TECNA 2118D projection bench welder — 90 kVA, air-operated, MFDC / inverter. Maximum welding current of 32,000 amps, maximum electrode force of 1,654 lbs, and maximum projection plate throat depth of 9.06 in. Standard 1594W control cabinet.
The TECNA 2118D pairs a 90 kVA MFDC / inverter transformer with air-operated actuation in a projection bench welder configuration. The 2118D provides a maximum welding current of 32,000 amps, a maximum electrode force of 1,654 lbs, and a maximum projection plate throat depth of 9.06 in. The thermal current rating at 100% duty cycle is 6,400 amps. TECNA MFDC inverter technology delivers weld-to-weld repeatability and more efficient energy use than comparable single-phase AC welders. The standard 1594W control cabinet is included. Within the MFDC bench range, the 2118D is the 90 kVA projection flagship; its spot-welding counterpart at the same power class is the 2117D, which provides an 11.02-in. electrode throat instead of the 2118D’s 9.06-in. projection plate throat.
