Call Larry @ Weldmart-Online (800-460-6474) He's got the best idler out there-grind-ezze built in. You can run an extension cord out 1/2 mile and that sucker will idle up everytime. It comes with instructions-I put mime on in about 2 hours. It would of helped if I knew what the hell I was doing. But I called him (3 times) and he walked me throught it.
He will help you, says he's an old fart-but sounds like is 25-seems to really know his stuff. He offeres an info disc for the SA200-there is a troubleshooting guide for the welder on the disc and its FREE!
