Spot and projection welders – Items 67xx – 90-315 kVA

67xx

This line of welders may be set up according to a wide range of mechanical and pneumatic configurations thus responding to all customer needs while maintaining a high mechanical stiffness that makes these machines the most suitable ones for jobs requiring an extremely high welding quality.

It is possible to configure these machines according to 4 different mechanical frames which differ for an increasing structural rigidity: they can be realized for spot, spot-projection or projection execution. The choice of the arms gap may vary from a minimum of 300 mm, in case of projection execution, up to a maximum of 1500 mm, in case of spot execution.

The required cylinder may be chosen among a range covering from the smallest one developing a 736daN force at 6bar up to the largest achieving a force 5509daN at 6bar.

As for the most suitable transformer for the required application, the available sizes are 90-160-200-240-315 kVA.

The TE700 control unit allows 6 working modes thus enabling to select the best welding procedure for the type of material to be welded. A high precision and constancy of the working pressure may be ensured by implementing a proportional valve in the pneumatic circuit. This proportional valve is directly programmable by the control unit and allows matching each program to its own pressure value.
