Butt fusion welding can be managed automatically by using the DELTA DRAGON CNC system; this would eliminate any risk of error due to the operator.

It is available in two versions: SA with manual extraction of heating plate, FA with integrated mechanical extraction of heating plate. 
The CNC system is available for the Delta Dragon 250 B and 315 B models.

The gearcase it is equipped with a compact and innovative plastic casing, which can resist to the most extreme job site working conditions; particular attention was paid to the connections as well, by applying military type plugs. An easy to use software and control panel allow to view the most widely used welding standards (ISO, GIS, DVS and other).
By selecting any one of the standard and pipe diameter/SDR, all the welding parameters (pressure, time, temperature) would be automatically calculated according to the standard itself. If the chosen welding cycle is not included in the standards listed above, it is possible to manually input the welding parameters (diameter, SDR, type of material, welding time and pressure…) by simply entering the “out of standard” mode. In both cases, the machine is able to automatically manage all the phases of the welding cycle, including milling and heating control.

At the end of the welding cycle, all data are stored in the in-built memory, up to 4000 records.
Serial ports enable the operator to connect the gearcase to a portable serial printer (to obtain an immediate report) or to a PC. The gearcase is equipped with a USB port for welding report in PDF and to firmware upgrade.

The complete configuration includes:
- a linear transducer applied to the machine body
- a extractable heating element SA or FA
- hydraulic hoses with non-drip quick couplings for connecting the gearcase to the machine body
- a milling cutter
- a transducer cable for connecting the gearcase to the machine body
- a milling cutter/heating plate support
