140A MIG Welder, 3 in 1 Welder FLUX MIG/ARC/Lift TIG Multi-Process Mig Welder, 110V Welding Machine, Welder Machine 110v Flux Core Welder with Welding Gun

I am used to reading one-star reviews before buying something, which made me a little worried about the quality of the product, but I liked this product so I still chose to buy it, and tested it as soon as I received it, and Found the quality to be unexpectedly good！The 200P welder performs very well, and you can adjust the power and current by yourself. So far, no material has been burned through during welding. On the contrary, the welding process is very smooth and the weld is flat. Regarding the fact that the tig interface is not universal as mentioned in the comments, I think that has absolutely no impact, I just need to order a TIG gun from the GUIZHI store, it can be installed perfectly, and the price is low. Overall, this is a very practical machine, powerful and easy to carry, and I am very satisfied！

I was very skeptical of a $69 welder. I couldn't buy a grounding cable for my welder for that price. This is a great value. It works. You can weld light stuff just fine. Its very very portable. Its very light weight. I have added this to my mobile mechanic shop to replace my heavy big welder which I rarely use. It saves me space, time and money. And again, it works. I welded many exhausts, many broken bolts and other things. This is the smallest and most portable setup anyone has ever seen. And if it breaks, a new one is cheap enough to where I don't sweat it. Im not sponsored or paid in any way. This welder is the best setup if you need portability and function. I run this on my generator just fine with .030 flux core. Ran about 1 pound so far with no issues.

This welding machine is a game-changer for anyone into DIY projects or repairs. It offers a wide range of functions like MIG, MAG, gasless flux core, TIG, stick, and spot welding, making it a one-stop solution for all your welding needs. The dual voltage feature (110V/220V) is super convenient, allowing you to work in different environments without any hassle. The aluminum MIG capabilities are a definite plus, especially if you frequently work with aluminum materials. The GZ GUOZHI 200A MIG Welder is a compact and powerful tool that packs a punch in terms of performance. However, some users might find it a bit overwhelming at first due to the numerous functions it offers. Nonetheless, once you get the hang of it, this machine will become your go-to for all welding tasks.

Very good welder the mig trigger is a little sticky but not to hard to find the sweet spot

Super surprised and impressed by this machine. I wasn't expecting quality out of a $70 110v machine. Bought to replace a little 110 Lincoln for home use. Haven't tried the stick or tig functions yet but for fluxcore mig this is an amazing welder for the price! I was expecting it to run cold and put down the usual 110 flux boogers but this machine welds nicely and I've ran it for about an hour pretty much straight welding up an exhaust system and it never got hot or shut down. Build quality is good too, nice heavy cord(twice as thick as Lincolns) and heavier gauge steel for the case. Overall super impressed by it and would definitely recommend it to anyone that does small welding projects on a regular basis.

The Guozhi 140 welder arrived today. Upon opening the box and checking the welder over I noticed some damage. The ground clamp is twisted and bent, the handle on the welder has a dent as well. The welding electrode holder seems well built and of good quality, just looks scuffed up. Seems like I received a used item that was returned. Haven't used the welder yet to make sure it works as I am waiting on a new welding helmet as my old halmet quite working. Will be able to test it out by Tuesday afternoon. I bought this welder based on you tube reviews. So far I am not impressed. Will be updating my review by Tuesday. Update on the item. I used the welder today and functions perfectly would definitely buy again. I do recommend this welder to anyone looking for a economical welder with out paying big money. Guozhi made a great welder that works just as good as high end brands.

I should clarify this is only about the shipping speed I do not have the item yet! So I ordered this product on Sunday 3/8/26 & everything online says delivery by friday (I have a project im doing & NEED this item by today) I get emails on when my items ship & this item did not ship until yesterday around 2pm! How can they say it'll be here friday & not ship it until the day before?! Shame on you for false advertisement! The crazier thing is i ordered from the same seller the flux wire & tips etc at the same time & those arrived 2 days ago!🤬 Im not going to lie I am severely disappointed with the way this seller handled shipping this item out! What happened to 2 day shipping with prime?! If you need this item quickly DO NOT ORDER THIS ONE! UPDATE: So my initial review was awful & it did not reflect on the product at all. Once the item arrived it came as advertised. It actually works better than expected for a $70 welding unit. It cant burn 7018 ⅜" rods but it does lay a nice .35" mig weld. Ill attach pics of the mig welds. If you want a good DIY at home welder this is your unit. Make sure you get anti splatter paste & I highly recommend getting .35 wire & tips (its a better wire in my opinion) the machine comes with .30 & .35 tips but you Def need to order more tips these dont feel like they'll last very long. Overall im very satisfied with the product. If it weren't for the shipping issues id give er 5 stars.

I am new to welding and purchased this unit to try welding as a hobby. I was able to load the flux core wire easily although the wire unwound quickly...but it still feeds. The ground connection was a little confusing. The manual says DCEN for flux core. One would think that this means connecting the ground cable to the negative plug. Not so, it is connected to the plug labeled +. Next, inside the lid there is a nice table with recommended initial settings. For flux core 0.03" and 1/16 inch metal, it lists the recommended voltage at 6 and the wire feed speed at 3-4. However, the voltage dial goes from -5 to +5 volts. The wire feed dial goes from 7.5 to 24.6 ft/min. The manual also lists the voltage range 16-20.4 volts. So the recommended voltage and wire speed are below the range stated in the manual. Note: manual pdf shows the proper ground connections but the actual manual in the box does not have that figure. There is a digital display but I am not sure what it is displaying. When set to 0.03" flux core, the digital display goes from 40 to 140 when the wire speed dial is turned. Turning the voltage dial does not affect the digital display. Note: I understand this now..Amps are displayed In the Amazon description it shows 24 hr customer service, but no phone number or email are provided in the manual so who knows how to contact them. The manual is not very helpful. I wish that it explained what the knobs do. For example, does the wire speed automatically set the voltage? Then does the voltage knob increase or decrease voltage from the automatic settings? These questions should be explained in the manual or in the product videos. Note: I did contact the seller. They did respond promptly but their answers were not that helpful. There is a helpful table with recommended settings...however, it is so small that it is really hard to read (and who knows how to set the machine to the recommended settings). Note: the table stuck onto welder is apparently not for this model welder. This thing really needs a table of initial settings as a function of steel thickness. This would really help beginners like me. But, the machine looks cool and it works (at least for flux core)
