- Medium-frequency welders are designed to obtain high-quality welding.
- The modular design of the 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. Alternatively, it may be managed by a pneumatic pedal.
- Electrodes descend without pressure for both maintenance and set-up.
- Built-in compressed air filter unit and tank. 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.
- Protection with automatic circuit breaker.
- Flow-switch which stops the machine if the cooling water does not flow and valve for blocking the water-cooling flow when the machine is off.
- (optional) USB port for data storage.
- Pneumatic circuit equipped with low force squeeze (optional), particularly suitable when projection welding and when spot welding delicate parts.
- Position sensor (optional) which allows measuring the initial thickness of the material to be welded and verifying the presence and the dimensional accuracy of the materials to be welded before welding. It also allows measuring the penetration of the electrodes at the end of the welding process. It is also possible to stop the current flow once the set penetration value has been achieved.
