OK, so now I am looking at this arc welder that I inherited and trying to figure out what kind of a circuit it needs. There's no placard on it that says what amperage the circuit should be.

Can you tell by the front labeling? Is this thing any good? (Remember, I'm just a novice newbie learner.)

TIA, Roger

The writing states that it draws 45.5 amps @ 230VAC.
A 50amp double pole breaker and #6 wire to feed it should suffice if the run of wire from the panel
isn't too long.

Don't skimp on the wire feeding the machine.

Other than the low 20% duty cycle it should be fine to learn with.

Looks like private labeled Miller Thunderbolt 225. Had one for years and loved it.
