TECNA 4666 Press-Type Spot Welder
50 kVA – Single-Phase AC, Pneumatic-Operated Welder IN-STOCK and FOR SALE
The TECNA 4666 is a 50 kVA press-type spot welder designed with our new stationary ergonomic frame for long-term operation in demanding production environments. Furthermore, the mounted TE101 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.
- Chrome-copper electrode holders for heavy duty and long life, designed for both straight and angled fitting.
- Water-cooled epoxy resin-coated transformer.
- Water-cooled arms, electrodes, and electrode holders.
- Microprocessor control unit TECNA TE101.
- USB Port for data storage (only with TE550).
- The air-operated lubrication-free cylinder eliminates oil mist.
- Protected filter assembly with gauge.
- Two-stage electric foot pedal for clamping and welding pieces only if correctly positioned.
- Pre-connected for additional electric foot-pedal for the direct recalling of welding program No.2. This function is helpful when different kinds of welding are to be performed on the same piece.
- Adjustable electrodes stroke for max. working rate.
