1. Description o product
This chapter gives important basic information about the product and its prescribed use.
All technical details of the machine are put together as a general arrangement.
1.1. General
The IDOS HRG 16, Segment has been designed for the heating element butt welding of
pipes and fittings out of PE from OD 1200 mm to OD 1600 mm.
This machine is a light-weight solid heat ring welding machine for usage particularly in
cramped problematic places.
The basic machine HRG 16 can be provided with reducer inserts (1200 - 1400 mm) for
clamping and welding smaller dimensions.
Both welding cylinders are plugged and can be combined with all HRG devices.
A second hydraulic aggregate with hydraulic clamping cylinders is optionally available.
The ring heating element is anti-stick coated, electronically controlled and supervised
according to DVS guideline 2208.
The welding cylinders with hydraulic aggregate, the clamping cylinders with hydraulic
aggregate and the electronic control apparatus for the heating element can be used with all 4
models which is a big economic advantage of the device.
All use going beyond is not purpose-oriented.
The machine is only to be used in a technically perfect condition, as well as purpose oriented,
safety- and danger-conscious in compliance with the working instructions and the relevant
safety regulations (especially the regulations for the prevention of accidents).
The described plastic welding machine may only be operated, maintained and repaired by
persons who are trained and informed about the dangers.
The manufacturer is not responsible for any damages caused by inexpert handling or
operation.
For personal injuries, material and immaterial damages resulting herefrom, only the user is
responsible!
1.2. Sa ety measures
In case of wrong use, wrong operation or wrong maintenance, the machine itself or products
standing nearby can be damaged or destroyed.
Persons being in the endangered area may be injured.
Therefore these working instructions have to be thoroughly read and the corresponding safety
regulations must be necessarily adhered to.

The plastic pipes are clamped in the clamping rings.
If the pipe ends are not plane and parallel, the front sides of the pipes should be cut plane and
parallel by means of a planer and the misalignment of the pipes is to be checked.
Then the heating element is inserted and the pipes are pressed against the heating element
under defined adjusting pressure. This process is called "adjusting".
After the prescribed bead height being reached, pressure is reduced, the heating time
begins. The function of this time is to heat up the pipe ends.
After expiration of the heating time, the slides are opened, the heating element is removed
quickly and the pipes are driven together again.
The time gap from the removal of the heating element to joining the pipes is called change
over time.
The pipes are joined under prescribed welding pressure and then cool down under pressure
(cooling time).
The welded joint can be unclamped, the welding process is finished.

5 Push-button - By pressing the push-button the motor switches over from
1380 rpm up to 2820 rpm (high speed)
6 Control valve Opening and closing of 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 depressurized): 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.

This means if e.g. the pressure of the planer is too high, it shuts off automatically.
In this case reduce the pressure on the planer and start the planer by the power switch at the
protective motor switch.
If the red control lamp lightens, the planer turns in the wrong direction.
Necessarily change the turning direction.
4.4.2. How to work with the planer
The flexible supporting fork of the planer is locked by the security bolt.
Prior to inserting the planer into the basic machine you
must turn the safety bolt for the planer support upwards
(left image)
Remove the safety bolt by pulling-out, the supporting fork is
now hanging downwards.
Suspend the planer from the ring bolt e.g. by a crane and
put it between the clamping tools in a way that the
supporting forks of the planer are locked in the supporting
forks of the basic machine.
Necessarily put the safety bolt again into the drill hole
(upon releasing the safety bolt, the handle must turn
downwards otherwise it is not applied correctly)
Switch the planer on/off by the on/off switch.
Turn and remove the safety bolt again before you remove
the planer from the basic machine and put the safety bolt
back in before inserting the planer into the reception box.

4.6. Extras: Angle setting at the clamping device
In order to weld angles, each clamping ring can be turned by max. 7,5°.
For that purpose, detach both hexagon screws (15) on the adapter plate, set the clamping ring
to the desired angle (up to 7,5°) and tighten again the hexagon screws (15).
Take care that the clamping rings do not touch each other at the top.

4.7. Special accessory: Stub end holder
In order to weld a cap or flange to a pipe you must use the stub end holder to fix the pieces.
Clamp the stub end e.g. into the left clamping tool with its front face towards the center of the
machine.
• Open the clamping tool.
• Pick up the stub end holder with belts from a
crane and place it with its stub end into the
lower clamping tool.
• Fix the stub end holder to the lower clamping
tool by three countersunk screws.
• Shut and tighten the clamping tool again.
• Fix the cap/flange onto the stub end holder
by the clamping claws.
• Mount the clamping claws according to the
outer diameter of the cap/flange onto the
stub end holder.
