Will I be able to run this welder? 20 amp in a 15 amp breaker
I would like to buy a 120V welder, 60 Hz, 20 amps, single phase input.
My garage (where it will be used) has a 15 amp breaker. It also runs the lights in the garage and the lights in the kitchen. Even with all the lights turned off, will I be able to use this welder without tripping the breaker? I'm not sure if the 20 amps is the max it will use and the average amps used is under that, or if it needs a constant 20 amps.
Any input?
Thanks

Thats a big negative. I'm sure it might run for you if you tried it, but your breaker, wire, and receptacle are not rated for what you would be using it for. Time to plan out how you're going to install a dedicated 20A receptacle in the garage.

The garage is attached.
Just curious now, but why a 30 amp? If it's for a 20amp, why wouldn't a 20 amp work? Because of the extra amps the lights that the breaker is wired too also?
Thanks!!

Based on the 20% duty cycle, a 20A 120V circuit with a 20A single receptacle on a 20A gfci breaker should be fine.

I have a Clark 120 volt MIG which will run on a 15 amp circuit for a little while. It will trip the circuit if I push it too long. It has not problems on a 20 amp circuit.
The plug on the unit you linked to has a 15 amp cord so I suspect it will run about the same as mine.
From your manual:
Flip the Power Switch to the OFF position, then plug
the Welder into a dedicated, 120 V~, 20 A circuit
with delayed action type circuit breaker or fuses.

Chances are that this is a no go. The next questions is, what gauge wire was used? Depending on the length of the total run and the gauge of wire used, you may just be able to upgrade the breakers and the outlet.
