The L type MFDC spot & projection welder DB-330KVA with roller ram and strong frame, which ensure excellent spot and reliable projection welding process, with the rise of welding current in 3ms and a maximum short-circuit current of 60KA.

Adopting Heron MF inverter controller HRC802/HRC803 and Heron MF transformer, it has exceptional rigidity, a compact design and less space occupation. Further, this product conforms to European CE and North American CUL standards.

The welding workpiece is placed between the upper and lower electrodes, and the welding current and duration are set by the MF inverter resistance welding controller. Additionally, the pressure between the welding rods is adjusted.

MFDC resistance welding machines are primarily used for spot welding and projection welding processes, such as the welding of carbon steel, stainless steel, aluminum, copper and other alloys.

It is a kind of resistance welding process using MFDC inverter power supply. The power input is three-phase power frequency while the output is single-phase medium frequency. The increase in frequency results in a significant reduction in the size of the welding transformer.
