Great running little thing.
I got to say that I really like this little machine. I received it today, got it all put together, fired it up and it worked like a champ. My first piece of steel was some 7/16 inch flat bar and totally went through it like nobodies business. My jaw hit the floor. I do know I need to get one of those wire doohickeys so I can maintain a even distance above the cutting surface, of course that's my issue not the machine. I did a few more cuts on scrap metal and it just worked great. I connected up the stick welder, grabbed 3/32nd 6011 and it just turned it to really smooth butter. I had the machine set to 55 amps and it ran just great. As far as it's operation and considering the fact I'm just a hobbyist, this little box really fits the bill just about right. It's the best bang for the buck for what I do. As for anything negative, there are a couple but they really quite minor. First would be the leads need to be as long as the one used for plasma cutting. The grounding clamp lead definitely needs a little extra length to it. Then in the description of the product itself, and maybe I overlooked it, there was no mention of what type of electrical plug it had. For some reason I was assuming it was coming with no plug and just open wires so you can make it for whatever you needed, 110 or 220 volts. I was somewhat surprise to see that it comes with an L6-30 plug. Thinking I was going to be wiring in a L14-30 I was stumped temporarily while I came up with a solution. Anyway none of this was really a show stopper and not all of it is related to the machine or the manufacturer. This machine is a good running little dude and I'm right now happy that I bought it. Oh and as a side note, I exchanged emails with Mike at PrimeWeld and he really seems to be a good down to earth person. UPDATE: So it's been about 18 months now and I have been using this little machine for a lot for various projects. It still runs and operates now like it did when I first got it. One of the projects I built with this welder is a trailer which goes on the back of an ATV for use in Search and Rescue missions to transport injured people. I added a couple of pictures here for your viewing pleasure. One of the pictures is members of my SAR team for a local parade so we could show it's first preview. This Primeweld machine is the real deal and I have no regrets in having purchased it. It may very well be a product which could contribute to saving a life someday.

WORKS GREAT!!!
WOW It welds, it cuts, I haven't been able to use the TIG yet, but I am VERY PLEASED!!! The first one didn't work, and Mike promptly sent me a new one. I have been looking at these multiprocess units for months now, and after reading all the reviews for the units under 1000.00, I realized that no matter the brand, US or import, they all can and do break at times. So what it comes down to for me is customer service. I read about Mike's responsiveness and decided to test it out, so I called the number, and he actually ANSWERED the phone, he answered all my questions, and assured me of the 3 year warranty with free shipping both ways. I feel like for the price and the great customer support I can't go wrong. I have burned about 30 6011 and 7018 rods in 3/32 and 1/8, Radnor, Lincoln, and Vulcan brands all run just fine. Switching to the plasma cutter is easy, I have cut 1/8 and 3/16 like butter, haven't cut anything thick yet, but I don't have much of a need to cut thick stuff. I cut my teeth years ago on an AC buzz box, and this welder welds 100% better than that old technology!!! The gauge is on the front of the machine AND is in PSI!! (some import units come with gauges NOT in PSI, and at the BACK of the machine, so you have to convert to PSI, and go around the back to see the gauge). All the leads seem to be of good quality. I put this on a HF welder cart, converted the L6-30 plug to a 240v plug that fits my welder outlet. I actually use a 8g 3 conductor 25ft extension cord I got off Amazon to reach around the garage, works well, couldn't build one for much cheaper. I wish I had just bought the adapter that converts the L6-30 to 240v plug. Considering the price and the excellent customer service, I expect your experience would be AT LEAST as good as mine. UPDATE 2/18/19 - I have burned about 60 lbs of rods so far. YES thats 12 of the five lb boxes. I don't use a plasma cutter much, but it always works. I finally changed the tip just to change one. Still works great. Yes I would buy it again

Not bad at all.
It works how it is supposed to. Less expensive to operate than tanks and from my experience cuts straighter. The real question is would I buy it again. Yes. 8/10. Mine didn't come with a plasma cutter guide which is really helpful for fine cutting and you do have to purchase a tig foot controller. Update 9/10. Very usable lightweight machine. The plasma cutter works pretty good and so does the arc welder. Easy to carry around.

Great little unit
I first bought this just for plasma cutting ability. It worked great on my farm projects. Then I had a larger more complex project building arena panels . Used the stick welder then. With digital Amp settings you get easy start arch, and easy tac welds. I found 3/32 worked well on the thinner steel all things are made out of anymore. I hadn't stick welded in 35 years , high school metal shop . This machine made it a easy, quick learning curve with minimal burn thru . Remastered the techniques from metal shop. Only issue I had is after a few jobs with plasma cutting, cutter didn't want to throw cutting arch. Tried every thing. New consumables for torch head, different air compressor, etc nothing made it work. Called prime weld and in taking me thru things I commented that torch head had a Crack in plastic . Sent them a picture in text msg. They said that would cause fail. Emailed me a shipping confirmation of new torch headed to me , for fix. Awesome customer service. And backing their product up. Nice to know there are companies out there still putting the customer first. Haven't tried Mig welding yet. But if it's like the other jobs this machine does I don't think I'll be dissatisfied . Would highly recommend and buy again or buy other products from this company .
