Get quotes from three different fabricators. Hopefully, you give them a lot more info about what you need than you gave us. -
Hobart now has them make their stuff, anyway. I bypassed the middle man and just bought my new plasma cutter directly from Harbor Freight. That said, HF has stepped UP their game.Leave a comment:

The days of the EconoTIG are gone. My guess is Hobart will leave the competitive field of aluminum welding to the fancy machines in the Miller line.Leave a comment:

It probably depends on if the cord is part of the Listed assembly, or if it is field-installed....Leave a comment:

I can't read any of the likely useful info in the pic. The most useful info may be on a data plate, often located on the back.Leave a comment:

Again, I do not know what might be required by whatever code the welder maker has to follow. But the NEC stops at the cord and would be silent about what's inside the Listed connected equipment. UL may have something to say on the matter.
I've worked on lots of different kinds of equipment...Leave a comment:

The disconnect on the wall supplying equipment would definitely open all ungrounded conductors. But the switch on the machine doesn't need to.Leave a comment:

I didn't want to count all the f'ing farmers. Ha ha ha.

I've only been an electrician for 30 years. But one of my best friends is an electrician and former plans examiner for this very large metropolitan county and is a Code writer for the NEC. He has UL on speed-dial, and vice-versa! His 1-acre back yard is a testing laboratory for NEC proposals.

For some reason I can't access the manual to that one yet. Worst case, you don't lose enough gas to worry about it. Most of us have been changing out wire spools for decades without that feature.Leave a comment:

My guess is that it is forming at the end from the still-molten puddle losing shielding gas coverage as soon as the trigger is released to stop feeding wire. Unfortunately, most small machines don't have a post-flow setting to allow you to set it for a few more seconds of gas coverage....Leave a comment:

There's gotta be a reason there's no torch with it to make it testable. I'd be leery. What's the going rate for known working ones?Leave a comment:

Thank you for that graph. I edited my post because it's easy to see now it's not exactly "opposite amplitude" but that specific shift gives you a much more constant 90 degrees difference through much of the waveform, instead of a 180-0-180.Leave a comment:

I missed this, but want to clarify that situation, even though it no longer applies to your machine. There is such a thing as 2-phase power, but you'll never see it. For all practical purposes, electrical service is either single-phase, or 3-phase. Whether you use 120V or 240V in your residential equipment,...Last edited by MAC702; 01-07-2021, 12:31 PM.Leave a comment:

Actually, if a circuit is run in metallic conduit, the conduit is a better grounding conductor than the green wire that becomes optional. But I know that's not what you're talking about. Yes, we would much prefer a real electrical path to the panel, preferably run with the power conductors....Leave a comment:

It won't be the National Electric Code. I don't know what Code is followed by the manufacturers.Leave a comment:

I'd elaborate more if I was training an electrician, and thought he was describing an older 2-wire circuit with no grounding conductor. But you do make a very good point about using a GFCI receptacle if there is no way to properly get a grounding wire added to the circuit. While some equipment needs...Leave a comment:

Have you been through the full Troubleshooting section on pages 26-30 of your manual?
Where is your nearest Hobart center? It should be under warranty.Leave a comment:

Those switches can go bad, but usually one position, not all but one. I've had to replace the switch in my Hobart Handler 210 for that reason while it was still under warranty. Use a meter set for continuity (even an automotive continuity probe will work) to see that it can feed through each setting....Leave a comment:

Unless your equipment grounding conductor goes directly to the neutral buss of your service panel or grounding buss of a subpanel, you need to do a resistance test of whatever "building steel" or metallic plumbing you think you have access to to make sure it is a low-resistance path back to...Leave a comment:
