Main Features:

1)Wide adaptability and can be applicable to welding carbon steel, stainless steel, alloy steel and cast iron, etc.

2)The inverted frequency reaches 100kHz, corresponding with a dynamic response. Being easy in arc directing, low noise in welding processing, and with few splashes.

3)Being widely adjustable in output current,smooth in electrical arc and the welding seams is always formed in elegant shapes and of good welding quality.

4)For different methods of welding craftworks, you are enjoying a quick response of arc initiating and arc ending, which guarantee the best welding quality.

5)Its dependable protection against the Imperfect Phase, voltage exceeding norm +10%or voltage below norm -10%, The protective system gives light warning when the over-heat or over-current occurs. System will recover its functions automatically followed by the protection release. 

6)With features of highly abrupt reduction of constant current, high steady-state output current, strong ability to resist the undulation of voltage of electri network.

7)High efficiency, energy saving. small in dimension, light in weight.simple operation, economic, durable and reliable.
