advantages,

1. Small in size and light in weight, medium frequency transformer is tenths of aditional arc welding step-down transformer. The weight of medium frequency transformer is just 1/5-1/10 and size is about 1/3 of the traditional one.
2. It’s very efficient and energy-saving. Due to the small volume, copper loss and iron loss decrease with consumablesthus leading to reduce reactive power loss. The power efficiency is up to 80%-85% and power factor is up to 0.93, which can save more than 1/3 of electricity than the traditional one.
3. Welding current and voltage is continuously adjustable to satisfy various demand for welding process.
4. Stable welding process and good welding forming.
5. Automatic compensation for power grid volatillty, the ability to resist power grid volatillty is strong.
