TECNA 2946/2947 C-Type Robot Weld Gun — 90 kVA MFDC (Servomotor Actuator)

Description

The TECNA 2946/2947 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 90 kVA medium-frequency (MFDC / inverter) transformer and driven by a servomotor (roller-screw) actuator at 3000 rpm for precise, programmable force control. The gun delivers a maximum welding current of 63,600 amps and a constant 1,124 lbs (500 daN) of electrode force across its short-throat 3.94 in. (100 mm) and 5.91 in. (150 mm) arms. It is offered in two configurations: the US 2947 (EXLAR GTW80 actuator, 480 V / 60 Hz, 73 kg) and the 2946 (4.9 Nm actuator, 400 V / 50 Hz, 83 kg). Water-cooled construction supports continuous robotic duty.

Features

• C-type short-throat robot spot welding gun for automated and robotic applications.
• 90 kVA medium-frequency (MFDC / inverter) transformer; US 480 V / 60 Hz (2947) or 400 V / 50 Hz (2946) configuration.
• Servomotor (roller-screw) actuator at 3000 rpm — EXLAR GTW80 (4.5 Nm) on the 2947, 4.9 Nm on the 2946.
• Maximum welding current of 63,600 amps; constant electrode force of 1,124 lbs (500 daN) on both the 100 mm and 150 mm arms.
• Short-throat arm lengths of 3.94 in. (100 mm) and 5.91 in. (150 mm).
• Water-cooled for continuous robotic duty (4 l/min).

Installation Requirements

• Inverter supply: 635 V / 1000 Hz (US 2947, 480 V/60 Hz) or 500 V / 1000 Hz (2946, 400 V/50 Hz), fed from a TECNA MF inverter.
• Gun weight: 161 lbs (73 kg) for the US 2947 (183 lbs / 83 kg for the 2946); 90 kVA transformer 35.27 lbs (16 kg).
