Microprocessor control technology 

Main transformer uses super micro-crystal magetic material.Use IGBT technology,greatly improves the reliability of the machine. 

Small size ,stable and durable quality and energy-saving. 

Good arc-starting and arc force ,stable arc and little spatter. 

High welding quality,deep penetraiton. 

Easy to start arc,little spatter,and good formation. 

Stable welding current in spite of input voltage fluctuation 

Auto protection of over-voltage and over-current. 

Acid and basic electrodes are usable . 

High no load voltage,strong arc force. 

Suitable for welding all kinds of basic welding rod. 

Widely used in indoor decoration,and high working places jobs. 

With arc force and hot arc starting function,also with VRD function. 

Advanced arc force and arc-starting function.
