TECNA 2142D projection bench welder — 125 kVA, air-operated, single-phase AC. Maximum welding current of 46,400 amps, maximum electrode force of 1,654 lbs, and maximum projection plate throat depth of 9.06 in. Standard TE550 microprocessor control.
The TECNA 2142D pairs a 125 kVA single-phase AC transformer with air-operated actuation in a projection bench welder configuration. The 2142D provides a maximum welding current of 46,400 amps, a maximum electrode force of 1,654 lbs, and a maximum projection plate throat depth of 9.06 in. The thermal current rating at 100% duty cycle is 8,400 amps. A water-cooled transformer, electrode holders, and electrodes support extended duty cycles, with epoxy resin-coated windings for long service life. The standard TE550 microprocessor weld control is included. Within the 63-150 kVA AC bench range, the 2142D is the 125 kVA projection variant; its spot-welding counterpart at the same power class is the 2141D, which provides an 11.02-in. electrode throat instead of the 2142D’s 9.06-in. projection plate throat.
