TECNA 8003D Press-Type Spot Welders 60 kVA | Air-Operated | Single-Phase AC
The TECNA 8003D is a 60 kVA, air-operated, single-phase AC press-type spot welder with a water-cooled transformer, plates, electrode holders, and electrodes. The mounted TE550 control unit has been positioned to allow the operator to view welding data even during the working cycle. The pneumatic commands and the compressed air pressure gauge have been placed at the top for easier adjustment and reading.
