Re: Looking for Opinions

It's hard to beat an engine drive for being able to work in remote locations. Many years ago, I bought a new Bobcat 250. It welds great, powers my Millermatic 210 if needed, and runs my house during these stupid Public Safety Power Shutoffs. It's mounted on a Harbor Freight trailer with a tongue upgrade. Over the years, it's been on two of those, a tool bed trailer, and a base with big casters. The little (40x48" bed) HF trailer isn't showing on the website any more, but many of the stores still have them. I think it's about 1200 lb capacity, carries my Bobcat and my O/A tanks easily. Way less $ than the Miller trailer, and makes moving the machine easy. Weak point is the supplied stamped steel tongue, it's short and weak. I replaced it with a 7' piece of 3" square tubing, and changed to a 2" ball coupler.

If I had to regularly run without power in the shop, I'd get a smaller generator to run the lights and saws. Less gas and less noise. I'd also get a good popup canopy and work outside as much as possible.

Re: Looking for Opinions

Yup may want to consider acquiring and enclosed trailer and setting up your fab shop inside it. That way everything is out of the weather and you can go mobile with it for the side jobs.

Either an engine driven welder or a generator could be installed inside.

Good for the machine itself and a guy can weld quite heavy with modern equipment. Only downside with that might be lack of 120V. Not too long ago we wouldnt have considered a 120V ord out to 100 ft and be able to do general work. They make a machine weighs 15# and runs 1/8 6011 and 3/32 lo hy north of 100 ft cost under 200$ and for another 50$ can get dvi and do 1/8. Even if I was to come up with some other kind of scheme this would be a start ing point if I didnt have squat.

Re: Looking for Opinions

One of the eld timers on the Miller forum lived in a nice place, had a garage was spec built and had 30A service. He was an early adopter of bit smaller machines, I think he has a 210 and small wire and a 375 cutter, worked outside during the day and managed. It was a hobby deal though.
A genset is a poor way to do fab work. Gould fire it incidently to do heavier welding, but cant imagine today not being able to reach something with a common cord, do I really wanna do fab work away from simple line power?

Re: Looking for Opinions

yeah look I got told the same thing, and I'm sure that it's not exactly great for the genset, but yeah I can run my 300 amp mig at 30 volts and 300 amps with .045 dual shield, my 13KVA gen set outputs 12k watt's peak and 11k watts continuous, the numbers for 300 amps and 30 volts are 9k watts, times by the efficiency of the machine which is 84% so the draw at the plug is 10715, which is cutting it pretty tight, but that 12k watts peak output cover's the startup, and I havn't had any problems, I don't tend to run it flat out, more like 27 volts and 250-270 amps which is closer to 8.5k watts wall draw which keeps me well in my gen sets capability.

I also have a 9KVA 7.2Kw single phase generator that runs a lincoln Powercraft 250C MIG, this pic is an 8mm overhead done with Kobelco DW-50 dual shield a 100% CO2 done with that 9kva generator and 250 amp MIG at 26 volts and 360 IPM, this is right at the limit for this generator though.



the 13KVA 3 phase gen set won't run my 270SX with stick at max though, the short circuit at the beginning of a stick weld just stalls the gen set, so 200ish amps with a 5/32 7018 is all it will do with stick, even then the striking the rod is hard on the gen set.

Re: Looking for Opinions

I agree.

And using that to run my welders, a Kemppi Fitweld 300 EVO and now a Lincoln 270SX mostly for carbon arc, but also heavy stick and TIG.

I like to portability of a generator (the one there is only 165kg with 40 liters/10gallons of fuel) and the you are not limited to using the Genset to use a welder like you are with an engine drive, plus it's on wheels so can be pretty easily moved by hand.

Interesting, I've been told you need a 20kva genny to run a 300 amp MIG set properly... even the modern inverters... can you max it out on that genny then?

Re: Looking for Opinions

I always wanna ask,,,, why cant you get power?

Re: Looking for Opinions

I take it is a home shop.
I do not know how close you are to neighbors. But real close a block fence fill with sand keep sound down and insulated ceiling.
Are a long distance from home?

Here's the pickle I'm in.
I don't have a garage to work out of. I do have a 12x16 shed but no electricity to it, and without the possibility of adding power anytime soon.
there are several routes i have thought about going.
Hobart Elite 225- 11,000 amp generator, so i can run a smaller multiprocess welder. That would fix my needs of being mobile and having access to all processes. It would also keep me around $6,000, which is my budget. Cons - would have to get a trailer to tow it since i'm limited on bed space. and i've heard its horrendously loud which is just an inconvenience really not a serious con.
other option is to just get a capable generator and a Multiprocess welder. Maybe a little cheaper. Potentially Smaller footprint? But does it make sense?

What do y'all think?

Re: Looking for Opinions

Welcome!! When not driving your desk go walk around the project your workers are on. Just chit chat with them for short times and move along so they don't feel you're looking over their shoulder. If the Hobart is too loud build a 3 sided enclosure with no roof and with fiberglas insulation with glas facing inside and make it big enough for good cooling air circulation.
