TECNA 3127 scissor-type (X-type) suspended weld gun — 36 kVA, air-operated, single-phase AC with separate weld control. Maximum welding current of 22,000 amps and up to 1,011 lbs of electrode force at the standard arm.
The TECNA 3127 is a 36 kVA single-phase AC scissor-type (X-type) suspended weld gun with air-operated actuation, built for production spot welding. It delivers a maximum welding current of 22,000 amps, with electrode force from 1,011 lbs (450 daN) on the shortest arm down to 292 lbs (130 daN) at full 31.50 in. (800 mm) reach (8 bar). The 3127 is the separate-control version, operated by a standalone TE560 control unit (Art. 1253/1254); its built-in-control twin is the 3126.
