The welder adopts unipue assist direst current resistance to improve frequencyof short circuit in low current area with soft arc light, While in high current area, it contrasts with less spark and well function.

Taking quick and accurate output technology of controlling. The welder rejusts conveniently and keep output current stable whenever the fluctuation of voltage and condition.

The controling of time procedure and all kinds of arc dealing function adopts thick film circuit, Not only reduce comp onents on circuit board, but also improve stability and function.

Perfect filter current and heat to protect circrit, which makes the welder safe.

Well control function and strong load adaptability, thea dvanced technology improves the welding functionb, reduces spark.

Adopting diredt current resistance with the tap in center can change the characteristic conveniently.

It is applicable for welding theplate which thickness at least 0.9mm.

Welding power souce includes all kinds of external connecting control signa, It is fit for automatic or robot welding.
