    • I'm absolutely blown away by the GZ GUOZHI 145A MIG Welder!
The media could not be loaded. This 3-in-1 beast handles FLUX MIG, Lift TIG, and ARC welding like a pro – perfect for my weekend car restoration projects and heavy-duty metal fabrication. The 110V power input is a lifesaver for home workshops; no need for special circuits or worrying about tripped breakers. The large LCD screen makes adjusting voltage and current a breeze, letting me monitor settings without squinting or guessing – a huge upgrade from my old welder. What really impressed me is how smoothly it switches between processes. I welded thin sheet metal with flux core wire on MIG mode one day, then did precise aluminum repairs using Lift TIG the next – all without any complicated setup. The lightweight portable design means I can easily carry it around my garage or toss it in the truck for on-site jobs. IGBT inverter design, Even after hours of continuous use, it stays cool and consistent – no more annoying thermal shutdowns mid-project! The included accessories (like the MIG torch and grounding clamp) feel durable, not those flimsy add-ons you usually get. For under $200, this machine outperforms models Five times the price at my local hardware store. If you want professional-grade versatility without commercial-grade headaches, this welder’s a game-changer! ... show more

    • A solid welding machine with great versatility.

I picked up this welder for my husband because we needed a compact, multi-process machine for small projects and repairs, and this thing delivers big time. First off, the 3-in-1, FLUX MIG, Lift TIG, and ARC, is nice. We mainly use it for flux-core welding, and synergic control makes setup super easy. It automatically adjusts voltage and wire feed speed based on amperage, so beginners can start welding fast without a steep learning curve. There’s also a manual mode for fine-tuning settings if you prefer more control. The LCD screen is clear and easy to read, which is a nice upgrade from older models. The 90V-140V wide-voltage design is great, letting it handle fluctuating power without issues. We’ve used it in cold weather (around -15°C), and it still welded smoothly. It’s lightweight and compact, so taking it to different job sites is no hassle. Despite the small size, it packs in all the essential safety features—overheating, overcurrent, and overload protection. For the price, we got a solid welding machine with great versatility. ... show more

I have been searching for a powerful yet user-friendly welder for some heavy-duty projects, like welding thick metal rods for gate installation, and this 145A MIG welder is a great find. The LCD display is a great feature, making it easy to monitor settings at a glance. One of the things I really appreciate is the automatic voltage and wire speed adjustment when changing amperage, no guess works anymore. I put it to the test on a steel frame for a workbench, and it performed flawlessly. The arc was stable throughout. Safety-wise, over-voltage, over-heating, and over-current protection are all built-in, and It’s also surprisingly portable, making it easy to move between job sites without breaking my back. ... show more

As a weekend warrior, this 3-in-1 welder blew me away! The Lift TIG mode is ideal for delicate jobs, while ARC excels at heavy-duty repairs. The LCD panel is a chef's dream—no guessing amps or speeds, simply flawless welds every time. I love that it works on regular 110V—no tripping breakers or paying an electrician! The flux core feature saved me money on gas, and the compact size suited my small workstation. A little wish? Provide a basic guide for first-timers. But how can I master many approaches without breaking the bank? This machine is a steal—it's fun, versatile, and future-proof! ... show more

    • Great for Beginner
I’m no expert welder, but I needed something easy to use for small projects. This one is just what I needed. Setting it up was simple, and the automatic settings make it much less intimidating. I tried it on some mild steel, and the welds looked pretty clean. I appreciate that it comes with everything to get started, even some wire. It’s also nice that it has safety features built in—no worries about overheating or overloading. ... show more

The operation is simple, the welds are beautiful, and the ARC mode makes it easier for me to handle thicker materials. It can handle both thin plates and thick metals. In addition, the accessories that come with it are very convenient to use. The welding gun feels comfortable and you won't feel tired even if you operate it for a long time. The heat dissipation performance of the machine is also excellent, and it will not overheat even if you work for several hours continuously. ... show more
