The TECNA 6075A-8031 is a 56 kVA, air-operated, MFDC / inverter press-type spot / projection welder with a water-cooled transformer, plates, electrode holders, and electrodes.
TECNA inverter technology offers advantages over single-phase AC, including greater welding quality and precision, more efficient use of electricity, smaller size, and less electrical loss due to impedance (power savings).

Features
- Medium-frequency welders are designed to obtain high-quality welding.
- Modular design of mechanical structure, arms, brackets, and cylinders.
- Cylinder with chrome plated stem for heavy-duty work and long life; adjustable anti-rotation device.
- Lubrication-free pneumatic components to eliminate oil mist and protect the environment.
- Adjustable double-stroke cylinder with key control.
- Built-in compressed air filter unit. Compressed air disconnection device.
- Water-cooled transformer, plates, electrode-holders, and electrodes; transformer with epoxy resin-coated windings.
- Two-stage electric foot control for clamping and welding pieces only if correctly positioned.
- Pre-setting for additional double-stage electric foot switch connection for the direct recalling of a different welding program.
- Arranged for all models: two-hand safety control with timer and removable key selector, assuring the best safety. The two-hand control device is standard on projection models only (it is available upon request on spot welder models).
- Emergency push-button to stop the machine immediately.
