Developed for heavy-duty industrial fabrication, this 380V three-phase welder applies industrial-grade IGBT DC inverter technology to sustain stable high-power output during long-hour heavy welding. Built-in standard remote adjustment function allows workers to tweak welding current beside large workpieces, avoiding frequent round trips and lifting operation safety.
Max 400A high current output matches thick steel plate welding, with 60% duty cycle at full power and 100% continuous running at 310A without overheating. 65V high no-load voltage creates strong arc thrust to prevent electrode sticking and guarantee deep penetration for structural steel, pipeline and heavy machinery processing. It supports industrial electrodes φ1.6mm–5.0mm to cover all heavy fabrication scenarios.
The thickened shockproof metal frame resists collision and drop in rough construction sites. Complete protection against overload, overheat, over-current and undervoltage greatly lowers failure rate. IP21S dustproof housing withstands workshop oil mist and metal powder. Measuring 58×40×46cm and net weight 19kg, its stable base structure ensures steady placement on factory production lines for long-term batch welding work.
