Have the same problem. Middle of a beautiful weld and would act like the gas was shut off. Pull the trigger and gas would flow properly for a second or two and drop off to a trickle. Found a troubleshooting manual and opened up machine to find out the gas solenoid wasn't getting full voltage and drop off to close to zero after a brief time. PCB3 is bad. Don't want to know how much the board is. Awfully expensive stick welder after a few years of light use.
