16-38KVA SPOT WELDING GUNS With TE470 Control

Experts on Tecna Spot Welders with 30+ years of experience introduce the TECNA X Type 3 series range with standard 190mm electrodes and TE470 in-built controls. These handheld air-operated, water-cooled spot welding guns are perfect for production work and come with optional arm lengths.

Includes:  Upper Arm Straight 4850-Length 190mm.  Please call if other lengths are required.

They are designed to be suspended from gantries or a boom for maximum flexibility and manoeuvrability when supported by a balancer. The gyro enables effortless tilting of the gun to reach any angle. With a 16kVA spot welding output at 50% duty cycle and a maximum output power of 37kVA, these spot guns have exceptional welding capacity (with the shortest arms). Additionally, they are equipped with water-cooled arm mounts, electrode holders, transformers, and SCR contactors for optimal performance.

Tecna TE470 Control Unit


The TE470 is a welding control unit specifically designed for suspended resistance welding guns. It expertly controls the welder parts, especially the thyristors that regulate the welding current. This control unit has unique features for suspended welding guns, including double stroke control and safety device management on the handle.

While the handle is not a standard component, it can be customized for different working performances. With a capacity to store up to 63 welding programs and the ability to directly recall 2 programs using an external selector, the TE470 provides versatility and efficiency. Each program has 19 adjustable parameters that describe the working cycle, including options for pre-weld current, post-weld current, slope, and pulses. The TECNA TE470 also operates in constant current mode, displaying and regulating the current according to the set limit.
