TECNA 2102N spot bench welder — 20 kVA, air-operated, single-phase AC. Maximum welding current of 15,200 amps, maximum electrode force of 420 lbs, and maximum electrode throat depth of 11.02 in. Standard TE550 microprocessor control.
The TECNA 2102N pairs a 20 kVA single-phase AC transformer with air-operated actuation in a spot bench welder configuration. The 2102N provides a maximum welding current of 15,200 amps, a maximum electrode force of 420 lbs, and a maximum electrode throat depth of 11.02 in. The thermal current rating at 100% duty cycle is 3,500 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 16-25 kVA AC bench range, the 2102N pairs a 20 kVA rating with the same 11.02-in. electrode throat as the 2101D, providing additional welding power at equivalent reach.
