Replacement Rheostats
These are the most common rheostats used on Lincoln® power supplies. We offer a direct replacement for the OEM rheostat on the SA-200 and other Lincoln® machines. (NOTE: Lincoln never manufactured their own OEM rheostat; they were all purchased from outside suppliers.) Weldmart-Onlinerheostats exceed OEM specifications and carry a TWO-YEAR replacement warranty!
NOTE: We have repair parts for our rheostats! Every item that makes up the rheostat can be purchased separately.
