Pneumatic multi-point welding machine ZW-31-P

The welder ZW-31-P is used for welding the concrete rings meshs. After welding the mesh is rolled with the rolling mill. The multi-point welding machine with pneumatic drive is designed for resistance welding of low carbon steel bars. It can be fitted with an alternating current or direct current welding system. The pneumatic drive is faster, more efficient, quieter than the mechanical counterpart and it’s easier to overdrive. In the device a pressure of electrodes is realized by pneumatic actuators which sequence is controlling by industrial computer with properly loaded net produce program. The pneumatic drive also requires an access to the compressed air system.
