Shanghai donsun welding group ZX7 Series IGBT inverter DC arc welding machine
(engineering)
ZX7-400HC /ZX7-500HC
Function ：(Hand welding.)
Application Scope ：welding carbon steel, stainless steel, foundry iron, etc.
Advantage
The machine adopts advanced module IGBT HF inverter technology.
Welding and arc force current can be adjusted respectively, suitable for welding all kinds of acid and basic welding rods.
Welding current is stepless so the machine can be applied in varieties of welding rods in different diameters. The machine can serve as carbon arc
gouging machine when current is over 500A.
The machine can protect itself from the damage of overvoltage, undervoltage, overflow and overload.
Easy arc-striking, stable arc, less splash, beautiful weld forming.
