I acquired an 84' Miller SCP-200 welder with a remote plug for the Stabilizer control. The Rheostat for the stabilizer is a 150W 25ohm rheostat. However, Im not finding a remote on any miller sites that suggest which remote will work for my machine. The RHC-3 remote is a 150w 15ohm rheostat. The RHCS-3 remote is a 150w 1250ohm remote which I thought the "S" was designated for "Stabilizer" yet it has a small 5-pin round connector and not the larger 3 prong plug like my unit has for a connection. Does anyone know which remote to use for this machine?
