I have a 1976 Miller Dialarc 250 and it's tripping the breaker when in the "off" position. As long as it's running or "on" it won't trip the breaker, but as soon as I turn it off, poof, tripped breaker. I've had this welder for almost a year now and this just started happening to...

How you folks doing? My name is Preston. I'm in Baytown Tx(east Houston). I've been welding as a hobbyist for a few years and have several projects completed over the years (mostly automotive). Look forward to being an active member and hope to learn as much as i can from here.
