Features

  • Start TIG Welding Without Overcomplicating It: the S7 200A welder is made for people who want a simple way to get into DC TIG and Stick welding. HF non-touch start helps you strike a cleaner TIG arc without scratching the tungsten across the metal, making it easier to practice on stainless steel, mild steel and carbon steel
  • Use 110V for Light Work, 220V When You Need More Power: plug into 110V for practice, thin steel and lighter repair jobs. When the job needs more output, 220V gives the machine better power for thicker steel and longer welding sessions. This helps new users choose the right setup instead of expecting full power from a regular household outlet
  • Simple Controls, Easy to Carry, Ready for Small Projects: the compact inverter design makes this welder easy to move around the garage, store on a shelf or bring to a repair job. The LED display and basic current control keep setup straightforward, while hot start, arc force and anti-stick help make Stick welding smoother
  • Important TIG Notes Before You Buy: TIG welding needs argon gas, tungsten electrodes and TIG consumables. Stick welding does not need gas. This is a DC TIG welder for stainless steel, mild steel and carbon steel, and it is not designed for aluminum TIG welding. This information helps you choose the right machine for your specific welding needs
  • Practical Welder for Garage and DIY Jobs: this welder works well for home garage repairs, small shop projects, farm maintenance, brackets, frames, tools and everyday steel repairs. It is not trying to be a large industrial machine - it is built for users who want a compact welder that is easy to set up and useful for real weekend projects
  • Advanced Pulse TIG Function: the built-in Pulse TIG feature allows for better heat control during welding, reducing warping on thin materials and providing cleaner welds on stainless steel and mild steel projects with improved penetration control
  • Complete Dual Process Capability: this machine combines both TIG and Stick welding processes in one unit, allowing you to switch between methods based on your project requirements without needing separate equipment for different welding tasks

  • This machine is actually free
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. ... show more

  • Great Welder for the money.
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. ... show more

  • Great welder for the price.
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.

  • Great for beginners and learning to lay beads!!
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. ... show more

  • Better deal than a HF tig
Very nice welder for the price. I'm not very good at welding but if you dial in your settings right it can lay some nice beads. You can weld thin metal on a 120v 15a circuit but anything more you'll want a 20a or ideally a 240, but that is not at all the machine's fault. It would be nice if it included a better instruction manual. ... show more

  • Waiting to cast judgement!
Unit arrived ahead of schedule so I was excited while unpacking! Once unpacked I found a very low budget welding unit. The welder came with no instructions but finally figured out the starting process. Only tried the MIG weld and it was average. Still waiting on my gas bottle to try the TIG welder so the jury is still out and will update.But as of now I'm not overly impressed ... show more
