DC Inverter MMA Welding Machine(Module IGBT)

Models:
ZX7-400I/ZX7-400SX/ZX7-500I/ZX7-630I
Features and function: Adopt advanced inverter technology and imported IGBT module, the inverter frequency can reach 20KHz, quick dynamic response, is your reliable choice.

1. High load duty cycle, there is wide allowance in welding capacity, can weld continuously and stably when the cable length is 100 meters long;
2. Voltage-pressure compensation with strong capacity of anti-power fluctuation;
3. Strong thrust regulation function guarantee the stable welding bead formation, which is also convenient to the adjustment of fusion depth and strong adaptability of welding power to the welding procedures without rod sticking. Deep welding fusion, nice welding shape with high quality of welding seam.
4. Can use cellulose covered electrode to do downward welding, also applicable for various kinds of welding rods, especially good in using alkaline welding rods to weld low and medium carbon steel, low alloy steel and stainless steel.
5. ZX7500I and above can use for carbon arc gouging, is multifunctional machine;
6. ZX7-400I especially suitable for electric power construction;
7. Widely used in petroleum pipe, chemistry, automobile, shipbuilding, boilers, electric power construction, nuclear power, aerospace, military project, industrial installation, bridge construction, etc.
