Bought a Stack of 3-phase Miler Welding Machines, have no idea what they are worth...

Excuse me, this is my first post and I know how annoying that can be, I moderate a few other forums online. However, I know just enough about welding to be dangerous and found this forum so I have high hopes!

I went to an company auction we had recently and bought a bunch of metal (beam, tubing, etc). There was a ton of stuff there for sale including forklifts, ironworkers, and even welding machines. There was one Miller that was an old 240V machine I wanted. I am putting up a shop this fall and wanted a machine in the shop (other than my old stick machine). Because it was an auction I ended up buying WAY too many. Im not upside down by any stretch but I have NO idea what these machines are worth. Im in NE Oklahoma (area is booming, oil area). My brother in law owns a fab shop. I told him to pick them up and test them and I would let him keep 2. I ended up with 8 machines to sale. Hopefully I can get a little info and guidance....

What I have are two complete machines. One is an old Miller CP-250TS (3-phase, 460V) on a cart with a single feed Wire Feeder, Old Millermatic. The Feeder is on a separate cart with pretty long leads. They unplugged this machine and rolled it into the auction. The second compete machine is a Miller Deltaweld 452 with a Model 60. It too is a complete machine with the feeder on a seperate cart and long leads. It too was unplugged and rolled into the auction.

On top of that I ended up with 6 other 3-phase welders including more Miller Deltaweld 451, 452, a CP-250-SM with a Boom for the feeder (Model 70 Duel Feeder), and an old CP-250TS with an older Miller feeder. I have a handful of the Model 70's with Duel Feeders. Again, in all, after giving my brother in law 2 for testing and hauling them to his shop, I ended up with 9. Ill keep the only 240V so that leaves me with 8 welders to get rid of an I have NO idea where to start.

Ill probably just list them on Craiglist and take them to a massive auction we have in NE Oklahoma 2 at a time until they are gone but I have no idea of real value. Any suggestions is GREATLY appreciated.

Welcome to the forum :waving: and to be honest there's not much call for most of those power supplies outside of a three-phase industrial setting and conversion to single phase is either impossible or impractical for most folks.

However, the feeders can be used on a host of other machines and WW member/moderator 7A749 (Steve) would be one of the best to comment on what you have and their potential value.

Shoot Steve a PM. He's on.

I priced out the CP-250TS (red Oxide Cart Above) with the Millermatic, leads and all for $1,100.00 today and the Deltaweld 452 with a 60 series single feeder (both on carts), all leads, etc. for $1,800.00. Both of these welders had the bottles pulled, were unplugged, and rolled into the auction and are supposed to be sound welders.

Too much, too cheap? This guy really wanted pricing. I also have another guy from a local refurbish shop wanting to look at the rest.... any ideas?

I have seen price ranges ALL Over the place. Prices are all over the place as well. I have found welders like the CP-200 listed for $1,200-1,800.00 online, and some have sold in those ranges. Again, this is not my forte so I have no idea.

Thanks in advance...

In my experience the 3 phase machines are generally bought at scrap value. Unless of course you have the electricity. The feeders will sell a lot easier if you can clean them up and make them look a bit better. I'd advertise the Deltaweld for best offer and be happy to get $500. It may bring 12 or 1500 you just never know. Check what those are selling for(selling and not asking price) on Ebay if you want a quick guesstimate. Shipping is ignorant on those beasts. Good luck.

Are they all strictly 3 phase machines and not 1&3 phase? I've seen some machines that can wire up both ways by either using or dropping a leg on your input cables. The serial number on a Miller has an alpha date code that designates the year of manufacture.

Thanks for the input gang! This helps greatly... I didnt know where to start. I bought them at a very fair price so there is money to be made, even with the prices listed above.. May take a while to move them though given the 3 phase. Ill have to see what I can do!

They are testing them this week (supposedly) so ill update and let you know how it all pans out. My biggest hope is that once I know the stats on all of these I can just pass them on to a growing shop at one price and save myself the hastle!

Converting the CP200 and CP250 to single phase is possible. I've done it on a CP200 and it welds great, especially with the sturdy wire feeder (10E in my case). I have a 2nd CP200 awaiting conversion and a CP300 which will lag behind because the procedure is not as clear. Both of the ones awaiting single phase conversion have the 30A (dual head) feeder. Dave Kamp helped me do the first one.
