• Carry out a few welds, adjusting the voltage using the knob
G, and the force of the gun using the setting knob Q, until
the welding is perfect.
• The gun should be removed keeping it perfectly aligned
with the bolt, to avoid deforming the clamp (Fig4).
• Do not make welds to welded stud bolts.
NO NO

7 MAINTENANCE
7.1 ROUTINE
Keep all instructions and fi gures on the welding machine
clear and legible.
The mains cable and welding cables must be insulated
and in perfect condition; be careful with the tips, which fl ex:
near the connection terminals, earth clamps and gun input.
Keep the welding current connectors to sockets B and C
clean and fi rmly tightened (see Fig. 1)
The terminals for connecting to the base metal must
make good contact to avoid overheating, sparks, uneven
current circulation, damage to the components where the
pins are welded, and welding of uneven quality.
Prevent dirt, dust and fi lings from getting into the welding
machine.
Error code Problem
WARNING 1 It means that the gun start button and microswitch
are pressed at the moment the generator is turned
on.
ERROR 2 It means that the relay RL1 is faulty.
ERROR 3 It means that the relay RL1 is faulty.
ERROR 4 It means that the SCR has short circuited
ERROR 5 It means that there is a fault in the capacitor
charging circuit
ERROR 7 It means that there is a fault in the capacitor
charging circuit
WARNING TH It means that the thermal protector has tripped.
ERROR 9 It means that there is a fault in the circuit that
measures the voltage across the capacitors.
ERROR 10 It means that there is a short circuit in the
capacitor discharging circuit.

Always make sure the cooling air circulates freely.
Make sure that the fan functions properly.
Make sure that the clamps hold the stud bolts fi rmly, with
all contact springs.
The clamp must slide freely throughout its length, without
changes due to friction or foreign matter.
7.2 SPECIAL
Only qualifi ed personnel should perform maintenance.
Some functional errors are highlighted by the appearance
of an error code on the display A.
Wait at least 5 minutes after shutting off the switch E
before opening the welding machine, and unplug the plug
from the power socket.
Use a volt meter to make sure that the capacitors are
discharged.
Carefully remove any dust, metal fragments and fi lings
from the machine using compressed air to avoid damaging
or projecting metal fragments onto the electronic or
electrical parts.
Make sure that all connectors are fully inserted.
Make sure that all welding circuit terminals are fi rmly
tightened.
After making a repair, make sure to rearrange the wiring
so that there is secure insulation between the primary and
secondary sides of the machine. Do not allow wires to
come into contact with moving parts or those that heat
up during operation. Reassemble all of the clamps as they
were on the original machine, to prevent an accidental
connection between the primary and secondary circuits if
a conductor should break or disconnect.
Also remount the screws with geared washers as on the
original equipment.
