TECNA 2915 C-type robot spot welding gun — 56 kVA MFDC with a pneumatic Ø100 mm actuator. Maximum welding current of 39,600 amps and up to 1,144 lbs of electrode force (on the 11.81 in. arm). Configurable with multiple arm lengths (300–700 mm) and an optional 90 kVA MFDC transformer.
The TECNA 2915 is a C-type robot spot welding gun built strong and light for versatile, multi-configuration use on robotic and automated lines. It is powered by a medium-frequency (MFDC / inverter) transformer — 56 kVA standard, with an optional 90 kVA MFDC transformer — and driven by a pneumatic Ø100 mm actuator. The gun delivers a maximum welding current of 39,600 amps and a maximum electrode force of 1,144 lbs at 6 bar on the shortest (11.81 in. / 300 mm) arm; electrode force scales with arm length down to 571 lbs on the 27.56 in. (700 mm) arm. Water-cooled construction supports continuous robotic duty.
