Welder ?

Millers specs on the 140 call for a 20 amp circuit. You may get by on less but be careful where you plug it in.

A buddy of mine has one in his shop about 100 ft. from his house. The entire shop is on a 20A circuit run from the breaker box in the house. When I was showing him how to use the welder we had to dial the power down to around 25% or so to keep from tripping the breaker. The wiring run was just too long and probably too small to begin with...

I use a 10ga 50' extension cord until I can find a way to build a shop to work in and it works very good. It is rated 20 amp but was awfully expensive even at a wholesale price but cheaper than a building for now.

That is why my garage/shop has a 100 amp service. The 220 air compressor and stove(baking paint and powder coating). Yes, make sure your electrical is up to snuff.

I posted from experience. I have a Miller 180 240v. Bought it because I had a 240v line to the garage. After I got it home I realized my circuit was a 20a and the machine calls for a 30amp line. I had one put in. In hind site I should have bought the less expensive 120v machine and changed my existing 240 line to 110. It would have been cheaper and sufficient for what I do.

For an extension cord I went to the local discount RV parts house and bought a 25' 10 gauge rv cord and changed the plugs. About $50 total and I have a nice flexible extension cord.

Where is your breaker box?

My electrical service runs to my house from the outside of the garage. Also, my breaker box is on the opposite wall as of the garage from where it enters. It made it really easy to put two 220v outlets in the garage.

Actually, I put in a third last year when the air compressor went in.

Just a thought. Outlets arn't hard to put in if the breaker box is close.

I also have a Lincoln SP125. Its been a great welder. I have never had it shut down due to overheating because of its operating duty cylce like with my first welder (weldpack 100) The SP125 calls for a 110V 25 Amp connection but I have never popped a 20 amp breaker. (I have done just about as much home welding as one can do with my metal fabrication hobby) I would guess that the miller 180 would have been fine with a 20 amp 220V supply (as long as you don't start the air compressor). Mig welding is nice low smoke welding for in a smaller garage and if you do need to weld 3/16 or larger with multiple passes, the .035 Flux core wire increases the penetration. I also picked up an aluminum conversion kit and a separate tank for argon. Its been years since I welded anything in aluminum. maybe I should try it on my future teardrop?

Here's my 120V welder:


For what I needed, its perfect.
