S7 250A TIG Welder with Pulse, Dual Voltage 110V/220V ARC TIG Welding Machine, HF Start, 2T/4T, Portable for Stainless Steel, Aluminum, Metal Fabrication

I'm not a professional or certified welder but I can tell you, this little thing is a game changer for my garage and my DIY projects. It function like it should, never overheat and perform amazing. With a tank of shielding gas, a few welding rods, a tungsten or two and some PPE, you are ready to roll. If you are looking for a small affordable welder for DIY projects and more, this is the one. I recommend 100%

My nephew loved this welder, it was a big surprise. It does everything his old welder didn't do.

Seems to be well built. Will attempt welding some Aluminum.

Bought for a portable welder . Easy to use, it lighter weight faster to deploy then the buzz boxes in the garage. Had to olay with the settings as im stick welding on 120. But functions as advertised . Id say its a quality item for the price.

I’m pretty blown away by this little rig. I got it for a few little exhaust fabrication projects on my rally bikes. I really didn’t even shop around or read reviews I just pulled the trigger on one and it was here in just a few days.First off: the quality of the machine is pretty impressive. I didn’t expect the fit and finish to be as good as it was. I’m also impressed by the fact that it has post flow settings and an automatic gas flow on/offWhat surprised me even more is that this isn’t a strike start welder, it’s not a lift start welder, it’s a high frequency start welder. I thought that feature was reserved for high end machines, yet here it is on a $197 Chinese welder. It’s a super nice feature which allows you to keep your tungsten much cleaner than with strike start.I made two modifications to this machine:1) the 3/32 tungsten holder was more like 1/16, so my fresh 3/32nd tungsten (not included) didn’t fit. I had to grab my 3/32 drill bit and drill it out, not a big deal2) I moved the high frequency start button to a more ergonomic position for my style of welding. That’s not the fault of the machine, just my preference.Overall this is a great machine if you want to learn how to tig weld, or if you have a few projects you need to knock out. I’m very happy so far and will update this review if anything changes.Note: tungsten, argon, regulator, and welding helmet not included. You will need to plan to get an argon tank which is anywhere from $80-180 for a hobbyist plus a fill.Enjoy!Update: it’s been at least 6 months now and the welder is still going strong for my occasional projects. I really cannot think of anything negative to say about this little rig, it has been flawless.

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.

Want to start learning how to TIG weld, get this affordable machine. I’ve had a Lincoln TIG welder for years but wasn’t able to use it very well. Just too complicated on how to use/set up. Purchased this TIG welder and was able to TIG weld immediately! Set power and air pressure for thickness of metal to be welded and you’re ready to go. Simple setup is great but arc initialization is a godsend. Now I can focus on working my basic TIG welding skills and as I get these working well, then I’ll go back to the Lincoln TIG welder to figure our how to use all of its controls.
