TECNA 2103D Spot Bench Welder — 25 kVA Air-Operated Single-Phase AC

TECNA 2103D spot bench welder — 25 kVA, air-operated, single-phase AC. Maximum welding current of 17,600 amps, maximum electrode force of 420 lbs, and maximum electrode throat depth of 11.02 in. Standard TE550 microprocessor control.

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.

Features

  • Standard TE550 microprocessor weld control.
  • Maximum welding current of 17,600 amps with maximum electrode force of 420 lbs.
  • Spot bench welder configuration with water-cooled transformer, electrode holders, and electrodes.
  • Two-stage electric foot control for clamping and welding; two-hand safety control available on request.
  • Built-in compressed air filter unit; lubrication-free pneumatic components eliminate oil mist.
  • Flow-switch halts the machine if cooling water flow is interrupted.

Installation Requirements

  • Water cooling: 3 L/min flow at 2.5 bar minimum pressure.
  • Net weight: 190 lbs. Sound level 71 dB(A). Insulation class F.
