1.5 INTENDED AND NON INTENDED USE
The failure to observe the prescribed instructions constitutes a condition of improper use from a technical point of view
and as regards the safety of people.
Intended use conditions
Welders must only be used for welding metals keeping within the power limits given on the data plate.
Only one trained operator is allowed to use the machine with experience to handle welding equipment.
Non intended use conditions
Welders cannot be used to exert pressure or deform materials.
It is forbidden to weld materials that can generate toxic vapours or cause explosions due to heating.
1.6 DESCRIPTION OF THE PRODUCT AND HOW IT WORKS
This welder belong to the family of resistance type welding machines.
By this we mean autogenous welding obtained by pressure, without using weld material, using the thermal effect of electricity flowing
through the components to be welded (Joule effect) for heating.
The components to be welded are gripped between two electrodes with a dual purpose: to let electricity pass through and to exert
enough force for welding.
The intensity of the current, the force on the electrodes and weld time are the most important parameters for welding. Force must be
applied during the electrodes' squeeze time phases, weld time and holding time.
The welding control unit manages the welding cycle phases; the times set are given in 1/100 sec when themains frequency is 50 Hz
and 1/120 sec. when the mains frequency is 60 Hz. The main switch turns the welding machine on, which also has the function of an
emergency stop switch. Welding is started either by the lower button on the gun or the lever switch (trigger) on the studder gun.
Acting on the pressure regulator is set to the clamping force of the pneumatic clamp. On the back side is the filter for compressed air.
The welding machine is equipped with safety thermostats to stop operation if it overheats

ENVIRONMENTAL CONDITIONS

Operating clearances: The machine must be positioned to ensure working and maintenance clearances and for any emergency
situations that may arise. For this reason we recommend leaving a clearance of about 1 metre all around the machine.
Environmental characteristics: The place where the machine is going to be used must be suitably illuminated for both production
and maintenance, free from dust, acids, corrosive substances or gases, with temperatures ranging between +5°C and +40°C.
Altitude must be less than 1000 metres. Relative air humidity:
Floor: The machine must be put on a flat surface that must also be able to withstand its weight.

2.3 CONNECTION TO THE ENERGY SOURCES
Qualified personnel who can also certify their work must install the machine.
THE INSTALLER IS RESPONSIBLE FOR A CORRECT INSTALLATION AND, IN PARTICULAR, FOR THE CHOICE OF DEVICES
TO PROTECT AGAINST SHORT CIRCUITING, OVERLOADS, LEAKAGE CURRENTS IN THE CASE OF A FAILURE AND OF THE
WIRES USED TO CONNECT TO THE MAINS WHICH MUST COMPLY WITH CURRENT LAWS AND STANDARDS. THE
INSTALLER MUST ALSO CHECK THAT THE EARTHING SYSTEM, TO WHICH THE WELDING MACHINE IS CONNECTED, IS
EFFECTIVE. THE MACHINE MUST BE CONNECTED WITH A PLUG TO THE POWER SOURCE IN ORDER TO BE UNDER THE
OPERATOR SURVEILLANCE.
