SPARE PARTS
Original spares have been specifically designed for our equipment.
The use of spares that are not original may cause variations in the
performance and reduce the safety level of the equipment. We are
not liable for damage due to use of spare parts that are not original.
Remote controls and accessories
CONVEX 330-400-500 basic generators may be fitted out with
various remote control systems and accessories such as:
MANUAL REMOTE CONTROL CD14
This control (which must be connected to the 14-pole connector
on the welding machine’s back panel (Pos 4, Fig A) can be used
(only when using electrode welding) for remote control of the weld-
ing current.
WARNING: Potentiometers must not be at maximum when using
this remote control.
MANUAL REMOTE CONTROL RC176
This control (that must be plugged into the relevant connector on
the front panel of the HS4 drawing unit) can be used for remote
control of the parameters that are normally regulated using the
WIRE SPEED setting and WELDING VOLTAGE setting potenti-
ometers on the front panel of the HS4 drawing unit.
WARNING: Potentiometers must not be at maximum when using
this remote control.
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 machine
• The plug socket in the wall
• The generator switch
NOTE: Given the required technical skills necessary for the repair
of the generator, in case of breakdown we advise you to contact
skilled personnel or our technical service department.
Replacing the digital interface board
Proceed as follows:
• Unscrew the 4 screws fastening the front rack panel.
• Remove both the adjustment knobs.
• Unscrew the nuts and washers on the support.
• Extract wiring connectors from digital interface PCB.
• Remove the digital interface PCB by lifting it out of its supports.
• Proceed vice versa to assemble the new digital interface PCB.
