What Is the GZ GUOZHI 145A MIG Welder?
The GZ GUOZHI 145A MIG Welder is a compact 110V welding machine designed mainly for gasless flux-core MIG welding. It also supports Stick welding and Lift TIG, but you need to buy a compatible TIG torch separately if you want to use the TIG function.
The MIG-145LCD is made for buyers who want a portable machine for home repair, auto body patch work, sheet metal projects, small steel structures, and garage use. It uses a large LCD screen and synergic control, which means the machine can adjust voltage and wire feed speed as you change amperage. Manual mode is also available for users who want more control.
This is not a full industrial welder and it is not a gas MIG setup. Its strongest role is light to medium DIY steel work where 110V power, small size, and simple setup matter more than maximum output or advanced welding modes.
Before You Buy: This model is listed as a gasless MIG welder. It does not perform gas MIG welding, and the Lift TIG torch is not included in the box. Buy it for flux-core steel work first, not as a complete TIG or aluminum welding setup.
Who Should Buy It?
Best For
- DIY users who want a 110V flux-core welder for home repair and small steel projects.
- Beginners who want LCD feedback and synergic controls instead of fully manual setup from the start.
- Garage users who need a compact machine that is easier to carry and store than a full-size welder.
Skip If
- You need gas MIG welding with shielding gas.
- You want a TIG-ready kit that includes the TIG torch.
- You need a heavy-duty shop welder for thick structural work or long production runs.
Key Features of the GZ GUOZHI 145A MIG Welder
The main appeal of this welder is its 3-in-1 function. It supports FLUX MIG, Stick/ARC, and Lift TIG, which gives you more flexibility than a basic single-process flux-core unit. For a home user, that can reduce the need to buy separate machines for basic repair work.
The LCD screen and synergic control system also make setup less confusing. Instead of forcing you to adjust every setting from scratch, the machine can change voltage and wire feed speed as you adjust amperage. That helps beginners get started faster, while manual mode gives experienced users room to fine-tune the arc.
The wide-voltage design is another useful detail. The listing describes a 90V to 140V range, which can help in garages, sheds, or job areas where household power is not always steady. You should still use a safe outlet, proper extension cord rating, and the manual’s power guidance.
Welding Capability and Material Use
The GZ GUOZHI MIG-145LCD is built around gasless flux-core MIG welding. That makes it practical for outdoor repairs because flux-core wire does not rely on external shielding gas in the same way a gas MIG setup does. For many home users, that means fewer accessories and less setup time.
The machine supports 2 lb spools of flux-core wire and is listed for .030 inch and .035 inch flux-core wire. It can also use welding rods below 1/8 inch for Stick welding. These details make it better suited for small repairs, brackets, light fabrication, sheet metal, and general steel work than for thick industrial projects.
The listing also states that it can weld low-carbon steel, stainless steel, and steel materials as thin as 0.8 mm. Thin material still takes practice because too much heat can cause burn-through. The precise current control is helpful here, but you should test on scrap metal before welding the final piece.
Controls, Display, and Ease of Use
The large LCD display is one of the most beginner-friendly parts of this machine. It gives you clearer setting feedback than a plain dial-only welder, which helps when you are learning how amperage, voltage, and wire feed affect the bead.
Synergic control is useful for first-time users because it reduces guesswork. You can adjust amperage and let the machine help match other settings. Once you gain experience, manual mode lets you make your own adjustments for bead shape, penetration, and arc feel.
Pro Tip: Start with scrap metal that matches your project thickness. Make a few test beads, check penetration and spatter, then adjust wire feed and amperage before welding the actual part.
Design and Portability
At 15.02 pounds and 13.3 x 5.8 x 9.2 inches, this welder is easy to move around a garage, shed, or small work area. That size makes it a good fit if you do not have a permanent welding bench or need to store the machine between jobs.
The compact body is also useful for outdoor repair work, small property maintenance, and mobile hobby projects. You still need to account for clamps, wire, helmet, gloves, rods, and other gear, but the welder itself should not be hard to carry.
The tradeoff is that small welders are not built for every heavy-duty task. If you often weld thick stock, run long beads, or need continuous professional output, a larger dual-voltage or higher-output machine may be a better match.
