Description
35 kVA Pneumatic Column Spot Welder c/wTE101 Microprocessor Control – 400V
The pneumatic commands and the compressed air pressure gauge have been placed at the top for easier reading and adjustment. The control unit has been positioned on the front of the machine to allow the operator to view the welding data even during the working cycle.
Key Features:
- Chrome-copper electrode holders designed for straight and angled fittings, offering long life and heavy-duty service.
- Water-cooled transformer, arms, electrodes, and electrode holders coated with epoxy resin for extended service life.
- TECNA TE101 microprocessor control unit for precise control and monitoring of the welding process.
- USB port for data storage (only available with TE550 model).
- Lubrication-free cylinder operated by air, eliminating oil mist.
- Protected filter assembly with gauge for proper filtration and monitoring.
- Two-stage electric foot control for clamping welding pieces in the correct position before welding.
- Pre-connected for an additional electric foot pedal for direct recall of welding program No.2.
- Adjustable electrode stroke for maximum working rate.
- Arms with a gap of 280mm and adjustable depth of 320mm (Option 4638).
- Compressed air pressure gauge and pneumatic commands conveniently placed at the top.
- Control unit located on the front of the machine for easy viewing and monitoring of welding data during the working cycle.
