TECNA 2933 X-type light robot spot welding gun — 90 kVA MFDC with a belt-driven servomotor actuator (4.9 Nm, 3000 rpm). Maximum welding current of 63,600 amps and up to 1,348 lbs of electrode force (on the 11.81 in. arm). Available with 300–600 mm arms; supplied with a US 480 V/60 Hz transformer (400 V/50 Hz also available).
The TECNA 2933 is a light X-type robot spot welding gun built for versatile, multi-configuration use on robotic and automated lines. It is powered by a 90 kVA medium-frequency (MFDC / inverter) transformer and driven by a belt-driven TECNA servomotor (4.9 Nm, 3000 rpm) for precise, programmable force control. The gun delivers a maximum welding current of 63,600 amps and a maximum electrode force of 1,348 lbs on the shortest (11.81 in. / 300 mm) arm; electrode force scales with arm length down to 854 lbs on the 23.62 in. (600 mm) arm. Water-cooled construction supports continuous robotic duty.
