    Newbie question: Mystery welder

    Hello everyone. I am a very inexperienced welder but I am eager to learn to be more proficient! That being said I know very little. I was recently given a 220V Arc/Tig machine. I was told it was a german preproduction model. It has absolutely no markings or brand names anywhere inside or outside. I have the arc welding leads but I would like to get the Tig leads for it. I already have an argon setup waiting to attach. I attached a photo pf the front plate and if necessary I can pull it out and get outside/inside shots of the rig. Can anyone identify it or what setup I would need to complete the tig setup? Im assuming from the front plate it is a scratch start setup? It also has a wiring diagram on the inside cover if that would help identify it. Thanks guys for the advice ahead of time! The metal and hose in front of the welder is the motor being rebuilt for my Samurai Crawler project!

    Yeah,

    Interesting!

    It looks like it may not have a gas solenoid for TIG. But there is what looks like a remote outlet plug for a pedal or contactor switch, which may mean that it could have a high frequency TIG start ability. And a foot pedal will take a 5-wire plug, at a minimum.

    Is there a gas inlet barb or fitting at the back of the machine?

    If not, you'd need a TIG torch with a gas valve on it, which are easy to find.

    Have you struck an arc with the Stick leads to ensure it functions?

    It goes to 400 amps? Is it a 3 phase machine?

    As mentioned by C Livingstone; you probly need a torch with a valve. A close up of the remote connector might help identify the connector you need for remote use but you could use it as a scratch start in SMAW mode.

    How about ESAB LHF 400? 3-phase, requires 400-550V power. (EDIT: For some other markets, maybe 220 or higher.)

    Oh,

    It's a match!

    The ESAB literature, doesn't give much information, but does state an optional HF box was available, not that I'd try to look for one today.

    So, is yours 1-phase, 220 volt, unlike the ESAB branded ones?

    Hopefully the wiring diagram on the inside cover will show the proper connections for power. I seriously doubt that it is a single-phase unit.

    Yeah,

    I'm guessing it's not either.

    I mean, if it is, it would undoubtedly have to be a high-amp 220-240 volt circuit, with a fat cord to output 400 amps. But, most things electrical are above my so-called pay grade.

    You guys are awesome!! I have not run it since it is missing the connector on the power cord. I haven't wanted to plug it in or run it without knowing exactly what it is I have.Name:  IMG_0059.JPG

    Well, then,

    It's probably an 3-phase unit, which probably has little value to you as an resididual use TIG unit.

    It's undoubtedly more of a liability, than an asset, then!

    Re: Newbie question: Mystery welder

    After looking at the wiring schematic closer I can see it is 3 phase. Unfortunately it will now just be taking up precious garage floor space! But thank you guys so much for the help! I can see now why this is the best welding forum on the inter-webs!
