MFDC stationary spot welder and projection welder B series

MFDC stationary spot welder and projection welder 25KVA / 55KVA

Application
MFDC stationary spot welder and projection welders are mainly used for hardware welding and copper wire welding of low voltage electronic switch components.

Feature

The resistance welding machine power ranges between 25KVA to 220KVA.
The maximum short circuit current of our welding machine ranges between 15.5KA to 40KA.
At an air pressure of 6bar, the welding pressure of our welder reaches up to a range of 480~15000N.
The effective throat depth is 230mm.
One-stroke cylinder is standard configuration for our welding machine. However, because a double stroke cylinder and servo electric cylinder are both compatible with the welding equipment, customers can choose these cylinder options.
