ritmo elektra 1000 electrofusion

ELEKTRA 1000 is an high performance universal electrofusion machine, suitable for welding HDPE, PP, PP-R couplings (from 8 to 48 V).

Composed of:
- machine body surrounded by a tubular steel frame, thus creating a protective structure that gives to the welding design and functionality while also serving as transport handle and cable winding
- large graphic display that stands out for the size and resolution of the icons, making them easy to read in the setting and welding stages - intuitive control panel that simplifies and speeds up the setting of the welder
- universal connectors; no need of adapters
- GPS (on request) useful in jobsites where traceability is necessary
- a laser scanner - barcode reading system that allows the automatic setting of the welding parameters. There are nonetheless two manual settings available: by setting the welding tension/time parameters, and by introducing the numerical code indicated under the bar code, in order to recognize automatically the welding parameters
- internal memory of 4000 welds; the name of the operator among with the traditional welding data can be generated in PDF format. These reports can be downloaded to a PC through a USB port
- USB port allows updating the welder firmware, the reports download or a printer ESC-POS connection
