Review: Buena Review: 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. ## Features - WELDING CAPACITY: With a robust 200A output, 110V/220V dual voltage, this welder is in possess of reliable quality and stable performance. This Welder can work with .030"(0.8mm) and .035" (0.9mm) solid core wire, flux core wire. It also performs well with most 6010, 6011, 6013 and 7018 rods in Stick Welding mode. - Supports Gas and Gasless MIG Welding: Compatible with solid wire and shielding gas as well as flux core wire for different welding applications and environments. - Straightforward Controls with No Menu Selection: Simple knob operation reduces complexity and helps beginners focus on welding instead of button selection. - Ideal for Home Workshop and Hands-On Projects: Designed for DIY users, garage welding, repairs, and light fabrication where fast manual adjustment is preferred. - Cost-Effective MIG Welder Focused on Core Functions: By using mechanical controls instead of large display panels, this welder focuses on essential welding performance without added cost. - Knob-Control MIG Welder for Direct Adjustment: Uses traditional rotary knobs for real-time voltage and wire feed control, allowing quick adjustments without navigating menus or screens. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B099J3Y37K | | Batteries Required? | No | | Batteries included? | No | | Colour | Green | | Customer Reviews | 4.4 4.4 out of 5 stars (704) | | Date First Available | 24 July 2023 | | Item Package Quantity | 1 | | Item Weight | 10.1 kg | | Item model number | MIG | | Manufacturer | win-win | | Material | metal | | Package Dimensions | 43.18 x 32.13 x 27.94 cm; 10.07 kg | | Part Number | UPC | | Power Source | ac_dc | | Size | 15 x 10 x 7 inches | | Style | mig welder | | Voltage | 110 Volts | | Wattage | 12 Microwatts | ## Images ![MIG Welder, 200Amp 4 in 1 Gas MIG/Gasless Flux Core MIG/Stick/Lift TIG Multi Process Welding Machine - Image 1](https://m.media-amazon.com/images/I/71dmLBXOckL.jpg) ![MIG Welder, 200Amp 4 in 1 Gas MIG/Gasless Flux Core MIG/Stick/Lift TIG Multi Process Welding Machine - Image 2](https://m.media-amazon.com/images/I/71JaDudUQ3L.jpg) ![MIG Welder, 200Amp 4 in 1 Gas MIG/Gasless Flux Core MIG/Stick/Lift TIG Multi Process Welding Machine - Image 3](https://m.media-amazon.com/images/I/71jkb3x41cL.jpg) ![MIG Welder, 200Amp 4 in 1 Gas MIG/Gasless Flux Core MIG/Stick/Lift TIG Multi Process Welding Machine - Image 4](https://m.media-amazon.com/images/I/81sS0gKx9wL.jpg) ![MIG Welder, 200Amp 4 in 1 Gas MIG/Gasless Flux Core MIG/Stick/Lift TIG Multi Process Welding Machine - Image 5](https://m.media-amazon.com/images/I/61cr6UASLsL.jpg) ## Questions & Answers **Q: Some mig200 reviews have Mig180 pictures. Which is better?** A: 200 is more powerful **Q: What types of wire can the s7 mig-200 welding machine handle?** A: As the machine can do gas or gassless, it uses flux core or solid wire **Q: Will this welder accept 8" 10 lb large wire spool? I measure it and is not possible?** A: 5 lb max **Q: Im not getting an arc on mig any suggestions?** A: Im not getting any arc control either just wire speed.
