S7 200A TIG Welder with DC TIG and Stick Welding

I'm surprised at how well this little guy operates, many people complimented it, and I confirm they were right

Why would you ever buy the max star. Hand trigger works great for out of position thin stainless tubing. Got a longer lead ground for feild work. Been welding stainless steel for 9 years and this is perfect for me. Can’t believe high end companies don’t use these. 95 degrees outside in ca and no overheating, dragged through rain and mud and welds are still gold. For a long stainless passes I have never exceeded duty cycle however the torch will get hot. Save your money and buy this. Most of welding is electrode set up anyways. Thank you s7 I have made my family lots of money without the expensive get up of larger companies.

Overall a great unit for the money. The leads are probably the only bad part. I purchased this S7 unit February of 2022 and it finally died on me yesterday. It was not commercially used. But as a DIY guy that does a few, larger projects. (3-4 projects a year. Welding 3-4 days each time for about 6 hours a day.) Its hard to say why this one died, because it actually died while I was using a grinder- not while welding. So for $100 its worth the money. Produces smooth, good quality welds if set right and if Welder properly. Im not a professional, but have been welding long enough to figure it out, but not long enough to get a consistent weld with every string. I did use it up to 1/8" rod on 3/16" material. I did not get to try out the Tig function due to no tank.

Works well. Tig works good and stick welds good as well. Small and compact but packs a punch. Recommend for a home user that wants to learn or just have a good welder at home that doesn't take up much space.

Overall it works, the only feedback here and is not documented anywhere. The gas port is a push on nozzle, so I had to cut off the end of the gas gauge screw on fitting, heat up the tube and press it on. Not sure why they don't make a screw on. The pedal and torch trigger is off/on, not variable to control amps. But can't expect that for the price. The instructions are very poor. If you aren't familar with welding already, you may find it tough to follow along. There are very few youtube videos on this. The pros - It has a post gas dial for x seconds of gas flow. This is great. The price is amazing. It also does stick. For the price and doing small jobs with steel up to 16 gauge, up to 1/8 or 3/16 possibly (non structural) this is a great welder. Note: You will need to buy a bottle and fill it at your local gas welder supply. Plan on at least another $250 for the bottle, and $80 for it to be filled. So a bit of upfront cost.

Some learning curve expected, wish the cables where longer

Using the tig function to weld a rollcage. Machine has plenty of power. A little too much power for the tig torch. Unit is rated at 85% duty cycle which was very surprising. I was only using at maybe 20% and I started smelling burning rubber or plastic. I found that it was the smoke coming from the tig torch hose. So I pointed a fan at the hose and dropped back to about 10% duty cycle and took more breaks. I plan on upgrading the tig torch. Another minor complaint which I read before purchase is the argon connection is a 5/16 hose barb on the back of the machine. Luckily I keep a pile of fittings and stuff and was able to make something work. Third little complaint is the machine needs some pre-flow for argon. The post flow function works great though. Overall I like the machine so far and do not regret my purchase at all.

Every fast delivery and good quality

Solda de manera excelente, lo lleve con un maestro de la materia para que lo checara y me enseñará ya que hasta entonces solo era soldador de mig, le fascinó el equipo y su precio, no he probado el tig y la única pega son sus accesorios que son de mala calidad pero es es entendible y increíble que incluso incluya tantos accesorios como la antorcha tig.

J’ai essayé la soudeuse et c’est vraiment bien. J’ai soudé à la rode sur le 120 volt sur du métal mince avec de la 6013 3/32 et ça fonctionne très bien. Comme soudeuse de dépannage c’est parfait.

es totalmente lo que esperaba

Very good machine for this price

Máquina de soldar de muy buena calidad
