The ZX5 series thyristor DC MMA welder is characterized by high efficiency, small no-load loss, and remarkable energy-saving effect. Equipped with integrated components, this welding machine boasts stable arc, calm weld pool, small splash, and excellent welding performance. It can also automatically compensate for voltage changes.

Our thyristor DC MMA welder is easy to operate and the current can be remotely adjusted. This welding equipment is suitable for welding low-carbon steel, medium-carbon steel, and low alloy steel components. It can be applied in the oil, pressure vessel, food machinery, metal structure, chemical machinery, car manufacture, shipbuilding, pipeline project, and other fields.
