robodog Posted December 14, 2010 Share Posted December 14, 2010 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 Quote Link to comment Share on other sites More sharing options...
Tormented Soul Posted December 14, 2010 Share Posted December 14, 2010 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. Zach Quote Link to comment Share on other sites More sharing options...

Nakedanvil - Grant Sarver Posted December 14, 2010 Share Posted December 14, 2010 Looks like private labeled Miller Thunderbolt 225. Had one for years and loved it. Quote Link to comment Share on other sites More sharing options...
