Welder Needed

The OldWizzard1 accept that he's wrong. Dude, you've got a better chance of being hit by a meteor than that ever happening. How long have you been on this board? Two things you can always count on besides death and taxes:
1) He's cheap.
2) He will never admit he's wrong.

Part of the discussion is to correct bad info when we find it so that people who don’t know any better won’t get bad advice.

***** that some people dig their heels in but that’s part of the deal on a free public forum I guess.

I guess I have been mistaken about that. I was under the impression they had some interchangeable parts, not all but some.

Feeder wheels on the MIGs, plastic vs steel

dont even come out of the same factory. just owned by the same parent company

There is definitely some part swapping going on. Doesn't mean they are from the same assembly line but the Miller parts bins are certainly raided to varying degrees.

The digital readout is definitely worth whatever extra money Miller is charging over the Hobart. It makes it easy to follow a parameter chart.

Very unusual unless the house was built to your specs.

Nope, it was a builder spec home. That’s how they did all of them.

The one plug in the garage was annoying but I added a second circuit and more outlets for a total of 15 20 amp receptacles. It’s way gooder now

Not sure when that started. The 187 I have has steel feed wheels.

It’s one of those internet legends that refuses to die….

There were threads on the Miller forum about swapping them, it's not all models, just some apparently.

Electrical devices have come a long way in 50 years. It seems like I’m so many of these posts you’re still stuck in the 1960s.

Welders in particular are primarily inverter based machines now and use computers and fairly advanced circuitry to achieve the desired welding output on a given input power. I don’t pretend to know how they work but the electrical engineers at Miller and whoever clearly know what they’re doing.

I’ve run my Maxstar off 15A household circuits in MANY homes doing railing installations. The only time I pop a breaker is if I try to run above about 130-140 amps or so or if I long arc too bad and the voltage spikes to maintain the arc. And that’s a 15 amp circuit in someone’s house, not a dedicated home run in a garage.

My Invision 450 mPa can run up to 600 amps output on a 35 amp 480v breaker. I don’t know how Miller does it, but it does it. I’ve never popped a breaker even running 1/16” aluminum wire MIG welding 1” thick plate.

Inverter welders have changed the world in terms of power requirements for welders.

@dr_clyde

Are these railings, like handrails/guardrail projects?

I've designed some stairs and railings for commerical jobs. I usually see engine driven welders on the job sites, especially if there's structural steel on the project (which usually the case.)

Last project was a new mezzanine with steel composite floor, some marquee storefront with exposed structural steel and skylights. It was a good sized mezzanine project inside a pre engineered metal building. Think: Lipstick on a Pig, LOL. We got sucked into designing the stairs, handrails, guardrails and all that... scope creep...but we paid for additional services.

1) FRUGAL !
2) I thought I just did !

An engine drive is best if you can run it, but some places I can’t get leads or access, or sometimes the extra power, noise, fuel consumption and expense isn’t necessary.

I occasionally have to fit up or do position welds in finished homes or offices, can’t do anything that makes sparks so a TIG machine that I can plug in anywhere is just the ticket.

No it isn't. Code requiring derating by 20% for constant loads, which a welder is not. You can use the full 20a. and then some, depending on how long it runs for.

Only for continuous loads.

I understand that, and should have been more specific when stating I "assumed" that is what he was thinking when he stated that load. Most people assume that is gospel.
