The EF500 is a machine for electrofusion welding of tubes and fittings from diameter 16mm to 630mm.

With a weight of only 19Kg, the small size of EF500 contrasts with the great performance it has. On the technology used in EF electrofusion welding units, the EF500 takes it to the next level with a compact and lightweight form factor.

It is equipped with robust rubber cables capable of tolerating the most severe conditions. It has a high contrast and backlit screen, allows excellent visibility in all lighting conditions.

It fully complies with the iso international standard for electrofusion welding equipment and has automatic barcode operation.

Using the supervisor passwords you can configure the machine and change the language of the software.

The USB connection allows the transfer of data between the machine and the computer, using the pen drive memory. The Software can be quickly updated from the USB stick. This functionality allows you to renew the software without having to return the machine to technical service. Thanks to this, he always works with the latest technology in electrofusion.

The machine allows to store 2048 welds in the memory, for later download through the USB port.
