TECNA 2934 X-Type Robot Weld Gun — 90 kVA MFDC (Inverted Roller Screw Servo Actuator)

Description

The TECNA 2934 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 an inverted roller-screw servo actuator — available as an EXLAR GTW80 (12 Nm) or TOLOMATIC CSWX-3 (11 Nm), both 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 944 lbs on the 23.62 in. (600 mm) arm. Water-cooled construction supports continuous robotic duty.

Features

• Light X-type (scissor) robot spot welding gun for automated and robotic applications.
• 90 kVA medium-frequency (MFDC / inverter) transformer; supplied with a US 480 V / 60 Hz unit, with a 400 V / 50 Hz unit also available.
• Inverted roller-screw servo actuator, available as an EXLAR GTW80 (12 Nm) or TOLOMATIC CSWX-3 (11 Nm), both at 3000 rpm.
• Maximum welding current of 63,600 amps; maximum electrode force 1,348 lbs (600 daN) on the shortest arm.
• Configurable arm lengths of 11.81 in. (300 mm), 17.72 in. (450 mm), and 23.62 in. (600 mm); electrode force varies by arm length.
• Water-cooled for continuous robotic duty (4 l/min).

Installation Requirements

• Inverter supply: 635 V / 1000 Hz (US 480 V/60 Hz transformer) or 500 V / 1000 Hz (400 V/50 Hz), fed from a TECNA MF inverter.
• Gun weight: 152.12 lbs (69 kg) with the EXLAR GTW80 actuator; 90 kVA transformer 35.27 lbs (16 kg).
