Product Details

Product Features:

1. Small and light: The size of the mid-frequency transformer in this series is reduced to only several % of that in the traditional arc welding machines. Our machines are about 1/5 ~ 1/10 as heavy and 1/3 as big as compared to the traditional ones.

2. High efficiency: Energy efficiency reaches 80~85% and power factor can reach as high as 0.93. Over 1/3 of energy is saved compared to traditional arc welders.

3. Step-less adjustment for welding current and voltage, can fulfil the requirements for different welding tasks.

4. Stable welding with little welding spatter. Nice form of welded seam.

5. Auto-compensation against power fluctuation.

6. Suitable base material: Carbon steel, Low alloy steel, Stainless steel.
