View Full Version : Good price on Miller 320 A/B Set-up??

I'm not a welder yet. Been lurking, learning, looking for something to buy. I have found the following set up locally:

Miller 320 A/B
Water cooled TIG torch, kevlar covering (no cooling pump, runs off tap I guess)
Remote foot pedal
Stick elelctrode holder
Ground Clamp
60cf Gas bottle
Flow meter
Water and gas regulators
Factory Manual

guy wants $400 which I think is pretty resonable, but I'm less than a novice here so I thought I'd ask. For extra he'll deliver to my house.

Intended usage is on everything I can get my hands on :) starting with 1/8" SS and mild steel. I'm looking to fab some trim and safety parts to support my bad habbits. I'd also like to get into AL. Everything that I can conceive of at this time wont be more than 3/16"-1/4". I'd like to do TIG because I believe (from what I've read) it looks better (when done right) and I'm not concerned about producing volume and such.

Questions are:

Is this a good price for a fully functional set up?
Will this do what I intend to do in terms of material variety?

Best regards,


P.S. If this is the wrong forum, my apologies!

I don't find anything about a 320 A/B, but it sounds like a heck of a deal. The gas bottle, while not very big, will run $50.00 or more. The foot pedals aren't cheap. I bought a non-miller one for my rig and it was $150. The torch and regulators would cost a fair amount. If the welder works and if the 320 has anything to do with the amps output, it sounds like a heck of a deal (to me).

If it works and you can use it, it's a good/great deal. Especially with the extra stuff.

You -do- have a way to feed juice to the beast, right? A quick check on Miller's website for old manuals indicates that if the unit is a 300 amp box, it will need the supply circuit to be wired with #2AWG and a 175amp(230V supply) or 200amp(208V supply) breaker.

The 300amp model has a listed weight of 870 pounds, the 200amp model is a lightweight at only 785 pounds.

The 300amp unit has a duty-cycle of 85% at 250 amps, 60% at rated 300 amps, and 35% at 400 amps. The 100% duty-cycle looks like 230 amps.

Will that unit handle 1/8 inch stainless and mild steel? Yeah.

On the Miller website I found a 320 A/BP and A/BSP. I printed the manual for the A/BP and the picture looks exactly like the unit I'm looking at so perhaps the seller forgot the 'P'. The Manual has a publishing date of 1981. When I get in contact with the fellow I'll verify the exact model.

Its a 230V 1 Phase input according to the gent so I think I can wire it up in my garage which will be great as I can back drive my house through the plug from a generator when the Hurricanes knock out the power. If I can't... well I guess I'll have a welder for sale ;)

As far as testing it out, well even if I could strike an arc I wouldn't know if it were good or bad :blush: The advert says that the high feq. functions well and 'everything works'.

For $400 is this unit better than the Harbour Freight 90 Amp TIG unit? Because that's really my only other option. I don't have a spare $1500 for a new inverter style TIG box from Linc. or Mill.

Best regards,
