second the strip it and try again approach. those green scouring pads are very good for cleaning switch contacts and put a bit of vasaline on them helps as well.
Does you power selector also turn the welder off ie does it have a "0" position (making it a 7 position) 0= off 1,2,3,4,5,6=power settings ?
I'd give the 27 terminal one a miss (will be sticking out the back of the welder) the 12 terminal 7 position should do you.
Now the wires in your welder.... They are marked up to match your old switch but which is which ie power 1 = ? power 6 = ? Do you know? Also which is the common (power in) one?
