Description
The TECNA 2900 is an X-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 Ø125 mm actuator. The gun delivers a maximum welding current of 39,600 amps and a maximum electrode force of 1,124 lbs at 6 bar on the shortest (11.81 in. / 300 mm) arm; electrode force scales with arm length down to 559 lbs on the 27.56 in. (700 mm) arm. Water-cooled construction supports continuous robotic duty.
