Has had his share fo thrills with old P&H's.give I'm a PM.

I found them stucturally, almost indestructable, but have no
electrical knowledge to offer.

Hey hooked it up to dryer connection and fired it up is is, all it did was replace the 30amp dryer plug it had on it. Set on low 70 amps and fired it up worked great. Started with small rod at first burned great, put it up to 90amps on low and tried heavy duty rod like they use on pipe lines, wow smooth as butter, this old thing is great. Lays down one nice weld, as good as the welders we use at school. My uncle defitenly gave me a great gift. 7010-P1 heavy duty rod

I would have bet it still worked.
I would consider delicately removing the shell and
clear away the decades of dust (possible bug or rodant nests)

And if there's a fan, blow that out too. If the fan turns freely great,
if not, pull that apart and clean it too.
Relube with just a small amount of light oil.
Then HAVE FUN.

I think your P&H was built in the 1940's because of the curvy art deco style.If all you use is 1/8 inch rod, you should be fine on duty cycle and tripping breaker constantly.P&H was a major welder manufacturer in its time.They made some huge by todays standards tig machines. They also made portables.

I would suspect it is late 40's or a bit later. There are a few P&H models advertised in Popular Science and Popular Mechanics issues of 1948 and 1949, so it seems as though they may have focused some attention on the smaller market about that time.

I don't know exactly when Harnischfeger first made welders. Klaus L. Hansen (orig. from Norway) consulted and designed welders for P&H starting about 1921. Some old P&H ads mention Hansen as though it was a model – latest seen was 1939. Hansen worked for Westinghouse and then Allis before becoming a consultant.

This must be what they considered a portable its on its own dolly of sorts. I bet it weighs 300 pounds.

Well it looks like this old thing will sit around for a few more years. Had a electrician out to run a wire for it, it takes 55amps but theres a problem, my house is old and the wires comming into the house are only 60 amp wires. So he quoted me a price of 1800.00 to run new wires meter box and all. Gonna have to really think on this one, sell, trade, move, lol, **** shame it welds so nice before it throws the breaker.

get another quote, I rescently had a new 200 amp service drop installed for $1200.00 it is a much easier job then you would think, most of the expense is parts, not labor

[Ronnie151]

Any ideas what the value of this thing would be??

I saw a similar old Lincoln Idealarc around here that I probably could have gotten for $75. I don't know what the copper inside is worth.
