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.
