Botboy, there is something wrong with your Lincoln, you need to get it serviced.

1) there is an internal solenoid that controls gas flow. You pull the trigger, the gas flows, you release the trigger the gas quits flowing. It does not flow all of the time that the bottle is turned on.

2) In like 6 years that I've had it, my Lincoln has never popped any circuit breaker. I weld with it turned up to the highest power setting all of the time. Never has it shut off.
