TECNA 8216D press-type spot welder — 160 kVA, air-operated, single-phase AC. Maximum welding current on steel of 24,000 amps with 1,654 lbs of electrode force at 6 bar (standard cylinder). Electrode throat depth of 31.5 in.
The TECNA 8216D pairs a 160 kVA single-phase AC transformer with air-operated actuation in a press-type spot welder configuration. The 8216D provides a maximum welding current of 24,000 amps on steel with a standard electrode force of 1,654 lbs at 6 bar; the optional 1242 daN cylinder upgrade (Art. 8235) increases maximum electrode force to 2,792 lbs. The thermal current rating at 100% duty cycle is 9,300 amps. A water-cooled transformer, electrode holders, and electrodes support extended duty cycles, with epoxy resin-coated windings for long service life. The 8216D offers an electrode throat depth of 31.5 in.
