... for I bought three more welding machines for resale, despite
having sworn off doing ebay.
So if anyone wants a Miller 330ST AirCrafter single phase TIG welder,
Hobart MegaFlex 450 RVS stick/MIG welder with wirefeed, or a Lincoln
DC-1500 1,500 amp CC/CV welder, let me know
Hmm..I'm not seeing the original post yet. Hey Iggy, how much are you
looking to get for the 330ST? (Probably out of my range, but I've got the
ability to feed it with the right power.)
Hmm...and moving 800#s of machine may be interesting too.
My Brother in Law told me about a school district auction that took place a
couple of weeks ago. Carpet cleaning machines that were last years model
with 10-20 hours on them sold for 10% of new. Apparently they go buy a new
one if there are any issues with machines. Metalworking machine went dirt
cheap too. Wish I could have been there. More tax dollars down the drain.
Decent price, but as I guessed, it was out of my range. (Still have to
pay off stuff from building the power hammer.)
Of course I see there is a 330 A/BP used in my area for only $375. Makes
me wonder how bad of shape it is in.
Our school had a few of that same class machine if that's the machine I
think you are talking about. Big 600 lbs transform machine that does Tig
and Stick. All 3 of their machines are broken at this point and they don't
plan on fixing them as far as I know. They have been replaced with new
The HF contracts would tend to burn out and/or need adjusting but most
common was the diodes would tend to burn out and need replacing (so I was
told). These are machines from the 1980's and the school I think has had
some since that time. They have had to replace the diodes many times over
the years. It's got no electronics (transistors and circuit boards) - just
transforms and relays - and the full schematic is in the manual.
I've heard of those machines going for $50 in working condition at surplus
auctions. They are just so damn big for the power and features that most
people don't want to deal with them any more. Just getting them home is a
problem at that size which is why they don't sell for a lot more.
I wouldn't be surprised if that $375 machine is working. If not, a few
parts like some new diodes will likely get it working. Though I have no
idea how much those diodes might cost.
It was probably the best TIG machine in the shop. It produced an extremely
smooth and easy to control arc. I wouldn't mind owning one if I had the
space (which I don't) and could deal with its size.
That Hobart if it comes with the Mega-con feeder was near $8,000 bucks in
late 80's money (the best Delta-weld 650 ran $5,500). A time when gold was
really king and you paid for it. The parts inside are now supported by
Thermal-Arc (except the lump, if it goes to ground you're toast). When
outfitted with an RVS torch and separate work lead you can move the torch
up and down very quickly and it will hold the arc length (you'll look like
you need medication if someone sees you though).
The Lincoln would be of interest to anyone doing EGW, SAW, FCAW or CC
flood welding, as well as Arc-gouge. It will handle up to 1/2" stick
(1200amps) for forge die flood welding. You might take a small sub station
out if you hook it up wrong though LOL.
Don't know if they are still there but Chicago Ox-weld may be interested
in the Lincoln (they used to do a lot of flood welding).
