Robot Spot Welding GunsFor More than 40 years, TECNA has marked an outstanding trail of passion, technology & Innovation. Boasting a deep experience oriented to the future, TECNA is now introducing a different & more efficient way to perform the resistance spot welding.
TECNA recalls it's past as well as its many worldwide successful welding units which have stood & still stand for the innovating genius conveying in the clever intuitions &dedication of professional.
Its equipment is always enriched with revolutionary ideas & its ingenious solutions, pushed to the edge of technology & performance, are the outcome of years of constant research & innovation.
Third generation Servo Robot Guns were launched in European market in 2012 & are now ready to hit the Indian market.
A completely revamped product design for Servo Motor Guns.
Modern and novel design, minimum parts and ease of maintenance.
Possibility to integrate a built-in force sensor for closed loop force feedback are the highlights of this generation.
Design - TECNA Robot guns are designed as per European standards. The unique design can accommodate motor from any robot manufacturer. The compactness, user friendliness and maintainability of Tecna manual guns is earned forward to Robot guns design too. Every part or subassembly of the gun is subjected to life cycle test before accommodating into the product. Modular design enables standard parts for all guns.
Product Range - As per TECNA's philosophy of optimisation ,AC robot guns are available in 32 KVA, 36 KVA, 54 KVA, 60 KVA, 75 KVA. MFDC guns are available in 56 KVA and 90 KVA.
Increase in productivity - The electrode opening can be precisely controlled and travel distance between the spots can be reduced. This results in reduced spotting and traveling time. The electrode opening position can be defined for each spot reducing the opening and closing time of electrodes resulting in reduced spotting time
Precise control on Welding Force - 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.
Inbuilt Force Transducer - To receive real time feedback of Force while welding is also available as option. This is achieved by integrating a Force Transducer built inside the gun mechanism.
Precise control on Heat Generated ( Energy Consumed) while welding - 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.
Soft Closing - 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.
Correct welding position - This servo system can identify Tip wear, Deflection in arms and tip position. This helps for correct welding position of the gun.
Environment Friendly - Operational noise of welding gun is reduced by soft closing also they don't produce air exhaust noise.
Conversation with robot - 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.
After Sales - USP of Tecna in INDIA is after sales and service support. This continues with regional offices with adequate spares.
