Features & Advantages
Slow feeding speed with high open circuit voltage for better arc striking.
Unique feedback circuit for both voltage and current confirms stable welding process,less spatter
good
weld bead and good adaptability for continues change in arc length.
Excellent F.T.T - Globule control circuit makes positive striking of arc.
crater current and voltage function for elimination of crater at the End of the weld.
PWM inverter technique with 20 khz operating frequency make the system much responsive.
It can be widely used in Gas-shielded welding, carbon arc air gouging and manual welding.
Usage
It is suitable for welding mild steel, stainless steel, aluminum and their alloy.
The machine can be used for all position welding with solid and flux cored wire.It can be used with Ф0.8 ,
Ф1.0 , Ф1.2 , Ф1.6 depends on model.
It can be used for manual metal arc welding with acid and basic types of electrodes.
