5. Starting and operating
The instructions of this chapter are supposed to instruct you in the operation of the machine
and to lead you during the appropriate starting of the machine.
This includes:
• the safe operation of the machine
• using all the possibilities
• running the machine economically
5.1. Starting
The machine should only be operated by trained and authorized people.
For the qualification a plastic welding exam can be taken according to DVS and
DVGW.
In case of danger unplug the machine immediately.
In case of power failure, the hydraulic system can still be under pressure.
For this reason, release pressure when required.
After completion of the welding work and during breaks the machine has to be
switched off. Further be sure that no unauthorized persons have access.
Protect the machine from wetness and moisture !
Check the oil level of the hydraulic system before each starting of the control
unit in order to avoid damages on the pump. The oil level must be between the
two marks at the oil dipstick.
If necessary, add hydraulic oil of the quality HLPD 32.
The heating element surfaces must be clean, especially non greasy, therefore
they need to be cleaned shortly before each welding or in case of dirtiness by
means of a fibre-free paper and a cleaning agent (e.g. PE cleaner or pipe
cleaning tissues which are available at the WIDOS company).
The anti-adhesive coating of the heating element must remain undamaged
in the working area.
Clean the heating element only in a cold state ⇒ danger of combustion /
burning.
Take care that all hydraulic and electric connections are connected.
Take into consideration the environmental conditions:
• Welding should not be carried out in direct sunlight.
• If necessary put up a welding tent.
• In case of ambient temperatures below 5°C the following measures have to be taken:
If need be, put up a welding tent and heat up the pipe ends.
• Take measures against rain, wind and dust.
