200A TIG Welder with Pulse, 110V/220V Dual Voltage, 3 in 1 DC TIG/Pulse TIG/SPOT TIG/Stick Welding Machine, Digital Screen Display, Over Loading Protection

Absolutely love this machine. It performs well for Tig and stick. I've done aluminum, cast iron, stainless steel and mild steel with this machine and it has done me great so far. I've put about 1000hrs on it so far. There are only 2 issues I will mention...1. I have tried a few different 5 pin pedals and can't seem to get it to work with a pedal so I just use the trigger on the torch....2. the part where you connect the gas line comes loose so you have to use 2 wrenches to disconnect the gas line which is kind of inconvenient. All in all, for the price of a 250amp acdc high frequency Tig machine, you can't beat it.

This was recommended to me by an iron worker that I work with. He builds small aluminum jet river boats with this welded amongst many other projects. His projects that I’ve seen besides the boats are, gas tanks, manifolds, and handrails. I bought this welder for my son. It not only is a great TIG welder, but a very smooth stick welder. Definitely a good buy!

This welder is decent for the price. The only thing is that it tops out at 100hz which is not what i prefer especially when welding thinner aluminum but it still puts down a decent weld.

I figured I would gamble on this since it was so much cheaper than every other one. It works great so far. I have a tiny bit of MIG welding experience and no TIG experience. I struggled day one but found a good video that got me going smoothly on day two on 1/8 and 1/16 aluminum. I definitely need practice but I don't think the machine is holding me back. I also order the pedal, a gas regulator, and initially forgot tungsten. As others have said the directions are very limited but there are good reference websites you can get tig settings from. It was a bit overwhelming with how many settings there were until I learned that most don't matter if you have a foot pedal. Overall I'm super happy with it. One other review mentions measuring the output but based on some reading that is often limited by the torch you get. A few of the better known brands with 200+amp welders had information about their torches and most were limited to around 150amp. My understanding is that much above that you need a liquid cooled torch. Anyway I think it's a great buy if you want to dip your toe in or just have a couple small projects. I'll update my review if anything changes.

Doesn't put out the advertised amperage. As soon as I struck an arc, I could tell something was off, so I grabbed my clamp meter to see if I was just imagining things. When I put the meter on it, the actual max amperage read to only be 162a (see pic). I tested this on both the ground clamp lead as well as the torch lead, and got the same result both times. 162a is nowhere even close to the 250a that is advertised on this thing. Just to be sure, I also tested both with a pedal (from another tig welder) fully depressed and without a pedal (using the switch on the torch) and got the same result 162a each time. Other things I noticed: The frequency setting maxes out at only100Hz, whuch is rather limiting to say the least. The icons on the screen are rather small and hard to read making it difficult to do any quick adjustments without getting up close and personal. Btw, I checked the amperage using the same meter on a different brand 200a ac tig welder just to eliminate the meter as the culprit, and it read nearly the full 200a as advertised, so I know its not an issue with the meter.

I think for a cheap machine it has a lot of higher end options. I only purchased it for the capability of aluminum tig welding. I have a spool gun on my other machine but I have a lot of jobs come up where a spool gun just won’t work. I like that it’s small and light enough to carry around if needed. I mainly bought this one over others because it has a push button gun. I was pleasantly surprised at the length of the tig lead. Make sure to buy the extra adapter they recommend in the description so you can use the supplied tig lead and have it work correctly. I thought I could just plug it in since the connections matched but it wouldn’t start an arc or purge the gas and kept flashing a foot pedal image on the main screen. Something about that little adapter makes it work for the button gun. Pros- long tig lead, lightweight machine, easy to use, user friendly screen. Cons- included instructions are useless, ground is a little shorter than I’d like.

This welder does everything rly well, I've regularly used 240amps ac to weld aluminum and it has never overheated or slowed down after use. I have been using it for almost a year now and I personally think its better than other much more expensive welders out there. The baja team I weld for has their own very expensive tig welder that I use, which maxes at 210 amps and doesn't have full control over a lot of things as it trys to set them for you. This welder does everything you ask it and does it perfectly. It also does all this while being super portable. The only weakness this welding machine has is thin aluminum as the maximum frequency it can do is 100, with skill you can still do it. The only reason I'd ever replace this welder is if I want water cooling or more higher frequency settings. I will also say I did get a pedal and replace a lot of the stuff it comes with, but the welder itself is the best welder I've ever used

Im completely new to tig welding so i have no way to copare this welder to anything else BUT it seems that the performance is as advertised. The manual it comes with is almost worthless, doesnt really explain anything about how to set it up for what you want to do. It only gives you some example settings to go by for each type of welding it can perform. Im still playing with the settings but ive manged to weld some 3/8" aluminum plate with the current set pretty close to max and the weld looks decent for someone who has about 15 minutes of tig welding experience. The only thing i dont like so far is the ridiculous power cord that is an anemic 12AWG cord with this big 50A plug on the end that is completely unnecessary. I opened it up and replaced the cord with a much longer true 12awg copper wire cord and more reasonable 20 amp 240v plug and it runs just fine on a 20 amp 240v circuit without tripping the breaker
