor to me as its got three legs and a heat sink!
its just a "sub miniature" relay its quite normal for that size to be black or white
i think i have miss identified the component as it is coming back as a big resistor. IS there anything on the back of the circuit board?
how old is the welder? has it always had a live torch? is it second hand?
