Technical properties
- Warp resistant machine frame in shell construction with ribbing
- Generously dimensioned add-on switching cabinet to accommodate welding and machine controller
- Absolute separation of machine and control room
- Infinitely adjustable height of lower arm
- Electrode force cylinder with precision guidance and external torsion protection
- Very good efficiency factor due to the close coupling of the secondary circuit
- Infinitely controllable regulation of the electrode force
- Speed of prestroke and return stroke of the cylinder can be controlled separately via throttles
- Four separate cooling water circuits for cooling the current-carrying elements and the power stage
- Welding transformer in cast resin sandwich construction format for water cooling, thermostat switch fully encapsulated on the primary side
- Primary and secondary spools vacuum cast
- Compressed air maintenance unit as standard with compressed air filter, compressed air regulator with manometer
