What size wire 125’ to garage,will have 50 amp welding machine and led lights only use at the same time.Plan to use underground cable.

  • I take it this is a detached garage, correct? Also, are you buying this 50A welder, or do you already have it sitting in front of you? – ThreePhaseEel May 18 at 2:02

    Is it a 240V-only welder, or does it need a neutral? Will you NEVER power any 120V devices out in the garage (or do you already have a 120V circuit coming out there?) – Harper May 18 at 14:39
  • As Bob the Builder points out, can you answer: Detached or attached garage? What is the total distance of the wiring run? What is the amp capacity of your current service/loadcenter? What else do you foresee running in the garage at the same time as the welder? Honestly without detailed info you won't get an answer (at least not here, other forums will cheerfully turn insufficient data into a terrible answer, as can Home Depot employees). – Harper May 20 at 15:49
