Turn your breaker off then back to on . Your missing a phase

[Bob Welder]

It is a single phase 110/220 machine

Are you running it 220 ? Just flip the breaker off and back on like cruzier said.

[Bob Welder]

I was using the machine on 110 Volts

[cruizer]

OH, yeah its one of those odd units. It's likely stuck on 220, best bring it in, as its having voltage switch issues. The unit senses input voltage, and isn't sensing to drop to 120

I’m having the same problem with my syncrowave 210. Did you ever find a solution to this problem?

How much voltage do you measure from heatsink HS6 in reference to heatsink HS2 when the unit is turned on?

It should measure about 440 VDC when the boost circuit is operating properly in the PC1 board.
