YESWELDER 200A AC/DC Aluminum Tig Welder with Pulse, Digital Inverter STICK/TIG 110/220V Dual Voltage TIG Welding Machine TIG-200P ACDC

Amazing little machine for the price. Works extremely well for it's size, however the low amperage AC tig has issues triggering even the most expensive helmets. I've tried 5 different helmets ranging from Amazon brand all the way up to a Miller and it has the same problem. Just be careful with low amperage AC tig because you might get flashed accidentally unless you have a REALLY expensive helmet like a 3M Speeglas or equivalent.

So I am new to Tig. The advertisement of "Aluminum tig welder" for the square wave sold me. However, you don't need it to weld aluminum. I wish I knew that before I purchased it . I did however find using a foot pedal to control the heat makes things way easier. I purchased the yeswelder 5 pin foot pedal as well. I have been practicing for only a few hours. Took a while to understand how hot is too hot. I watched a bunch of videos online and found out having a pedal is the only way to go if you are learning. I used 3/32 blue tungsten at first and I ended up going to 1/8 for easier use. It's hard going from flux core MiG to Tig. Tig requires you to keep the arc at a specific height and don't pull the torch away like MiG. It's fun to learn new things! Way worth the challenge for sure. Will I be a pro? No. But I learned something and can add a new ability to my garage. Welder pros: This welder has a lot of features like adjustable upslope, downslope and frequency along with square wave, balance, pre flow and post flow. Much more than I'd ever need. Welding some aluminum plate, I was able to do some basic start and stop exercising and really trying to learn how to control my hand. The welder really is amazing. You really need to understand the process of it and just play around with it. For amps, I started off too high. Frequency I started off too low. My post flow wasn't long enoughh. After realizing I was burning through the aluminum I lowered the amps to about 50 and then I was able to not burn through. Again, controlling it with the foot pedal is best because you can see the weld pool and adjust your foot and cool it down or heat it up. My settings for 1/8 aluminum (AC) 60 amps ( max, controlled by pedal) Pre flow .5 Frequency 120 Post flow 5.5 Tungsten 3/32 blue Argon 15 CFH #8 gas diffuser The frequency is cool. You can tighten up the arc cone and make the arc really tight or smaller with a higher frequency. Really cool! Overall I'm pretty happy with this machine. I hope it lasts. Cons: The manual. No settings guide other than titanium. It doesn't even explain what each of the settings do. Just basic definition of the settings. I don't like how large to torch is. It is huge, like a MiG torch. Also the torch is an all in one. No separate line for the lead and gas. *I ordered a different torch and new hose. It is way better than the one that comes with the machine. I don't like the cheap push buttons for the various settings. I wish it had an LCD like other machines. It didn't come with a gas regulator. It didn't come with any tungsten.

Weather your a beginner or a professional welder this machine is a great choice especially at this price point I also bought the foot pedal to go with it. I needed an extra machine for an aluminum tig job I had coming up and this thing was fantastic for 1/8 th I did som 1/4 with it as well it’s only a 200 amp machine but it’s great. I recommend to anyone looking to get started tig welding it’s easy to set up and use. And has a lot of features for the price.

I have used this machine with on stick mode and it works great. However, it will not run at all with the 120 adapter. It sparks, but it just doesn't seem to give the machine enough power. On 240, it works great. I can't speak on the TIG settings because I haven't had a chance to get any argon. As a welder by trade, it's definitely good for the price

This thing is awesome
