◆ small size, light weight: IF transformer is only the traditional arc welding power supply step-down transformer

   A few one-tenth; machine weight is only traditional arc welding power 1 / 5-1 / 10; whole

   Machine volume is only about 1/3 of the traditional arc welding power;

◆ Efficient, energy-saving: Arc Welding inverter due to small size, copper consumption and consumption of iron with the consumption of timber

   Reduce the material and greatly reduce reactive power loss, the power efficiency of up to 85%, power

   Rate factor up to 0.93, saving more than 1/3 of traditional arc welding power source;

◆ digital display, can preset current and voltage, backing welding forming a good back;

◆ welding process is very stable, droplet smooth transition, welding spatter, beautiful shape;

   Using constant-speed wire feeding circuit, and the traditional constant-voltage wire feeding circuit has a higher wire feed

   Stability, can be achieved in the whole current range of high stability wire.
