TECNA TE8203D Press-Type Spot and Projection Welder
100 kVA | Air-Operated | Single-Phase AC
TECNA Model TE8203D Press-Type Spot and Projection Welder
The TECNA TE8203D is an 100 kVA, air-operated, single-phase AC press-type spot and projection 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.
