IGBT DC inverter dual voltage 220v 380v other stick mma welder arc welders ZX7-315/400GS ( 1-220V/3-380v)

The ZX7 series inverter DC manual arc welding machine produced by our company is a high efficiency and energy saving DC welding power source. The IGBT power switching device is used to invert the 50Hz power frequency to 20KHz high frequency through advanced PWM pulse width modulation technology. Then, step-down rectification is performed, and a high-power DC power source for welding is output. The welders have the following notable features:





1. Uses the most advanced contra variant technology and the IGBT power switch component manufacture, highly effective, energy conservation



2. This welding machine may guarantee the welding current is highly steady in the electrical network voltage undulation and in the electric arc length change situation, the electric arc from adjustment ability, the electric arc is gentle



3. The dynamic response is quick, the welding splashes slightly, the electric arc is steady, the welding performance is outstanding, the welded joint forming is artistic;



4. Has the consummation protection characteristic: Guards against the electric current to attack the slow starting, the overflow superheat protection;



5. The soft switch starts, the volume small, the weight is light;



6. ZX7-315,400,500,630 welder can use 3-phase 415v+/-10% voltage, 50/60 Hz power source;



7. ZX7-315,400,500,630 welding machines are designed and manufactured according to national standard, and the standard is GB15579.1-2004.

Scope of application:



This series of welding machines can weld thin plates and medium-thick plates of carbon steel, stainless steel and other materials; mainly used in stainless steel products, but also for bottom welding of pipelines, petrochemicals, pressure vessels, etc.

1)ZX7-315GS/400GS Suitable for 1 phase 220V,3 phase 380V 2 power voltage intelligent switch,application area widely.

2) Small dimension,light weight,significant energy saving.

3) Simple circuit,high capacity of resisting disturbance.

4) Welding current digital display,accurate current preset before welding(control precision 1A).

5)arc striking current can be adjusted alone,suitable for arc striking for different thickness work-piece.

6)Thrust current can be adjusted according to the  length of welding cable,realize  long  distance welding.

7)Various safety protection function such temperature protection and so on.
