Feature Specification Importance Input Power Three-Phase 380V or 415V Crucial: Required to sustain 400A output for long periods without tripping. Welding Processes MMA (Stick) / TIG (DC & AC/DC) / MIG (often multi-process) Versatility for different applications (e.g., TIG for aluminum/stainless steel). Duty Cycle 400A @ 60% or higher (e.g., 300A @ 100%) A 60% duty cycle at maximum output means it can weld continuously for 6 minutes out of every 10 at 400A. Weight Generally 25 kg and up (often trolley-mounted) Reflects the size of the internal components and cooling system needed for true high power. Features Full digital control, VRD (Voltage Reduction Device), adjustable Arc Force, dedicated cooling support. Necessary for precision and safety in industrial settings.
