Thyristor DC MMA Welder

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.

1. This arc welding machine can be used for the manual arc welding of all kinds of electrodes.
2. SCR control technology is adopted, achieving stepless current adjustment. Also, the current is stable and the noise produced during operation is low.
3. The thyristor DC MMA welder is equipped with adjustable arc igniting current and thrust current devices for easy arc ignition. It also supports automatic compensation for mains voltage fluctuations.
4. The welding current can be adjusted from a great distance, facilitating operation.
5. The weld pool is deep, ensuring small splash and beautiful weld, which is conducive to all-position welding.
6. Original imported main circuit power rectifier is adopted. It works stably and reliably.
