TECNA 8004D press-type spot welder — 60 kVA, air-operated, single-phase AC. Maximum welding current on steel of 12,800 amps with 674 lbs of electrode force at 6 bar. Electrode throat depth of 31.5 in.
The TECNA 8004D pairs a 60 kVA single-phase AC transformer with air-operated actuation in a press-type spot welder configuration. The 8004D provides a maximum welding current of 12,800 amps on steel with maximum electrode force of 674 lbs at 6 bar. The thermal current rating at 100% duty cycle is 5,900 amps. A water-cooled transformer, electrode holders, and electrodes support extended duty cycles, with epoxy resin-coated windings for long service life. The 8004D offers an electrode throat depth of 31.5 in.
