TECNA 2112F spot bench welder — 29 kVA, air-operated, MFDC / inverter. Maximum welding current of 19,000 amps, maximum electrode force of 420 lbs, and maximum electrode throat depth of 6.3 in. Standard 1592NA control cabinet.
The TECNA 2112F pairs a 29 kVA MFDC / inverter transformer with air-operated actuation in a spot bench welder configuration. The 2112F provides a maximum welding current of 19,000 amps, a maximum electrode force of 420 lbs, and a maximum electrode throat depth of 6.3 in. The thermal current rating at 100% duty cycle is 4,000 amps. TECNA MFDC inverter technology delivers weld-to-weld repeatability and more efficient energy use than comparable single-phase AC welders. The standard 1592NA control cabinet is included. Within the MFDC bench range, the 2112F is the entry 29 kVA spot welder; its projection counterpart is the 2113F at 38 kVA.
