TECNA 2115F projection bench welder — 56 kVA, air-operated, MFDC / inverter. Maximum welding current of 25,000 amps, maximum electrode force of 1,056 lbs, and maximum projection plate throat depth of 8.27 in. Standard 1593NA control cabinet.
The TECNA 2115F pairs a 56 kVA MFDC / inverter transformer with air-operated actuation in a projection bench welder configuration. The 2115F provides a maximum welding current of 25,000 amps, a maximum electrode force of 1,056 lbs, and a maximum projection plate throat depth of 8.27 in. The thermal current rating at 100% duty cycle is 4,800 amps. TECNA MFDC inverter technology delivers weld-to-weld repeatability and more efficient energy use than comparable single-phase AC welders. The standard 1593NA control cabinet is included. Within the MFDC bench range, the 2115F is the 56 kVA projection variant; its spot-welding counterpart at the same power class is the 2114F, which provides a 9.84-in. electrode throat instead of the 2115F’s 8.27-in. projection plate throat.
