Robot Spot Welding Guns - Second Generation

As The welding force is controlled by Current utilized by servo motor, actual force while welding can be controlled precisely. Welding force for each spot can be programmed as per welding requirement of different combination of sheets to be welded

Three important parameters of welding are Current, Time and Resistance. With TECNA constant current secondary feedback Welding Control Current and time are precisely monitored. The contact resistance is dependant on actual force applied while welding. Servo system controls the force accurately resulting in generating required Heat for welding.

Electrode Closing speed is reduced just before they touch the panel. This results in reduced Dents and increase in electrode life as initial impact of electrodes is avoided.

This servo system can identify Tip wear, Deflection in arms and tip position. This helps for correct welding position of the gun

Operational noise of welding gun is reduced by soft closing also they don't produce air exhaust noise.

For the convenience of Integrator and robot manufacturer this system is available with various fieldbus options. Interface modules for fieldbus DeviceNet, Profibus, Ethercat are available as standard, ensuring compatibility of communication protocol with wide range of Robots.

USP of Tecna in INDIA is after sales and service support. This continues with regional offices with adequate spares.
