The media could not be loaded. I’m really impressed with the GZ GUOZHI 145A MIG Welder. For such a compact and lightweight machine, it delivers solid performance. The LCD screen makes adjusting settings very easy, and switching between Flux MIG, Stick, and Lift TIG is simple and convenient. I’ve used it for small repairs and DIY projects on mild steel and stainless steel, and it works great. The welds are clean, the arc is stable, and it’s very beginner-friendly. The fact that it runs on 110V is a big plus because I can use it anywhere at home without special wiring. Overall, this is a versatile and reliable welder at a very affordable price. Perfect for hobbyists, DIYers, and light repair jobs. Highly recommended!

Bought this GZ Guozhi 3 in 1 Welder Flux MIG/Lift Machine for my husband and he adores it. He is amazed by the performance and excellent-multifunction welder for DIY home projects.

The media could not be loaded. This 145A MIG welder has been a solid performer for the price. I’ve used it for small fabrication and repair jobs around the garage, and it lays down a surprisingly clean bead once you get your settings dialed in. The setup was straightforward and the machine feels well-built for its size. I haven’t tried the TIG function yet, but as a MIG unit it works great for mild steel and light fabrication work. The portability makes it perfect for quick fixes or on-the-go jobs, and the arc is smooth with minimal spatter. Excellent value for any home mechanic or hobbyist welder. Pros: Easy setup and portable design Smooth arc with minimal spatter Great for home and garage projects Feels solid and reliable Cons: Haven’t tested TIG function yet Included accessories are basic

I picked up the GZ GUOZHI 145A MIG Welder mainly for small repairs and DIY projects, and it’s been a great tool to have around. It’s a 3-in-1 machine that does MIG, Lift TIG, and ARC welding, which gives a lot of flexibility depending on what you’re working on. Even though I’m not super experienced with welding, the setup was easy and the LCD screen makes it simple to adjust settings. I’ve used it on a few metal pieces and some exhaust work, and it handled everything smoothly. The welds looked clean and strong, and the machine didn’t bog down or overheat. It came with everything I needed to get started, including the torch and cables. I didn’t know much about TIG welding before, but it looks like the torch included can be used for that too, which is a nice bonus. Overall, I’m really happy with it. It’s compact, easy to use, and works well for the kind of jobs I do at home. Definitely worth checking out if you want a reliable welder without spending a fortune.

This MIG welder is very easy to set up and use, even for beginners. The LCD screen is clear and makes adjusting settings simple. I like that it works as a 3-in-1 machine, giving me the option of MIG, TIG, or ARC welding. For the price, it’s a solid and reliable welder that gets the job done well.

This MIG welder is a fantastic value. I’ve been using it for a few weeks now, and it handles everything from Flux MIG to ARC with ease. The large LCD screen makes it super easy to adjust settings, and the automatic voltage and wire feeding adjustments in MIG mode are great for beginners like me. It’s lightweight and portable, perfect for small jobs and outdoor work. The machine's protective features (overheating and over-current) give me peace of mind while welding. It’s really versatile and works well even in colder conditions. Highly recommend for anyone looking for a solid, budget-friendly welder!

I’ve been using this 3-in-1 welder and I really like it. Setup was quick and simple right out of the box, and it runs smoothly whether I’m using MIG, TIG, or MMA. I’ve done a few small repairs and some light fabrication with it, and it’s handled everything cleanly with solid penetration. What I like most is the compact size. It is very easy to move around, but it still has plenty of power. For the price, it’s a great value, and it saves me from needing multiple machines. I’d definitely recommend it to beginners or hobbyists who want something versatile and hassle-free.

So where do I begin It actually works pretty good The hell when I got I can't get the darkness lighter so I couldn't see if I was going in a straight line But it went through a 1/8 steal. At 70amp 16v There is one thing that if you've never rolled before and I have But it's. Been here since i've used a meg welder There is zero instructions on how to feed this thing and there's no adjustment on the speed control So if you're a beginner good luck trying to feed this thing through without instructions I knew how to do it so it wasn't no Problem This one of the things the handle one of the screws was in the box and it was stripped out so I had to use a quarter inch self tapper to go into the sheet medal on top to hold the handle on. I did it because I wasn't about to send this thing back because of that Here's some pictures don't laugh or make bad comments because yeah they look like crap Cause I couldn't see where I was going. Finally got the hang of it on the last try
