• Protect by means of automatic circuit breaker (C curve) rated: 16 A for 1 Ph 220 / 230 or 10 A for 1
Ph 380 / 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
• 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 1 sec.
• 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).
• 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).
• 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.
• Either the installer or the user is responsible for checking that the welder can be properly connected;
(consult the electrical grid operator if required).
• 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.

WELDING PROCESS

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
• 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.
• For repairing doors or cases, it is necessary to connect the copper bar to the part, to prevent current
from passing through the hinges.
• Adjust time (C) for the desired operation following the values given in table (T) on Fig.1
Thermal cutout signal (E)
The warning light switched on means that the thermal protections of the welder or of the studder torch
are running.

MAINTENANCE

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.
