TECNA 2125D spot bench welder — 63 kVA, air-operated, single-phase AC. Maximum welding current of 28,000 amps, maximum electrode force of 1,056 lbs, and maximum electrode throat depth of 11.02 in. Standard TE550 microprocessor control.
The TECNA 2125D pairs a 63 kVA single-phase AC transformer with air-operated actuation in a spot bench welder configuration. The 2125D provides a maximum welding current of 28,000 amps, a maximum electrode force of 1,056 lbs, and a maximum electrode throat depth of 11.02 in. The thermal current rating at 100% duty cycle is 6,200 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 32-63 kVA AC bench range, the 2125D is the 63 kVA spot flagship; it shares the 11.02-in. electrode throat of the lower-power 2121D and 2123D while delivering the highest welding current in the range.
