Still need argon bottle and regulator
Very happy with welder seems to work great so far. For a TIG welder under $100 I think it will work great for small projects. The high frequency start works good. Machine is not to loud and it is very portable haven't tried it on120v but works great on 220v. You will need an argon bottle and regulator to get welding. ... show more

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 TIG machine

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

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

Portable welder that fits my small-project plans, with a learning curve
Moving into a rental meant I couldn't set up a proper workshop, so I bought this S7 for occasional metal fixes and small DIY jobs. I took it to a friend's garage last weekend and used the TIG mode to repair a loose tab on a steel shelf. The unit was manageable to carry, and switching between 110V and 220V gives me options depending on where I can work. I liked having stick welding available too, though I haven't used that mode much yet. The part that slowed me down was getting comfortable with the TIG settings; my first bead looked pretty rough. It works for my small projects, but I need practice before trusting myself with anything more visible. ... 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.

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
