The LDU printing data machines have been designed and constructed for the measurement of the butt welding parameters of PE 80,PE 100 , PP and PVDF pipes and fittings.
Besides the control function, the printing data machine gives a help to the operator during all the working phases showing on the display and advising by acoustic signal the pressure and the time to be achieved during all the cycle welding phases.
The heating mirror temperature , once the operator has set up all the pipe’s parameters, is controlled by the computer according to the material and the wall thickness.
The possibility to print in advance all the welding parameters helps the operator avoiding the use of the welding tables.
At the end of the welding a final printing allows the operator to check if the welding cycle has been done correctly.
