Welder Wiring
 
Hey guys,

I'm getting ready to add the receptacle to my panel for the 220 line. Can you tell me what size wire I need and the type of plug? I figure a 20 amp fuse.

The welder I will be using is a Miller 211.

Thanks
Dave

sorry but i don't know what a 211 miller is.. a mig??? if so that 20a is a #12 wire, 30a= #10 wire.... go to home depot/lowes and get a 30 plug/outlet, it don't hurt to go higher..

You need to read the specs on your welder. Miller says that the 211 draws 25A at 230V, so you need a 30A circuit. That's a 30A breaker, 10 gauge wire, and a 30A receptical.

Thank you.

Would a 30A or 40A breaker give me better protection. I would rather go one step safer. Thanks

breaker for wire.
 
Per elect code the breaker is to match the wire size used and the outlet and cord should match the machine requirement and the wire=breaker used.... a breaker larger than the one rated for the wire size used could allow the wires to overheat and start a fire. ..in the old days idiots used to put a copper penny under the screw in fuses that have light bulb base and burn houses down.

Stick with the 30A, a 40 would give you less protection as already pointed out ;)

You'd get change back if you gave them a penny for their thoughts...
I saw where a hunter shot himself dead in his truck but the rifle was still in the rack...they thought it was murder until they found the empty cartrige in the fuse block ...the dummy blew the heater fuse and stuck a bullit in there when the short heated up the gunpowder it when off,killing him.... :drunk:

i think that 211 uses a 50a type welder plug
it looks just like a 115v only larger
your welder should give you a recomended amp requirement

Absolutely impossible. A bullet will not move very far from a cartridge unless in the chamber of a gun. Yeah it will move a little bit, but not very far or as fast as you might think.

sounds like a good one for the myth busters.... :mwink: or you could just throw a few in a camp fire ...Ill bet you run....

cal1320 10-16-2011 07:36 PM

Myth Busters did it. Don't think it was plausible.

I did this a couple of months ago except the breaker and plug were already there for my 220v. compressor. I bought a Hobart 187, removed the 6" power cable with a different plug. I got 10' of 10-3 power cable, installed the proper plug and I was in bidness!

Absolutely right, think about it. A loaded cartridge out of the chamber is heated until it discharges. Newton tells you that the heavier of the two pieces (the bullet) will move less than the lighter piece (the case).

I used to laugh at those westerns where they would throw a handful of cartridges in the fire and they would start going off and people would run like it was going to kill someone

Wire size for 180 Lincoln welder
 
Let me tell you about my experience with Lincoln. I was in the process of building the garage so I could easily put in what ever I needed for the welder. I bought the Lincoln 180 wire welder.

On the back panel, it stated the welder only drew 20 amps, the directions that came with the welder said to put in a 40 amp circuit, and there was a 50 amp male plug on the end of the cord. It was all a little confusing. I talked to Lincoln and 3 electricians and here is what I found out.

The welder draws 20 amps while you are welding. When you first strike the ark you can have a surge that draws more. The 40 amp circuit is designed to handle this surge when you first strike up the ark so you will not trip the breaker. The reason it has a 50 amp male plug is that they don't make a 40 amp, and they wanted to have something rated higher than what it would actually draw for safety.

I followed Lincoln's advise and installed a 40 amp circuit which means 8 gauge wire, a 40 amp circuit breaker, and a 50 amp female receptacle in the wall so you can plug in the welder. I hooked everything up and it works great. I would install whatever circuit that miller recommends for the welder. No sense in constantly tripping breakers or burning the garage down to save a few bucks.
