• Description：
  

1. Input power: 380V, 50/60Hz;

2. Inverter arc welder with advanced IGBT transistor technology. Adopts high-performance IGBT inverter core to realize stable current output, energy-saving and efficient operation, as well as strong anti-interference capacity for reliable welding in complex power environments.

3. Compatible with various welding electrodes (E6013, E7018, E6010, etc.). Widely adaptable to common industrial welding electrodes of different specifications, fits well with carbon steel, low alloy steel and other mainstream materials.

4. Multiple core functions & comprehensive protections: Hot Start, Arc Force, Anti-Stick, and Overheat Protection. Hot Start ensures easy arc striking without failure; Arc Force enhances welding penetration for neat welds; Anti-Stick prevents electrode adhesion to improve efficiency; Overheat Protection extends service life, fully guarding safe and stable welding.

5. Boasts fast dynamic response and excellent welding performance, featuring minimal spatter, smooth neat weld beads, high strength and outstanding durability. Rapid dynamic response adapts to different welding speeds instantly, minimal spatter reduces post-welding cleaning work, smooth uniform weld beads ensure beautiful finish, while high strength and excellent durability meet long-term use demands for reliable welding quality.

6. Unique dust-free cabinet design to increase service life of circuit board .  

7. Rugged & robust construction perfectly suited for light and heavy industries as well as for home maintenance, DIY metal crafts, small workshop light welding tasks.

8. The machine comes with a complete set of accessories including:

√ electrode holder ,2.0m

√ earth clamp 2.0m
