Welder Outlet.

[backroad]

I just ordered a new Miller 211 Inverter welder. I'm trying to get my shop setup for it today. My question is this: I currently have roughly 50' of 10/2 wire going from my breaker box across my shop to a 50amp outlet that a window a/c unit runs off of. I believe its tied into a 30 amp breaker but I'd have to look to be sure. Will this outlet work fine for the welder or is the length of run too long? According to the wire calculators I've used and the Miller manual I should be fine, but I want a couple more opinions.

Thanks.

I didn't do an exhaustive search thru manuals but Amazon (known to be light on technical specs sometimes) quotes "input amps 17A @ 230vac".

So I believe you will be fine with a circuit of #10-2 for just the welder.

The question would then become, can the 30A circuit support both the welding operation and the AC operation at the same time. Or, are you intending to uplug the AC and plug in the welder? More info would be needed.

Just going to use one thing at a time. The welder would offset whatever good the pissy little a/c unit does anyway. I'd trash it if it wasn't mounted in the wall.

The 10 wire and a 30 is ideal for that machine. Tailor made circuit. The welder has a 6-50 plug on it.

The manual says 16.6 @ 240v and 24.3 @ 120v...

I keep forgetting the new ones are inverters. Great where a guy needs to use cords.
