Great running little thing.
5 Stars
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.
Thank you for your feedback
