Tecna medium frequency, spot and projection, linear action welding machines 6710..6752; nominal power at 50% d.c. 90kVA..315kVA.
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 90kVA-160kVA-200kVA-240kVA-315kVA.
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.
These welders are all provided with inverter technology, which allows a remarkable improvement of the welding quality, an extreme precision of the welding time and current as well as a reduction in costs, including those relevant to the connection.
