MMA Inverter Welding Machine (ZX7 400)

Functions and Features:

1) Welding Manner:Electrode welding

2) Scope of Application:Shipbuilding,Power Supply,Installation of Miniature Steel Structure, Industrial Manufactury,Maintenance,Installation of Civil Steel Structure.

3) Applicable Materials:Acid Electrodes,Alkalescence Electrode,Stainless Steel Electrodes,Cast Iron Electrodes and can also weld Low Carbon Steel,Medium Carbon Steel,Alloy Steel,etc.

4) Advanced Inverter Technology:Portable,light,portable and cost effective.Voltage compensation function with strong capacity of anti-power fluctuation;High duty cycle keeps continuous welding.Three defenses(anti-dust,damp proof,antisepsis) of internal structure improved the machines' working reliability under harsh environment.    

5) Precise Control System:Adopted full-bridge inverter technology with advanced single-tube IGBT and frequency about 25KHZ,Current-mode Pulse width modulator(PWM) controller of control circuit provides invariable and stable current with precise control and excellent performance.

6) Excellent Welding Performance:The inside self-adaptability function of thermal arc starting greatly improved the success rate of arc starting.Deep weld funsion,nice welding shape with high quality of weldment.    

7) Perfect Protection System:Protection on over-current,over-heat,and under-voltage especially the inside temperature monitored(when the temperature reach to a certain degree,the inside protective circuit will give a early warning and over-heat LED will be on)ensures machines' safety,durability and reliability.
