GZ GUOZHI 140A MIG Welder | 3-in-1 Flux MIG / ARC / Lift TIG, 110V, Portable

Overview

The GZ GUOZHI 140A 3 in 1 welder combines flux MIG, arc MMA, and Lift TIG in a compact, ready-to-work package. This single machine is designed to handle a variety of metal projects with smooth arc stability and neat welds, whether you are in a small shop or on a job site.

Three welding modes in one tool

With Flux MIG you get fast, efficient welds on sheet metal and light frames. Switch to MMA for robust arc joints using common rods. When you have an optional TIG lift torch, Lift TIG enables refined joints on thinner materials and stainless steel.

• Flux MIG for quick fabrication and minimal splatter
• MMA arc for sturdy welds on thicker steel
• Lift TIG for cleaner, precision welds on thin metal

Synergic control plus manual flexibility

The MIG unit uses synergic control that automatically adjusts voltage and wire feed as you set amperage. Beginners can rely on automatic changes, while professionals can switch to manual mode to fine tune parameters for tighter control.

• Automatic parameter adjustments simplify setup
• Manual mode offers parameter freedom

Power, compatibility, and performance

Designed for variable power environments, the 90V–140V range helps you manage fluctuating inputs. It can feed up to a 2 pound Flux-Core wire spool and supports Ø0.03 and Ø0.035 flux-core wire. For certain projects, you can weld with 1/8 inch or thinner rods using MMA, and with the optional TIG lift torch you can tackle stainless steel. The unit is built to perform in cold conditions, including operation at minus 15 degrees, making it versatile for outdoor use.

Safety first and portable by design

Overheat, over-current, over-voltage, and overload protections add a layer of safety, helping you work with confidence. The compact size and light weight support easy transport for outdoor repairs or aerial work where space and power are limited.
