Excellent machine for the money
I have worked in the industrial maintenance field for 30 years and have a shop at home. I was really wanting a plasma cutter for home and was searching the internet and found this machine. The reviews were mixed but for the price I thought I would give it a chance. All I can say is WOW. It has paid for itself over the years! I have used it now for 3 years and have no complaints. As a plasma cutter it is as nice as the hypertherm I have at work. I have had no problems cutting up to 3/8" steel with it. The leads are a good length and can handle a lot of cutting The arc feature works good too. The duty cycle is a little low for big, high power jobs but it works great! The tig feature works great for small jobs. There is some limitations to this machine... it only really works good when running 220v, it works ok at 110v but really doesn't have the punch to do much work. The arc leads are small, short and not made for a lot of work. Overall it has been one of the best investments in tools i have ever made. If it died tomorrow I wouldn't be upset. Update- 5 years now and it still works great! It has hundreds of hours on it and still good a new! Great machine for home shop or farm! I have ran this with my portable generator for field repairs and it works great!!!

I'm sure it's pretty far below a professional machine but the versatility is perfect for a DIY'er.
Purchased in 2021 and it's now 2025 so thought I'd give it a review. I have now used every feature that this machine offers. I have stick welded, TIG welded (with gas) and plasma cut. It has done all 3 surprisingly well. I am no professional welder but everything I have worked on has managed to stay together and it has included attachments for my camper van and implements for my tractor so I have tested it pretty thuroughly I think. At the end of the day, I think this machine has been WELL worth the money and would recommend it to any of my close friends if they were looking for something like this that was versitile and easy to use. TLDR: I've had it for 4 years now and have used it a fair bit. I am very pleased with my purchase.

Good Armature Welder
I purchased this welder/plasma cutter about 4 years ago and since then it's done what I need it to. I am an armature maker so it gets used for a whole day about once a month. While the manual was a little light on details, the welder was easy enough to figure out (it was not my first time with a TIG). I had trouble using the plasma cutter. It was my first time using one, so that might be the issue tho. In case you're struggling there, start with low amperage (8 amps) and lower air pressure (30 psi) and go up on them until you're cutting through the material. If you start with either too high, the machine may abruptly shut off. The welder is all that I need it to be. I've made consistent, strong welds with it. The max of 200 amps is more than I need. I mostly work with 16g steal tubes, but I've also welded 3/8 steal as well. As mentioned earlier, this welder has been working for me for 4 years without any significant issues except for some small things noted later below. I purchased a foot pedal which should come with the tool, if you ask me, as that's the only way to modulate the power while welding. I've used it on a standard 120V outlet and a 240V dryer outlet. It is much happier on the 240V; that's the only way to get higher amperages (100 plus I think) and the electroncs just seem to work better there too. Additionally, after using it on the 240V for the first time the mode selector switch stopped working on 120V. It needs a lot of persausion to switch off of plasma cutter mode at 120V now, of it will even do it at all. I only use it with 240V now but I could see this being a big issue for others. Another complaint is the shortness of the ground cable. At about 4 feet, I have to move the welder pretty close to what I'm doing, which can be annoying. I've not tried the stick welder so I can't report on that. All in all, it feels like they went cheep on the unimportant things and made sure the important things work as they should. I would buy this again and expect simple but reliable functionality.

Nice machine and accessories
I agree with the reviewer that said something to the effect of quality where you want it to be.

Despues de la compra estaba un poco preocupado por mi opcion de adquirir esta soldadora/cortadora plasma. Asi que me dedique a investigar acerca de la marca y quede muy impresionado con los servicios que tienen. En cuanto llego puse manos a la obra y ensamble las partes necesarias para soldar con arco, cortar con plasma y el tig. Una excelente opcion para aquellos que no somos soldadores profesionales pero que necesitamos una planta pequeña eficiente y confiable que haga el trabajo necesario. Ampliamente recomendable.
