The GZ GUOZHI 50A is a dual-voltage plasma cutter that runs on 110V or 220V and adjusts current from 20A to 50A. It handles voltage swings from 90V to 260V, so it tolerates shaky shop power. It cuts up to 1/2 inch at maximum and about 2/5 inch cleanly, with pre-flow and post-gas to protect the torch and 2T/4T modes for short or long cuts. It suits hobbyists and light fabrication shops that want one machine for both household and shop outlets. Against single-voltage budget cutters it is more flexible, but it is not a high-duty-cycle industrial unit: the duty cycle is 60% at 40A and 100% at 31A, so heavy plate work belongs to bigger machines.

Rated 4.4 out of 5 across 236 ratings, buyers generally find it cuts well for the money and like the dual-voltage flexibility. Complaints tend to center on duty cycle limits and consumable life rather than the machine itself.
The GZ GUOZHI 50 Amp Plasma Cutter is an air plasma cutter with a current adjustment range of 20A-50A. It has a wide-voltage design (90V-260V) that handles voltage fluctuations and converts automatically between 110V and 220V.
It cuts up to 1/2 inch thick. The ideal clean cutting thickness is 2/5 inch, which gives smooth cuts without extra polishing. It cuts alloy steel, stainless steel, mild steel, copper, aluminum and other metals.
The machine has 2T and 4T trigger modes, a test function and post-gas. A digital display shows its settings, and a fan cools it.
