    generators and welders

    So I need to bigger power source, period. That's expensive. Figures.

My machine options are a lincoln 140c or my maxstar 150sth. I'd absolutely prefer my maxstar, just not certain if I could damage it by running it on a generator. My power source will be a small, 2000w honda inverter generator.

    So...advice please?
    When I asked miller tech, they told me the maxstar will run off any normal 5000 watt generator. It ran great off my old Generac 5000/6250 genny, transformer based mig welders did not.

    The maxstar is power factor corrected (PFC) and does not require a low THD (total harmonic distortion) generator.

    My HTP 221 isn't the DV model. Never figured I'd need 120v with AC capacity. And really, anything aluminum that were to fail on this car during the trip would either be absolutely catastrophic or we'd be able to build a work around I think.

    My other option on hand is my lincoln 140c (that I could run a spoolgun on), but I'm pretty sure that thing will take even more power to run. This isn't a bad option, and given an adequate power source, it may work well. The missing link is the power source I think. At least for my two welder options.

Didn't cause any damage to the electronics (that I know of), but it doesn't do any good if it doesn't work. And with all the fancy schmancy electronics in these inverter welders, and how expensive they are, it terrifies me to screw one of them up.

    The RV cord is a great idea and once you start looking for power sources in the field, you're absolutely right, they are not terribly hard to find. BUT it won't help me much under an overpass on the freeway. So even if I take along a shore power cord big enough to run something like my 221, I'd still want that portable welding ability. We'll have the generator to run power tools anyway, so it's a matter of multitasking the power source, welder and other tools.
    If you have the 221 DV, it might run from a standard generator. I say this because it has a very robust PFC circuit that sometimes withstands "dirty power". You might want to call HTP to verify if it can work with a standard non-inverter generator that usually doesn't fall in the "less than 5% THD" category. Either way, you need hefty power if you plan to do aluminum repairs in the field as I'm sure you know it needs hefty power at the start to overcome the heat-sinking ability of aluminum. At 120V/20A, you're limited to about 130A of welding power, which isn't much when dealing with aluminum.

    Always pushing the limits is how we get better.

    A phenomena not uncommon in hotrodders & racers as a class...
    I worked at Dave Kent's "Creative Car Craft" during the 1970s and saw "Many" interesting things...

    Took the time to look up and read the rules....

    Holy cow..!!! they sure narrow your options for cooperation and resource sharing....

    Now I have a much better understanding of the limitations...

    I had no idea.. But now fully understand why they are written the way they are...

    I remember looking at those things back in the 90s! Anyone every use one?

    I have to have power anyway, so it's a matter of matching my welding capabilities to my power source and not frying my welder at the same time. I wish I had a nice big bobcat or trailblazer, but that's out of the question...but speaking of those, what's the chance that miller starts making those machine with inverter generators soon? Or maybe they already do? I'm sort of in the market for one anyway; being in hurricane alley and all, a backup generator for house would be nice.

    Anyone else in the group have a Honda 2000? You can parallel them with the simple banana plug kit.

    That will definitely work and allow for 20amp continuos draw.

    Oh.... And don't forget to throw some duct-tape.... 5-MinEpoxy...RTV(Silicon Rubber) and Ty-Wraps into your emergency kit...
