GENERAL DESCRIPTION OF WELDING MACHINE
The machine is mainly composed by:

Version 1/2013
7
1 - BASIC MACHINE
The carriage assembly consists of one fixed jaw and two mechanically operated
movable jaws.
It is composed by an aluminium support frame, suitably treated to be resistant
to atmospheric agents, which acts as a guide, on which runs a slide to which it
is firmly anchored in the fitting (pipe).
There is a switch that regulates the correct welding depth.
A device helps the extraction of the polywelder.
The machine has a device suitable to house the closing clamps that are
interchangeable to each other depending on the diameter and the kind of pipe
and / or fitting to be welded. In this way, it is possible to weld the most of pipes,
fittings, reductions and bends on the market.
The movement of the machine is guaranteed from a dedicated tools or by
hands for precise welding.
2- POLYWELDER
The polywelder is mainly constituted by handle and heating plate.
The handle is made in order to assure a comfort, safe and effective grip, thanks
to the material used. It is able to absorb heat produced by the heating plate and
assure a perfect solidity to the whole polywelder.
The heating plate is composed by an aluminium casting with a buried electrical
resistance inside. It is equipped with a thermostat to keep the adjusted
temperature.
The plate has different holes in which can be mounted the bushes through the
supplied service keys and screws.
3 - SET OF BUSHES
The set of bushes is manufactured fully complying with the DVS 2208 standard.
They are supplied in a painted steel box with relevant screws and fastening
keys.
It is of great importance to keep bushes in good conditions in order to assure a
perfect welding. For this purpose, always store bushes properly in their box
when not used and at the end of any job, fastened in their proper housing to not
damage them during transportation. However they should be cleaned before
storing from further welding residual by using a soft cloth or paper.
Make bushes cleaning wearing anti-warm safety gloves, paying great attention.
It is ABSOLUTELY FORBIDDEN using water for cleaning and / or cooling
operation.

GENERAL WELDING CRITERIA –OPTIMAL USE
This welding machine is intended to weld pipes and / or fittings in thermoplastic
material; any other kind of use is to be considered not proper and dangerous
and shall absolute exclude the manufacturing company from any kind of
responsibility.
The welding machine 7125/LI is adjusted to be used EXCLUSIVELY with the
extractable polywelder 10125/TF with the bushes supplied as standard
equipment; the use of any other kind of polywelder and / or bushes do NOT
assure a correct welding; and shall absolute exclude the manufacturing
company from any kind of responsibility.
The welding operation with the machine ART. 7125/LI is done inserting the pipe
inside the fitting, after heating the outside part of pipe and the inner part of fitting
for a stated period of time, by using the extractable polywelder 10125/TF with
bushes.
It would be good rule, before doing all welding operations, to check some
matters:
- Carefully check the efficiency and the perfect running of safety device.
- Check the operation of the mobile parts, make sure they are not locked.
- Check that all parts of the machine are mounted correctly.
- Make sure that all conditions that could affect the normal operation of the
machine and the welding are acceptable.
It is recommended to place the equipment to be able to operate freely and into
the required time, in order to avoid wrong operations that could compromise the
good welding result. It would be good rule to make some trial tests before
proceeding.
