The EW8 is designed to automatically weld UPP Primary and Secondary Containment electrofusion fittings. Also, using the white 7A welding leads, the EW8 can be used to weld the UPP Fusion chamber riser to the chamber base. It can be used in ambient temperatures between -15°C and +45°C. Only personnel fully trained in the use and installation of the UPP system should use this equipment.

Main Features
UPP electrofusion fittings are welded using a constant current. The EW8 automatically recognises the fitting when connected and applies the correct amount of energy for a successful weld.
The EW8 takes the ambient temperature into account when calculating the energy required to weld correctly. It must therefore be allowed to reach ambient temperature before use and must be at the same temperature as the fitting to be welded. The temperature sensor is located at the rear of the unit on the right hand side.
The EW8 works on standard alternating current and either a mains connection or a generator can be used. Generators must have a rated output of at least 4kW and power input must be between 98 and 121volts at 45 to 65Hz. The EW8 has an on/off button, a weld start button and an LED display showing the weld progress. The LEDs can also show any fault conditions that may affect the weld.

Safety
The EW8 is designed for usage on construction sites and meets applicable European and International safety standards.
The machine should be handled with the care usually given to electrical equipment, especially during transport.
The machine must only be used outside of hazardous areas (zones 0, 1 and 2).
Each time it is used, check the condition of the machine, particularly the mains power cable. If any damage is discovered, contact the supplier immediately and do not use the machine.
Check the state of the welding cables before use and replace them if there is any doubt about their condition.
Always check that the power source is within the parameters shown above before using the EW8.
Never lift or pull the machine by its power cable or the welding cables. Never disconnect welding cables by pulling the cable; always pull off the connectors.
