Features and functions:
1. Adopt single-tube IGBT high frequency inverter technology, the frequency can reach 25KHz, dynamic response is very quick;
2. Reasonable structure, simple arrangement, easy to check and repair;
3. Adopt PWM control mode, quality is reliable and function is stable;
4. Adopt unique single-tube driving and protection technology, improve the reliability and life of single-tube IGBT;
5. Adopt perfect protection circuit and malfunction show;
6. Three defenses(anti-dust, antisepsis, damp proof,) of internal structure increased the machine reliablity under harsh environment;
7. Small size, light weight, high efficiency and load duty cycle, less noisy;
8. Digital show of welding current and voltage, convenient and intuitive for operation;
9. The core of the main transformer use micro-nanomaterials.
10. High load duty cycle which is more than 60% under 40°C environment temperature and low current.
11. Strong ability to resist power supply fluctuation (320-450v)to guarantee the reliability;
12. With remote-control for welding current;
13. With thrust within adjustable 0-100A;
14. With VRD design;
15. Heating to start arc, the current for heating starting arc is adjustable within 0-135A when the preset current is below 200A;
16. Applicable for welding acid and alkaline welding rods.


Scope of application:
Applicable in the fields same as MOSFET and IGBT Module inverter welding machine, is superior in output power.
