Description
The TECNA 2103D pairs a 25 kVA single-phase AC transformer with air-operated actuation in a spot bench welder configuration. The 2103D provides a maximum welding current of 17,600 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 3,800 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 2103D is the 25 kVA flagship spot model; it shares the 11.02-in. electrode throat depth of the lower-power 2101D and 2102N while delivering the highest welding current in the range at 17,600 amps.
