Older Miller Dial Arc 250 AC-DC welder

(1/2) > >>

What do you guys think for $300? 

Just have pictures of it right now.  My buddy up the road from me has picked it up and will deliver to me in the next week or two.  The welder was pulled from a welding shop near my buddy's place.  It was under power and working fine.  The new owner of the shop wanted it out of there, MIG welders was his method of getting things done.  At least that is what I was told.

I'm not sure I have enough juice coming in my place to run it.  Everything I've read about this model welder, most people run it on a 50 amp breaker.  I'll find out if they are right.

chips and more:
It looks like the transformers have copper windings? A long time ago I had a stick welder with aluminum windings. What a POS. Very poor duty cycle. Could not even get through one rod without duty cycle problems.

Yes, this one has copper windings.

I've had one for about 30 years Ken, great welder, but certainly not portable. There's probably $300 scrap copper in it.
Has enough jam that rods never stick when starting an arc.
They had an optional remote for the current setting, I bought the rheostat from Miller and made one. Mounted in a metal box with a 3 wire heavy extension cord connecting it.
Im using a 50 amp breaker, might run on a smaller one at lower settings?
Like the shop your getting it from, I mostly use MIG


Depends on your situation whether you already have a welder and this is just an “opportunity “ if so I’d pass.    Its a legacy unit. Miller may or may not support parts.  They are durable and usually 100% duty cycle at full amperage but transformer welders take lots of juice and are heavy to move around.    Might be good for production work at a static work station.
The cost of materials to run the electrical req might be $300 and then you’re stuck thereabouts.
Or if its got enough copper and you wanna play Sanford and Son for a few bucks I suppose.
