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.
Cons: I didn’t care much for the 30 amp twist connect prong plug at the end of the whip. I removed this and added a 50 amp 3 pole connector. (Lincoln plug) no big deal just didn’t fit my shop outlets. Second, I didn’t care for the 1/4” hose barb adapter on the rear for your comp air and argon connection. I removed this and added a 1-4 male npt threaded adapter and also installed two ball valves on a tee for faster air to argon change over. Then I put quick connect air chuks coming out of the ball balves. Attached an air chuck to the provided hose for the argon(which I cut down and use my 500psi fire rated air hose mainly for the plasma cutter). No big deals really just suites my faster paced commercial worksite in the shop. Not being negative towards these things but wasn’t my preference so no loss of starts there. Thirdly, the argon gauge worked perfectly but is a bit soft and on the cheaper side l. I get this due to the amazing low price of this machin so no biggie. I used my own gauge and regulator. Again, nothing wrong w product just not my preference. Lastly, I don’t like how you have to run the argon gas thru the machine and use the setup provided. I have my own tig rig that I clamp my stinger to and run argon directly from bottle to torch. No big deal after a bit of brainstorming I came up with a fix to use my rig. No big deal the factory tig set worked great I just like my stuff better. So No negatives really just a preference type opinion.
Pros: First, ( I only run 220 on all my machines. Won’t use the 110 adapter unless I truly have to-not provided)I fired up the arc welder and burned 3- 7018 3/32 rods. They went smooth and good bead. The machine was quit and didn’t sound like a Harley but more like a Vespa scooter. None the less it burned fine. Then I fired up the TIG setup, and keep in mind I used all the factory components first, the button on the torch is a bit different but the high frequency start worked 100%. Very nice. The amp gauge was a bit tricky. Either too hot or not enough, will need to play a it more. Otherwise the tig worked perfect as did the arc welding. The plasma cutter cane next and I layed out a piece of 3/16 diamond plate 4 ‘ long by 2’wide. I cut thru the 2’ side in about 25 seconds. A bit of slag on bottom and had to hit a few places twice but if you go slow, like you’re supposed to, it left a nice clean top surface and cut thru it like warm butter. I sliced thru the 4’ side in about 45-55 seconds. Never phased the tip or cullet whatsoever. You need plenty of good air pressure but unit and component work flawlessly. Overall I am 100% percent satisfied with this machine. Not one single problem or glitch to contend with and for that I’m giving it a 5 Star. Would buy again and would recommend. Hope this helps and good luck
I work as a fabricator, primarily making food safe machine parts for oil extraction (welding was a rather notable void in my resume). I have bought many tools and machines from many companies. In my opinion, the most inportant metrics of a company are that the machine performs without issue, and that the company treats you well when it does not perform. I have currently had to contact lotos twice with minor issues, and have been astounded with the quality of their customer support. The first issue was a misprint in the instruction manual when first setting up (it was using pictures from an older version of the welder that still had seperate imputs for compresed air and argon. dont know why they changed that). All i wanted was clarification, and they responded within the hour and, completely unsolicited, sent me a pack of cutter acessories to make up for the confusion. The second issue was the gas release valve tended to leak at low pressure, which did not effect performance at all but was annoying. They sent me a replacement promptly free of charge. I honestly consider Lotos to have the best customer support I have ever dealt with. If i need another welder or similar tool, Lotos will be the first company i look towards.
In short, this is a great machine from a wonderful company that will treat you well. Do yourself a favor and buy this machine
