And it's capabilities/requirements...

And value with the cylinder and torch/cooler.

It's a Dialarc HF, HF-P great welder bought mine in 1972. Still going strong.

Dial Arc 250. TIG and stick. High frequency. Will do steels and aluminum. Takes 50-100 amps to run properly.

Worth 500-800 depending on condition, location, and accessories.

Solid, dependable, large and heavy. Needs a forklift.

That is an early one I purchased one in 1978 and it did not look like that.
Great machine just what the OP does not need.

just curious is it 3 phase?

just curious is it 3 phase?

AC output = single phase

I earned to tig on one of those. It is a white face so it's 45 ish years old. It is just hitting it's stride. Make certain the MIC-4 control interface works. That one is old enough to use the dinosaur footpedals. How about a level camera shot of the name and logo? Any red? A serial number will give mfg date.

It uses tapped transformer with a variable reactor (?)( I for get the terms.) The HF points move. Use a feeler gauge. It is a diode machine. In that model, they fail every 20 years or so . ( heat kills them. How hard was it used?) Miller's owner and part manual ( available online ) list values so you can buy all four anywhere. I have heard (never seen) of people replacing with SCR for a solid state contactor too.

Cylinder value? Check locally

Radiator value? If it works, run it. That thing may have an ancient radiator core. What did they use for antifreeze and how often was it changed? I can't tell if metal or plastic reservoir. Procon pumps are tough and rebuildable. (Antifreeze is a better lube than water. Was it changed often?)

If dead, fix it. Buy a current model for $500 plus. Switch to air cooled. Use a submersible pump with a 20 gallon blue drum. Does it freeze in Michigan?

I have used them, they work well.

 

[bczygan]

Thanks for all the input guys.

Guy who has it, used it for Alum. TIG on heads.

Asking $750 but may have wiggle room.

That's top dollar for that model. I would prefer any generation, any model of syncrowave.

Head work is high amp but low duty cycle.

I think the floor on this model is forty amps. The footpedals requirements give me the greatest pause. This is old enough to to use the huge wound resister with the carbon wiper. New models are tiny rheostats.

Good machines just not the final word in weld tech. Unless you weld for entertainment, an industrial or near industrial Miller mig would be more useful.

Bill, what is it you're trying to do? You've been posting lots of welders lately. Just wanting to learn? Putter around with one for the hell of it?

Or are you wanting a machine to actually do welding work? Repairs, fabrication and that kind of thing?

To me it's worth nothing due to the extreme electrical requirements this tool has. We're talking about a 90 amp service. You could buy a nice inverter that uses 1/3 the electricity for what running the electric service to that machine will cost you. And they are power hogs in operation. They're bulletproof and work well but they're still a very power hungry tool and it has none of the bells and whistles that modern inverter TIG's have such as variable frequency, Pulse and all that other cool stuff.
