TECNA 3177 MFDC (inverter) scissor-type suspended weld gun — 56 kVA, air-operated, three-phase, single-stage cylinder. Maximum welding current of 25,000 amps.
The TECNA 3177 is a 56 kVA MFDC (inverter) scissor-type (X-type) suspended weld gun with air-operated actuation and a single-stage cylinder, fed from a three-phase supply. Medium-frequency DC delivers stable, low-distortion welds with reduced power draw. It produces a maximum welding current of 25,000 amps, with electrode force of 1,011 lbs (450 daN) @ 8 bar; 764 lbs (340 daN) @ 6 bar on the shortest arm.
