The 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. Usage and purpose-oriented use
The WIDOS ASM 315 WM is intended for the drilling of a hole into main pipes and the heating
element butt welding of pipes out of PE and PP.
Branch pipes with OD = 63 up to OD 250 mm are welded onto main pipes with OD 90 up to
OD 315 mm by means of saddle welding.
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 hereof, only the user is
responsible!
Also part of the purpose-oriented use is:
respecting all the indications of the working instructions and
performing the inspection and maintenance works.
1.2. Safety measures
In case of wrong use, wrong operation or wrong maintenance the machine itself or products
being in the surrounding 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
advice must necessarily be adhered to.
1.3. Conformity
The machine corresponds in its construction to the valid recommendations of the European
Community as well as to the corresponding European standard specifications.
The development, manufacturing and mounting of the machine were made very carefully.
1.4. Marking of the product
The product is marked by a type plate.

3. Functional description
Basically, the international and national process guidelines are to be
followed.
Drilling:
Clamp the main pipe into the left clamping tool.
In order to carry out drilling swivel the drill between both clamping tools and fix it into the right
clamping tool.
The spring load of the basic machine is deactivated.
Now drill the hole into the main pipe by means of the drill.
Afterwards, drive the drill backwards and remove it from the clamping tool.
The spring load of the basic machine is activated again.
Welding:
Put the branch pipe into the right clamping tool, align it to the main pipe and clamp it.
The cleaned and heated heating element is brought in and the pipes are pressed against the
heating element under defined adjusting force. This process is called "adjusting".
The applied force can be read on the scale.
After the prescribed bead height being reached, the force 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 slide is opened, the heating element is removed out
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 force and then cool down under pressure
(cooling time).
The welded pipes can be released, the welding process is finished.
