miller 210 use at home.

[larryh]

This is probably a real beginer question but, what problems should I encounter using a miller mig 210 on a house power system. I have installed a 50 amp breaker and have ran 6-3 wire. but, several people have warned me that using a welder on ahousehold power panel could damage other appliences. larryh

Larry,
In general there is no issue with running the welder from the "household
electrics " , assuming everything is sized correctly.
The Miller 210 pulls around 27amp at 230V. Thus your breaker is sized correctly.
Main issue is your overall electric panel capacity. You need to be sure that when your AC, water heater , etc, , kick in when you are welding that the main circuit breaker does not trip. Assuming your overall capaciity is adequate , you should have no problem. An electrician buddy may be able to access your situation.
I recently bought one of the Miller 210's and am very pleased with this unit after moving away from the Cricket XL , 110Vunit.

10-4 David!
You shouldn't have any problems with your "house" current. As long as it's 220-230V and you have the proper breaker as David said, your welder will work great. Keep in mind that you won't be using all the current the machine pulls unless you are in the highest range. If you are in lower voltage settings, your machine will draw less power from your supply.

For future reference, you went WAY overboard on the wire. 6-3 would support a 350amp AC TIG!!!!!! I have a 251 and am running 50 FEET of 8-3, and never had one problem, even when running 1/16" dual shield.

Not only size but length that counts:

Matt, you forgot to mention that wire length can cause more problems than undersize wire. My 350 syncrowave with 145' of 8-3 in the 240-280 amp range will die due to VD,voltage drop.That was a temp test,now it's run on 2-3 SOOW cord. At 385 amp it draws 131 amps w/o power factor, with only 101 amps. Under size wire or long runs will make you hate your welder. Code book states for portable welders you can protect with breaker rated at 200% of welder and wire rated 50% of welder max current. NEC code book. Carl W......=o&o>..........

Thanks for the input Carl!

MILLER machine are more efficient and we recommend 150% on breaker size. All of our wire size and breaker size recommendations are in the owners manuals for each product.
