View Full Version : Esab Welder
07-20-2007, 01:35 AM
Im doing a little research for my girl friend who's dad was an amazing welder. He had passed due to cancer and they were looking to sell one of his welders. It is an esab Multi process but the only part numbers i could pull off of it was DTU300 right off of the front. I was considering buying it from them but i was wondering if anyone had any information on it as far as if it is 220V or 440v and anything other information that you guys may have. I know it has the tig and arc capabilities but i was wondering if it also has the provisions for mig welding. I haven't been able to look at it closely. Last, I was wondering if anyone would know the value of it with all of it's accessories. Thanks for all of your help.

It's odd that there is not a sticker/plate on the back showing the electrical input and output ratings.

OK, I am going to [B]***[B]ume the machine is an inverter. 300 amp output. I agree with pulser, should be a tag showing what it draws and puts out at what voltage and duty cycle. I have an invertec 350 multiprocess inverter. 425 amps CC or 45 volts CV. I can even get an optional gas through the negative output terminal for TIG. I bought the foot pedal. It does do it all. Gouges like crazy too. This weighs 80 something pounds. What does yours weigh. It sounds like its not that old. I don't know the original cost but I am pretty sure it was more than $2,000.00
Pics would be great as always.

hey guys sorry it took so long to get back to you. I haven't been able to look at the back it's a huge welder and i have to roll it out. Ill double check and get some pics of it. He had a welding shop. rough dimentions are about 3 feet wide 4.5 long and about 3.5 ft tall on the cart. it has to weigh a couple of hundred pounds. As for age it's got to be at least 15 years old. But it does tig and Arc I found the pedal for tig today. I will definetly get pics though thanks for all of your help.

My previous employer bought a Multimaster 260, mig, tig and stick. We had no use for the tig but the rest of it worked very well. It was the first cv\cc package I'd ever seen. I can't vouch for other ESAB products, but this one made me look like a better weldor than I am.:drinkup:
I could come up with a DTA300 invertig doing a google search. Could that be the model?
I searched google and esab for the model. I also came up with the DTA300. It does say DTU on the welder though. I think because of it's age Im having so much trouble finding info on it. But thanks for the help.

I might be an older ESAB unit that is NOT an inverter if it's old and the serial plate is gone. It's probably a big old single phase tig welder. If I remember correctly ESAB used to be Linde, or somebody like that...They made lots of big tig welders and an older shop is the most likely place to find one still in use. If you can pick it up and it's a 300 amp machine, it's an inverter. If you wouldn't even try to pick it up...it's probably not an inverter. If it's an old big transformer machine, it's probably not worth too much in pretty good shape, it's hard to say...some folks pay quite a bit for some older millers. Big-heavy tig welders run off really large breakers, though...these breakers can be pretty expensive themselves. That one (of many) big advantages of an inverter...smaller breakers...oh, and inverters weigh much less also.
