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%

I have always used a MIG welder, and needed to get into stainless steel TIG welding, so I was referred to this unit. For the price, it works well. I am inexperienced TIG welder, but enjoyed learning on this one. I have already done a lot with it successfully, but still have much experimenting and trial and error to do. I would say it's a good value and product, and am pleased with the purchase.

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.

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.

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.

This review is for the blue S7 HF TIG Welder - so far this little machine works really well for me and I have been using it for a month to weld the frame and fabricate parts for my bobber build. I dropped a star only for the ridiculous ground cable and zip-tied trigger. I included a picture of the first try out of the box (it’s been 15+ years since Lincoln Electric welding school...). This was done with the welder plugged into 240v, 85 amps, 15 CFH Argon, 1/16” Tungsten and #5 cup (I didn’t test it in a 120v outlet). It is very simple, easy to use, HF start, BUT BUT BUT this is NOT a “buy it and weld” purchase...there is quite a bit of stuff I needed to obtain to get to that first weld bead... Here’s a list of what I used, hope it helps the new welders out there.Argon cylinder – I got a 40CF pure argon cylinder which at 10 to 15CFH is around 3 hours of arc time... plenty for my project. $180Argon Regulator – I had one laying around from my Lincoln days.Argon hose – This confused me as there is a barb attachment on the back of the unit. I found that a standard propane hose worked great and was super inexpensive. A 5’ hose with 1/4” male pipe thread x 3/8’ female flare was $16 – I just cut off the flare fitting and put the cut hose on the barb fitting on the welder with a pipe clamp, other side with the 1/4” male to the regulator with the following fittings.Flare Union: 3/8 in FL x 1/4 in MIPBrass Pipe Coupling: 1/4 in FIP3/8”-5/8” hose clamp for the barb fitting (the propane hose is 1/2” OD)Teflon TapeTungsten - 1/16” 1.5-2% Lanthanated. 1/16” is the only size that fit into one of the two unmarked (metric?) collets that came with my welder.1/16” TIG Filler rod – I used mild steel ER70S-6 (match the rod to the tungsten 1/16”->1/16”)Welding Helmet – Definitely get a quality auto darkening helmet as TIG welding is super precise and visibility is key. Forget that old “can’t see a darn thing without the arc” stick helmet, TIG is a different animal.And of course - leather gloves, a grinder to sharpen tungsten, pieces of steel to weld together, a three prong 240v outlet and a ton of patience.Hope This Helps... Good Luck, dream big and get off the flippin couch and build stuff.

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.
