1. INTRODUCTION
This manual is intended for the operator and in particular for the personnel responsible for
safety in the use of the machine.
It is therefore recommended to carefully read the contents of this manual, and in particular
those sections on precautions and methods of use, and to keep the manual in its holder in a
safe place near the machine to facilitate future consultation as and when required.
To make the manual easier to follow reference is made to diagrams from the enclosures. The
general reference is DWG. Ax.y whereby:
A indicates that the diagram is from an enclosure
x indicates the number of the enclosure
y indicates the page number of the enclosure.
2. GENERAL PRECAUTIONS
2.1 To use the machine correctly, the user must have a thorough knowledge of these user
instructions and of all the hazards related to improper use of the machine. Only expert and
authorised personnel must therefore use the machine.
2.2 Safety in the use of the machine can only be guaranteed for the functions and materials
listed in this instruction manual. PERTICI S.p.A. declines all liability if the machine is used
for purposes other than those stated and in ways that do not conform to the user
instructions.
2.3 PERTICI S.p.A. declines all liability for any matters relating to the safety, reliability and
performance of the machine if the instructions and recommendations given in this manual
are not observed, with particular reference to: assembly, use, routine and non-routine
maintenance and repair work.
2.4 The user’s electrical system must comply with EEC 64-8 standards (CENELEC HD 384,
IEC 364 - 4/41).
The manufacturer accepts no liability if the machine is not correctly connected to the
unipotential ground circuit and if protective devices co-ordinated in such a way as to
guarantee the automatic breaking of the circuit in accordance with the above stated
specifications are not installed upstream of the machine.
2.5 Only original spare parts must be used for non-routine maintenance and repair work.
2.6 For all repair work, contact the technical assistance service designated by the supplier of
the machine. Responsibility for the perfect working order of the machine rests entirely with
the user if it is repaired or maintained incorrectly by non-specialist or unauthorised
personnel.
2.7 In particular, maintenance work on the electrical equipment must be performed by specialist
or authorised personnel using original spare parts. The machine must be disconnected
from the electrical power supply before performing any of these operations.
2.8 The welding machine is designed for use in covered industrial environments; any use in
other areas relieves PERTICI S.p.A. of all liability.

2.9 The person in charge of the machine must be trained in the correct use of the machine
itself, the safety devices and accessory equipment.
2.10 The safety devices provided with the machine are already correctly installed and attached.
Both the safety devices and the entire machine must be submitted to routine and non-
routine maintenance procedures at the specified intervals.
2.11 Before starting each job and switching on the machine, make sure that there are no chips
or waste material from previous jobs on the work surface.
2.12 The operator must wear suitable clothing and use the correct safety equipment for the
type of work being performed:
Never wear bracelets or other articles, which may be caught up in the machine.
2.13 Before starting any job with the machine, ensure that there are no persons or other
potential sources of danger in the vicinity of the machine (an area of 150 cm around the
machine) (DWG. A1.4).
2.14 Make sure the electricity mains connection cable is undamaged and correctly positioned.
2.15 Do not place or use inflammable substances near the machine, as the sparks produced
may cause fires or explosions.
2.16 The operator must exercise the utmost care when enabling the pressors using the relative
selector switch, or when enabling the motor using the bi-manual switch.
2.17 Always consider the possible consequences before approaching any of the more
dangerous zones: heating plate area, pressor zone, welding seal limitation blades area.

3. CHARACTERISTICS
3.1 Description of the machine
The welding machines type WM1/LS –WM1/LS-M and WM1/LE produced by PERTICI S.p.A.
are used mainly to weld at different angles, ranging from 180° to 40°.
A) Base plate
The base plate consists of a 3-mm thick sheet bed. (TAV. A1.1)
The elements of the base plate are bent in order to obtain the maximum rigidity and are
assembled by means of an intermittent weld. The control cabinet and all other mechanical
groups composing the machine, are mounted on the base plate by means of commercial bolts
and nuts.
The machine is also supplied complete with four vibration-damping feet, which are fixed to the
lower part of the base plate and permit to place the machine on the floor.
