Grid Voltage Adaptive Current Self-Matching
·Full grid compatibility, arbitrary wiring (single-phase 220/380V, three-phase 380V)
·Ultra-wide grid voltage adaptation range (140V-510V)
·Stick welding one-knob adjustment, select electrode diameter, welding parameters self-match
·High no-load voltage, strong output capability:
ZX7-250D with 50m extended welding cable, can stably weld 3.2 electrode
ZX7-315D with 50m extended welding cable, can stably weld 4.0 electrode
