4 Operating and indicating elements
4.1 Elements on the standard version
No. Name Function
1 Locking fork - Heating element and planer are laid with their supporting forks
onto the clamping devices.
2 Clamping nut + spindle - Tight clamping of the pipes during the welding process.
3 Clamping cylinder
(left / right)
- Application of the welding force.
- Easy dismounting and mounting of the cylinders by
loosening or attaching the locking cotter pins.
4 Pressure gauge - Display of the hydraulic pressure.
5 Push-button - By pressing the push-button the motor switches over from 1450 rpm
up to 2900 rpm (high speed)
6 Control valve - Opening and closing the movable clamping ring,
there are four different positions:
- To the left side: movable clamping ring closes;
- In the middle (usual position): the pressure which is currently
achieved is kept (also by means of the built-in hydraulic
accumulator);
- Slightly to the right side (position pressureless): a possibly
existing pressure is released without opening the machine.
Due to the hydraulic accumulator, it takes about 10 s until
the pressure is completely released.
- To the right side: movable clamping ring opens.
7 Set screw for pressure
relief valve - Limitation of the pressure to the desired value.
8 Couplings - Connect the hydraulic hoses
9 Sockets - Connection for planer and heating element
