    Syncrowave 250 no remote TIG output

    I bought this 250 syncrowave about 10 years ago at a Navy auction, at the time it was sold in working order, I just got around to cleaning it up and hooking power to it yesterday. She stick welds fine and Tig welds from the panel, but the HF doesn't work. The problem im having is on TIG remote. When the pedal is depressed the CR2 relay just buzzes, not locking into contact, I checked the voltage going to the relay coil and it is only getting 13 volts, the relay says its 24 volt. I've checked the pedal out, everything there reads correctly and good clean contacts. The serial number is KA815336. Any help is greatly appreciated.

    Embarrassed to admit I figured it out, the jumper taps were set for 460v and I had it hooked to 230.

    That's a great fix and a lot better than the other way around!

    I've had my 250 for 5 years or so. I bought it from my welder repair guy after my Dialarc 250 was deemed not worth fixing the tig function on. I've been playing around tigging though I'm not very good at it I do like trying. But my surprise was what a good stick welder that thing is. I used it to stick for the first time a week or so ago and it is a joy to weld with.
