older norweld machine problem

[Clifford]

i have a older machine that is blue and white, it says nor weld on the side... I am looking for a new rheostat for the machine. the old one says

Colvern 11/135/M50
10kk
8544


It has 3 purple wires coming from it.. Anyone have any ideas where I could find a rheostat to replace the current one. thanks in advance.. Cliff

Hi
You can try at elctronics spare parts shops/depots or if you have near by an elctronics junk yard - it will be much cheaper. you have to notice two things: the resistance value and not less important, the wattage of it. in both casae you will be better of if you take along your old rheostat.
Good luck.
