Maintenance
ATTENTION: Before carrying out any inspection of the inside of
the welding power source, disconnect the system from the supply.
SPARE PARTS
Original spare parts have been specially designed for our equip-
ment. The use of non-original spare parts may cause variations in
performance or reduce the foreseen level of safety.
We decline all responsibility for the use of non-original spare parts.
Welding power source
As these systems are completely static, proceed as follow:
•
Periodic removal of accumulated dirt and dust from the inside of
the welding power source, using compressed air. Do not aim the
air jet directly onto the electrical components, in order to avoid
damaging them.
•
Make periodical inspections in order to individuate worn cables
or loose connections that are the cause of overheating.
Optional
The remote controls can be only used in the 2-STROKE and
4-STROKE welding modes.
MANUAL REMOTE CONTROL
WARNING: When using the welding power source for TIG weld-
ing it is obligatory to use the kit for simultaneously use – DINSE
code n° 7420900005.
Weld current can be measured at a distance by connecting up
this control. The display will show the previous maximum welding
current value set on the welder. The remote control will adjust
welding current from the minimum to this value (for further infor-
mation see page 15 in this manual). Just turn the adjustment knob
on the welder to change the maximum output value.
FOOT SWITCH
The foot switch replaces the torch button and the welding current
setting knob. The display will show the previous maximum weld
current value set on the welder. The pedal will adjust the welding
current from the minimum to this value (for further information see
the control panel manual). Just turn the adjustment knob on the
welder to change the maximum output value.
NOTE:
•
To use the pedal control correctly, set the “welding mode” to
2-STROKE and then the welding parameters SLOPE UP time
to 0 sec., SLOPE DOWN time to 0 sec.
•
When using the welding power source for TIG welding the
operator can use the torch button to start the weld and the
pedal to regulate the welding current remotely.
AIR AND/OR WATER-COOLED TORCH UP/ DOWN
The up/down torch replaces the current setting knob on the
front of the welder. Press right (+) and left (-) button to adjust the
active parameter. With this kind of torch, it is also possible to scroll
the saved programmes by pressing the two (+) and (-) buttons.
Turn the knob to scroll the programmes until an empty and unused
programme is found.
NOTE: The value shown on the display during welding represents
the effective current output with all types of control.
The digital control unit of the welding power source is fitted with a
control recognition device which allows it to identify which device
is connected and take action accordingly. To allow the command
recognition device to work correctly, connect
(with the weld-
ing power source switched off) the required accessory to the
relative connector and then switch on the welding power source
with the on/off switch.
NOTE: It is not possible to memorize or open programmes
when the remote controls are connected (except for the torch
with UP/DOWN commands).
If a remote control is connected (followed by self-acknowledge-
ment procedure) the welding power source will automatically return
to the manual-welding phase if it has been pre-set for automatic
welding.
The pointing out of any difficulties
and their elimination
The supply line is attributed with the cause of the most common
difficulties. In the case of breakdown, proceed as follows:
1) Check the value of the supply voltage
2) Check that the power cable is perfectly connected to the plug
and the supply switch
3) Check that the power fuses are not burned out or loose
4) Check whether the following are defective:
•
The switch that supplies the welding power source.
•
The plug socket in the wall.
•
The welding power source switch.
NOTE: Given the required technical skills necessary for the repair
of the welding power source, in case of breakdown we advise you
to contact skilled personnel or our technical service department.
Digital interface PCB replacement
•
Unscrew the 4 screws fastening the front rack panel.
•
Remove the adjustment knob.
•
Extract wiring connectors from digital interface PCB.
•
Unscrew small supporting columns.
•
Remove digital interface PCB by lifting it out of its supports.
•
Proceed vice versa to assemble new digital interface PCB.
Procedure for cover assembly
and disassembly
Proceed as follows (Fig. G):
1) Unscrew the two screws fastening the handle.
2) Take off handle pulling it backwards.
3) Take off covering lid and unscrew the 3 screws fastening the top.
4) Use both hands to push the top towards the front part free ing
the back part.
5) Remove top by lifting with both hands.
Proceed vice versa for assembly.
