TECNA PNEUMATIC SUSPENDED SPOT GUNS (3321-3328)

The TECNA pneumatic suspended spot welders from the (3321-3328) series offer a nominal power range from 16 kVA to 38 kVA, ensuring high performance in industrial production.

Designed to maximize productivity, they combine a compact design with a high welding capacity, optimizing space management and ensuring efficient operation. The integrated electronic control unit reduces bulk and installation costs, optimizing electrical efficiency.

The fully enclosed structure, with rubber protection, ensures a safe and comfortable working environment. The gyroscopic suspension system with sealed bearings, combined with a balancer, allows smooth and unrestricted movement in all directions. For greater stability, a rotation lock device is included.

The total cooling system ensures thermal control of the electrodes, electrode holders, arms, transformer, and thyristor, improving machine durability and performance. The adjustable electrode spacing allows optimal adaptation to welding needs, while the adjustable short stroke enables high working speeds.

The instant wide opening allows easy access to welding areas, while the extended working stroke facilitates operations on ribs, reinforcements, and challenging positions.

The spot welders come fully equipped with a magnetothermal switch with a safety circuit breaker for advanced protection. The pneumatic drive system, adjustable in force and speed, combined with a chrome-plated cylinder and rod for heavy-duty service, ensures durability and consistent performance, eliminating the need for oil mist lubrication.

The electronic control system can be selected to best match production requirements. A safety device on the handle prevents accidental activation. Additionally, the quick power cable replacement can be performed without opening the welder, simplifying maintenance.