Safety Measures and User Protection
The GZ GUOZHI 145A MIG Welder includes protection against overheating, over-current, over-voltage, and overload. These features are useful safeguards, especially for beginners who may not yet understand how heat buildup affects a welding machine.
Built-in protection does not replace safe welding habits. You still need an approved welding helmet, gloves, long sleeves, proper footwear, ventilation, and a clean work area free of flammable material. You should also use clamps correctly and follow the manual before changing wire, rods, or torch accessories.
Because this is a 110V welding machine, many buyers may use it in home garages. Check your outlet, breaker, and extension cord rating before you start. A weak cord or overloaded circuit can cause poor performance and create a safety risk.
Package Contents and Accessories
The package includes the 145A MIG welder, a 500A electrode holder, a 500A earth clamp, a pre-installed MIG gun, welding wire, and two gun accessories. That gives you enough core hardware to begin setting up for basic flux-core MIG and Stick work.
The missing item to notice is the TIG torch. The listing states that the machine supports Lift TIG, but the TIG gun is not included. If TIG matters to you, plan for that extra purchase and confirm compatibility before ordering.
The listing also notes an AK14 MIG gun and a 10-25 mm universal interface TIG gun for the MIG-145LCD. That is helpful for accessory planning, but you should still compare your replacement parts against the current product listing and manual before buying parts.
How It Performs in Real Use
For Home Repairs
For small steel repairs around the home, the GZ GUOZHI 145A MIG Welder is practical because it runs on 110V and uses gasless flux-core wire. It is a good fit for brackets, small frames, mower or trailer touch-ups, and basic garage repairs where portability matters.
For Sheet Metal and Thin Steel
The listing supports steel materials as thin as 0.8 mm, which makes the machine useful for light sheet metal work. Thin metal is easy to overheat, so the current control and test-piece setup matter. Short welds, clean metal, and practice passes can help reduce burn-through.
For Outdoor Repairs
Flux-core welding is useful outdoors because you do not need a shielding gas bottle for the MIG function. Wind can still affect results, but this setup is simpler than carrying a gas cylinder for small repairs. The compact size also helps when you need to move the machine around a yard, driveway, or work area.
For Learning and Skill Building
Beginners should find the LCD screen and synergic controls helpful while learning basic settings. The machine gives you room to practice flux-core MIG first, then try Stick welding and Lift TIG later if you buy the needed accessories. It is best as a learning and repair tool, not as a replacement for a full welding shop setup.
Setup Tips Before First Use
Read the manual before powering the welder on, even if you have used other machines. Confirm the wire size, polarity, clamp placement, and process mode before striking an arc. Small setup errors can cause spatter, poor penetration, wire feeding problems, or weak welds.
Clean the metal before welding. Paint, rust, oil, and dirt can make the arc unstable and weaken the finished bead. Flux-core welding can handle less-than-perfect conditions better than some processes, but clean steel still gives you better results.
Match the wire or rod to the job. The machine is listed for .030 inch and .035 inch flux-core wire and rods below 1/8 inch for Stick welding. Do not assume every wire, rod, or torch accessory will fit without checking the machine specs first.

Is It Worth the Price?
The GZ GUOZHI 145A MIG Welder looks like a strong value for the price if you want a compact 110V machine for small steel projects. Its value comes from the mix of gasless MIG, Stick, and Lift TIG support, plus the LCD screen and synergic controls.
It makes the most sense for buyers who care about portability and simple setup more than advanced welding modes. You get the most value if your main work is flux-core MIG welding on light to medium steel, with occasional Stick use.
It is not the best fit if you need gas MIG, included TIG accessories, aluminum welding, or a welder built for daily professional fabrication. In those cases, a larger machine with more power and more complete accessories may be worth the extra cost.
How It Compares to Alternatives
Compared with a basic flux-core-only welder, the GZ GUOZHI 145A MIG Welder gives you more process flexibility because it supports Stick and Lift TIG. Compared with larger dual-voltage welders, it is easier to carry and simpler to use, but it gives up higher output and heavier-duty capability.
If you want a more powerful setup, compare it with dual-voltage MIG welders in the 160A to 200A range. If you want the simplest entry point for light repairs, this GZ GUOZHI model makes more sense because it keeps the controls, power needs, and storage demands manageable.
