TECNA 2141D spot bench welder — 125 kVA, air-operated, single-phase AC. Maximum welding current of 44,000 amps, maximum electrode force of 1,654 lbs, and maximum electrode throat depth of 11.02 in. Standard TE550 microprocessor control.
The TECNA 2141D pairs a 125 kVA single-phase AC transformer with air-operated actuation in a spot bench welder configuration. The 2141D provides a maximum welding current of 44,000 amps, a maximum electrode force of 1,654 lbs, and a maximum electrode throat depth of 11.02 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 2141D provides 125 kVA in a spot configuration; its projection counterpart at the same power class is the 2142D, which provides a 9.06-in. projection plate throat instead of the 2141D’s 11.02-in. electrode throat.
