I bought one of Miller's, small units, I mean 1/2 the size of a suitcase, cost $900.00, for an Ironworker to use on very detail orientated type project we were working on in '03. Being on the specialty subcontracting side of the fence on this venue, and just one of several complicated projects we were contracted to do, I was the company's senior project manager, and with that responsibility comes finding solutions to problems and or find more efficient ways to get things done to maintain a projects labor budget and or get ahead of the game further as you neve know when you will get snagged on something later. Being a field guy, and spending the majority of my time in the field whenever possible, (and these jobs kept me there daily they were so complex ) also to some of the companies partners dislike ( aaah, whatta they know ? LOL ! ). I had to find a solution for placing a weld on 2" x 2" 1/4" thick washers, to secure them in place, they were part of structural connections for very large ( 4000 lb ea. ) window units we set with a crane. There were a lot of connections and we used this structural connection typically on a lot of our jobs. Buzz boxes are great, but when your running around in high rise building's it's either got to be centrally located and you have to run your cables through the floors, or you need a power source nearby, with other trades drawing power all day, tripping breakers causes delays etc. With all the obstructions and nonsense making sure there was a pigtail for a larger welder, something smaller made more sense, the welds were 1" long. This little Miller unit would allow you to use an 1/8" 7018 electrode, get good penetration on mild A-36 1/4" steel, I tried it out on the job myself, it made a nice strong weld, the duty cycle worked out ok, because the welds were max. 1" long and just 2 per connection. No excuse for a guy not to be productive, he could plug into a 30 amp circuit on a heavy lead and work floor to floor without delay. This unit had a strap, so you can carry it around with you as you work. I just figure I would mention it here, I was impressed, you are not going to make long passes with this welder, we had the heat turned up close to max. ( can't recall the model now ) but anything that could get that kind of penetration and be so small, plug into a 30 amp circuit, was really amazing I thought. It was a labor saving device, being so easy to use, had my foreman give the task to a senior guy, an easy job. All the welds passed inspection, really paid for itself.
