Weldpro vs Guozhi Spec Comparison
Amperage Output
The W Weldpro MIG140 delivers a maximum output of 140A. This level of power is sufficient for MIG welding up to 4mm thickness and MMA or Lift TIG up to 6mm. It uses IGBT inverter technology for stable arcs. In contrast, the GZ Guozhi MIG-200LCD-P offers a higher maximum amperage of 200A. This increased power allows for welding thicker materials more efficiently. If your projects involve heavy gauge steel or require deeper penetration on thicker plates, the Guozhi unit provides more raw power. For thin sheet metal or light DIY repairs, the Weldpro’s 140A is adequate. You should choose based on the thickest material you plan to weld regularly.
Welding Processes
Both machines are multi-process welders, but they differ in variety. The W Weldpro is a 5-in-1 unit. It supports Synergic MIG, Thickness MIG, Stick (MMA), Lift TIG, and Spot Welding. It does not list a dedicated pulse mode or spool gun support. The GZ Guozhi is a 10-in-1 machine. It includes Pulse MIG, Double Pulse MIG, Pulse Lift TIG, Gas MIG, MAG, Flux Core MIG, Stick, Lift TIG, Spot Welding, and Spool Gun capability. The Guozhi offers significantly more process options, especially for aluminum welding via pulse modes. If you need to weld aluminum or use a spool gun for soft wires, the Guozhi is the superior choice for versatility.
Material Compatibility
The W Weldpro is designed for steel, stainless steel, cast iron, and mild steel. It supports gasless flux core welding, which is ideal for outdoor work where wind might blow away shielding gas. It handles 0.030 and 0.035 flux core wire. The GZ Guozhi explicitly lists aluminum as a compatible material. It supports 0.035 and 0.045 aluminum wire, making it suitable for non-ferrous metals. It also handles solid stainless steel wire and flux core wire in various diameters. If you plan to work with aluminum alloys, the Weldpro cannot handle this material. The Guozhi is the only option for aluminum welding in this comparison.
Display and Controls
The W Weldpro features an LED display with intuitive control knobs. It allows for precise voltage adjustments of ±3V. You can select between 2T and 4T trigger modes. The setup takes about 10 minutes. The GZ Guozhi uses a large LCD screen with a menu-based design. It allows for presetting current and voltage parameters. It includes a smart memory mode that stores welding parameters, so you do not need to readjust settings for different thicknesses. It also features gas and wire detection functions. The Guozhi offers more advanced digital control and parameter storage, which benefits users who switch between different materials frequently.
Portability and Weight
The W Weldpro is designed for portability. It weighs 7.5 pounds and has compact dimensions of 11.5 x 6.1 x 9.6 inches. It includes a carry handle and is easy to transport for on-site jobs. The specifications for the GZ Guozhi do not list weight or physical dimensions. Weighing 7.5 pounds, the Weldpro is light enough for one-handed carrying. If you need to move the welder frequently between workshops or job sites, the Weldpro’s lightweight design is a practical advantage. The Guozhi’s heavier build, implied by its higher amperage and larger feature set, may be less convenient for frequent transport.
