This device meets the specific requirements of the product technical standard and is
intended for professional use in an industrial environment only. Compliance to expected
limits for human exposure to electromagnetic fields at home is not ensured.
Follow these strategies to minimise exposure to electromagnetic fields (EMF):
„ Do not place your body between the welding cables. Both welding cables should be on
the same side of your body.
„ Twist both welding cables together and secure them with tape when possible.
„ Do not wrap the welding cables around your body.
„ Connect the earth cable to the workpiece as close as possible to the area to be welded.
„ Keep your head and trunk as far as possible from the welding circuit. Do not work close to
the welder, or seated or leaning on it. Minimum distance: Fig. 7 Da = cm 50; Db = cm.20
Class A equipment
This equipment has been designed to be used in professional and industrial environments.
If this equipment is used in domestic environments and those directly connected to a
low voltage power supply network which supplies buildings used for domestic purposes,
it may be difficult to ensure compliance to electromagnetic compatibility as the result of
conducted or radiated disturbances.
Welding in conditions of risk
„ If welding needs to be done in conditions of risk (electric discharges, suffocation, the
presence of inflammable or explosive materials), make sure that an authorised expert
evaluates the conditions beforehand. Make sure that trained people are present who
can intervene in the event of an emergency. Use the protective equipment described in
5.10; A.7; A.9 of the IEC or CLC/TS 62081 technical specification.
„ If you are required to work in a position raised above ground level, always use a safety
platform.
Additional warnings
„ It is dangerous to use the spot-welder for any other purpose than that for which it is
designed (spot resistance welding).
„ Place the welding machine on a flat stable surface, and make sure that it cannot move.
It must be positioned in such a way as to allow it to be controlled during use but without
the risk of being covered with welding sparks.
„ Do not lift the welding machine. No lifting devices are fitted on the machine.
„ Do not use cables with damaged insulation or loose connections.
Description of the welding machine
Movable resistance welding system (spot-welder) with digital microprocessor control.
It allows numerous types of hot working and spot-welding on sheet metal and is made
specifically for the vehicle bodyshop and sectors with similar types of working.

Starting up
„ Connections to the mains must be made by expert or qualified personnel.
„ Make sure that the welding machine is switched off and the plug is not in the power
socket before carrying out this procedure.
„ Make sure that the power socket that the welding machine is plugged into is protected
by safety devices (fuses or automatic switch) and grounded.
„ The device must be connected only to a supply system, with an earthed 'neutral' lead.

Assembly and electrical connections
¾ Assembly the detached parts found in the packaging Fig.5 .
¾ Check that the electrical supply delivers the voltage and frequency corresponding to
the welding machine and that it is fitted with a delayed fuse suited to the maximum
delivered rated current

3) (D curve Mod.2, 4) rated: 16A for 1Ph220/230 or 10A for 1Ph380/400.
The disconnection time in case of fault must not be higher than 0.4sec (for supply network
having a nominal voltage to earth of 230V) and should be evaluated at the installation:
if, due to installation conditions, the fault current becomes too low to properly operate
the circuit breaker, the use of an additional RCD (residual current device) may become
necessary (not on TN-C systems).
TT systems
Fig.3
¾ According to IEC 60364-4-41 the installation must be protected by an RCD which
sensitivity depends upon the earth connection resistance of each installation, IEC
60364-4-41 also requires that the RCD tripping time is lower than 1sec.
¾ The earth connection resistance of the installation must be considered for the
selection of the RCD sensitivity; the maximum resistance of the protective bonding
circuit of the welding equipment is: 0.19 Ohm
The requirements set out in the IEC/EN61000-3-12 standard do not apply to this
equipment. If this equipment is connected to low voltage power supply network, either
the installer or the user is responsible for checking that this can be done (consult the
distribution system operator if required).

equipment. If this equipment is connected to low voltage power supply network, either
the installer or the user is responsible for checking that this can be done (consult the
distribution system operator if required).
L
In order to comply with the requirements set out in EN61000-3-11 (Flicker), it is
advisable to connect the welder to the supply mains interface points with a service
current capacity of >/= 100A per phase.
L
Either the installer or the user is responsible for checking that the welder can be properly
connected; (consult the electrical grid operator if required).
¾ Plug. If the welding machine is not fitted with a plug, fit a normalised plug (2P+T for
1Ph) of suitable capacity to the power cable Fig.3.
Once you have put the welding machine into operation, switch it on and carry out the
adjustments following the order shown in the description of the controls FIG.1
Studder: tecnique for use
¾ Firmly connect the copper bar to a part of the element being repaired, screwing or
clamping it on or welding a washer to the piece and using the terminal clamp as in the
fig. 4**.
** (This component may not be included with some models).
L
For repairing doors or cases, it is necessary to connect the copper bar to the part, to
prevent current from passing through the hinges.

The warning light switched on means that the thermal protection is running. Wait for
operation to be resumed and, if possible, wait a few minutes more.
Switch off the welder and remove the plug from the power socket before carrying out any
maintenance operations.
STUDDER.
Torch = check that there are no cuts or abrasions in the cable that bare the internal
conductors.
Earth = check the efficiency of connections and terminal.
Extraordinary maintenance to be carried out by expert staff or qualified electrical
mechanics periodically depending on use.
• Inspect the inside of the welder and remove any dust deposited on the electrical parts
(using compressed air) and the electronic cards (using a very soft brush and appropriate
cleaning products). • Check that the electrical connections are tight and that the insulation
on the wiring is not damaged.
