Product Introduction

Full Grid Compatibility++ One-Knob

Full grid compatibility, arbitrary wiring (single-phase 220/380V, three-phase 380V).

Ultra-wide grid voltage adaptation range (140V-510V).

One-knob adjustment, automatically matches welding voltage based on required welding current.

Specifically optimized arc starting function and post-weld ball removal circuit, ensuring high arc starting success rate.

Intelligent gas saving, gas flow system self-control, saves 10~20% gas cost.

Intelligent fan, energy-saving and noise-reducing, reduces dust entry, extends fan life.
