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.

Sunstac did it again! Let me start this review by saying I’ve been welding for 20 years now professionally and I’ve got to say I’ve never been more impressed by a company that can put out machines like this at this price point. Quick backstory, I bought the 5-1 MiG tig plasma machine a few months ago from sunstac and was honestly hoping it would last one job to get me through it. Fear not, it’s paid for itself 100 times already. My only kicker with it is it didn’t do ac tig. I was so impressed with the other unit (that I’m still using everyday) that I had to get a matching ac tig machine and I’m glad I did. This little machine pumps some amperage out. It will weld 1/4 aluminum no questions asked (220v). I run both of my sunstacs off of my miller trailblazer which has a 10k generator built into it (50amp output). If you’re wondering if a 10k generator will run this machine the answer is yes, I absolutely can confirm that it will do its job with a 50amp 220 output generator that producing 10k watts or greater. Pros- -for its price point it’s fairly adjustable - light weight and mobile - build quality is quite good, I’ve taken it apart to check if everything was secured and tight inside and everything was great. -35-50 dinse connectors make everything quick and easy to break down and put together. - versatile settings ac/dc tig with pulse and spot weld feature Cons- - the ground cable is on the shorter side, this doesn’t effect me since I am equipped with my own leads but keep that in mind if you’re planning on doing work far away from the machine. - the torch does get quite hot rather quickly when welding heavier material. This is completely normal for an air cooled setup but does need to be mentioned for people that may not have as much experience. I am planning on retro fitting a water cooler to the machine which after taking it apart will be extremely easy to do. Keep this in mind if you’re planning on welding heavy material for a longer period of time. Though I have not been able to make the machine trip into thermal protection even welding thicker material, it does get quite uncomfortable. Summary If I could give this machine more stars I absolutely would at this price point and how efficient it is the home hobbyist will absolutely not be disappointed at all. I use this thing to make money and thus far is been a great addition to my equipment. Bravo sunstac hats off to you for making a great machine. I love it so much I might buy another one just to have a back up machine.

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.

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.

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.

Great welder ! Used this for my company , we do a lot of sanitary stainless and aluminum/ I got to use this out for some structural code 7018 stick welding and it ran flawlessly. I’m hoping to get some great deals or opportunities to try some other machines of yours to review ! Will update with better reviews too

Buen producto, casi un año trabajando y todo OK. Solo en proceso de Stick , tengo que probarla en TIG

La soudeuse fonctionne très bien avec le tig autant en AC qu,en DC et elle a beaucoup d,ajustement comme AC balance et AC frequence , j,ai acheté la pédale tooliom #TL-FP-5P et elle fonctionne très bien avec cette soudeuse pour varier l,amperage. Le régulateur de gaz n,est pas inclus seulement le boyau.

Ne fonctionne pas. Il y a juste l'écran d'affichage qui fonctionnent. Le ventilateur ne fonctionne pas à l'arrière semble avoir un problème électrique à l'intérieur. J'ai envoyé un courriel au vendeur j'attends des nouvelles. Si tout va bien avec le vendeur. Je vais changer les étoiles .

Tengo 4 meses con ella, su relación precio calidad me parece razonablemente buena, buena para soldar aluminio, constantemente tiene problemas para estabilizar el arco en AC y AC Pulsado, en muchas ocasiones pese a que presionas para iniciar el arco, ya sea con la pistola o con pedal, el arco no se inicia y se escucha un zumbido en la máquina, otro problema que veo es que el amperaje de salida no es el nominal de la pantalla, así que realmente el ajuste debes realizarlo viendo y evaluando la formación del charco, al inicio la máquina operaba mejor, pero realmente la he usado unas 5 veces posiblemente, si el objetivo es para trabajar más frecuentemente, creo que podría no ser la elección correcta, no hay pagina ni teléfonos de soporte mucho menos garantía

It seems to be a good machine, it works very well, I hope it doesn't break down so soon.
