requirements for 220v 180 amp welder
The power cord on your welder may be #12 and not #10 - my Miller 175 has the orginal power cord and it's #12. So if you work from what the power cord for your all the wiring, plug/recept, etc. you may be sizing too small.
I imagine your welder has either a #10 or #12 power cord. I would suggest a minimum a common 30a circuit to power your 180 welder. A 30a breaker, #10 wires to a 30a recept (6-30R) - and then put the 30a plug on the welder power cord itself.
My setup is as above to the from the breaker to the recept30a breaker, #10 wires to a 30a recept (6-30R) - then I have a conversion extension cord from the recept to the welder which has the original/standard welder plug on it.
