LOTOS CT520D 50 AMP Air Plasma Cutter, 200 AMP Tig and Stick/MMA/ARC Welder 3 in 1 Combo Welding Machine, 5/8 Inch Clean Cut, Brown

Certified welder mig/tig and stick. My honest opinion straight out of the box I was hesitant for how light the whole machine was. No instructions were necessary for installation of hoses, adapters torches etc..for everything is fairly cut and dry. So here are my unbiased opinion(s);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 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 cuttingThe 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.

I am posting this well after buying. I have owned my machine for six months.I like this machine as a good starter TIG machine, decent plasma cutter, and Fantastic Stick machine. Sad that the lead for the stick is so short though. It's just long enough to reach my small table, If I needed to work a bigger project I'd be screwed.As far as TIG goes, I should have just bought an actual full TIG machine now that I have some experience. I need the different settings this machine doesn't allow for in order to produce better welds and get better. The TIG torch is fantastic though. twist head, button control. I love it.I went ahead and bought the pigtail for 110 since I don't have 240 in my house.I was about to Run 240 myself, so I hunted down 6/3 wire, and a 50 amp rated plug, which are very expensive apparently, especially when compared to a 30 amp. Also, special order that will generate a "restocking fee" at the online seller or managers discretion at the big box store of whick represents the online seller should I need to return it. I tested the plug to the welder. It is locking just like the plug, but it doesn't fit. Then I noted the welder plug states 30 amp.The manual clearly says 50a input for this model. it also is unclear in some other information like output. Anyway, I did take the plug apart to see about getting a different plug end type but the colors are not standard (US anyway) so I don't know for certain which is which, Then also, it is really well made plug that has some fancy clear plastic buffering and I didn't care to mess with that.I could have saved over a hundred bucks if the manufacturer had been clear that this takes 30 A. I could have bought 8/3 instead of 6/3 for about 50 less, and gotten a decent plug for anywhere from 40-75 less.Oh well,. Here I go wasting my time returning and repurchasing. I'll probably stick with the 6/3 for when (not if) I upgrade to purely TIG machine from a more mainstream supplier.

La máquina no funcionó. No daba chispa estaba muerta.tuve que devolverla y solicitar reembolso. Es una marca muy mala. Nada recomendada

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.
