Easy to use, great for beginners. *by on Reviewed in the United States 30 November 2025* For the $99 cost, this welder is incredibly effective. I've used it for a few months and put it through its paces on Gas MIG and to a lesser extent Flux Core MIG. I am an automotive hobbyist. I do occasional welding for fabrication and repair. I'm not a beginner at welding, but certainly not a professional.I did not use the stick or TIG functions, so I can't comment on them.Pros:- The synergic function works very well for me. Because of this, I can weld better with this unit than my 1997 Lincoln 175A MIG. The wire feed runs smoother, and the weld is smoother. This unit is much easier to adjust for the material and conditions.- I plugged it into a 20Amp 120V outlet and measured 135Amps maximum output. That's not 200A, but you can do anything automotive with this amperage. If you're welding 5/32" or thicker, this is not the welder for you.- It is generator-friendly because it is an IGBT. I normally run it from a 3200 watt generator at 220V. I measured 125A using a clamp on meter running 0.35 flux core MIG wire. This makes a very effective portable welding setup.- I can dial the amperage down and it does a great job with automotive sheet metal and exhaust pipe. I used 0.30 solid MIG. It is very controllable and allows me to build material and not burn through.- Lightweight and small thanks to the efficient IGBT power supply rather than heavy transformers.- The MIG wire feed works great, better than my Lincoln (sorry Lincoln), which suffers from a poorly designed spool holder.Cons:- I doubt if the 200A rating is real. However, I measured 135A on 120V using 0.35 flux MIG, and you can do a lot with this. To be fair, I did not catch the peaks using an oscilloscope, so maybe it can do 200A under the right conditions... I also did not measure maximum output at 220V or using stick. If you need 200A and you're welding 5/32" or thicker steel, you need a bigger welder. I don't think this one will get the penetration you need.- The leads are short. However, the unit is so light and small that you can usually move it closer to your work. You can also use a heavy duty 220V extension cord.- There is an exposed portion of the control circuit board in the MIG wire cabinet. It is okay as is, but I'd hate to see the MIG wire bird-nest and hit this board during operation. I'll eventually cut some milk jug plastic and use a few zip ties to protect it. ### ⭐ Belle machine!!! *by on Reviewed in Canada 29 June 2026* Ça avait l’air bien et je n’ai pas pu l’essayer, la roue de torsion ne tournait pas , ### ⭐⭐⭐⭐⭐ Calidad precio *by on Reviewed in Mexico 7 August 2024* Si cumple con las prestaciones que promete, es perfecto para el que va iniciando y si trabaja durante un buen tiempo, lo recomiendo ampliamente, hasta el día de hoy no he tenido ninguna falla, es de buena calidad. ## Frequently Bought Together - S7 Gas and Gasless 200A 110V/220V Multiprocess MIG Welder - 4-in-1 Welding Machine for Flux Cored, MIG, Lift TIG, and Stick ARC Welding Machine - YESWELDER True Color Solar Powered Auto Darkening Welding Helmet, Wide Shade 3.5/9-13 for TIG MIG ARC Grind Welding Hood Helmet - YESWELDER Gasless Flux Core Mig Wire, Mild Steel E71TGS .035-Diameter, 2-Pound Strong ABS Plastic Spool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/664955738-s7-gas-and-gasless-200a-110v-220v-multiprocess-mig-welder](https://www.desertcart.tn/products/664955738-s7-gas-and-gasless-200a-110v-220v-multiprocess-mig-welder) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-09*
