- Operating sequences.
The following sequences reflect proper machine operation. They may be used as guidelines
for troubleshooting. After each repair, they must be carried out without encountering any error or
impediment.
Given the various operating modes available, due to the different possible configurations,
only the main sequence for each welding process is described below.
NOTE
Operations preceded by this symbol refer to operator actions.
♦
Operations preceded by this symbol refer to machine responses that must occur following an
operator action.
3.4.1
- Welding system operation.
System shut off and disconnected from the mains.
Temporarily connect a rubber hose to the (BQ) fittings of the cooling unit, thus creating a by-
pass for coolant circulation.
Connect the signal cable provided to the connectors (BD) on the wire feeder and (BS) on the
power source.
Connect the power source to the mains.
Close the switch (BU).
♦
System powered; led (H) on control panel flashes rapidly.
♦
After one second, all leds and display light on (lamp test).
♦
After one second, the display (O) reads “Art”, and display (P) reads “287”; the
displays AN1 reads PANEL, MASTER, MOTOR programs version (es.:
“04.04.04”); displays AN2 reads synergic curves programs version (es.: “SYn
1.0.0”). Then the entire control panel returns to the condition it was in before the
last shutdown.
♦
After one second, the switch (BU) is closed, the fan (512) on the power source
runs for 10 seconds, then stops.
Correct?
♦
If the cooling unit mode is set to (see Instruction Manual):
-“automatic”, the pump (125) and fans (131) run for 30 seconds then stop;
-“continuous”, the pump (125) and fans (131) run continuously;
-“OFF”, the pump (125) and fan (131) do not operate.
NO (see 3.5.1, 3.5.2, 3.5.3,
3.5.14).
YES
Press the button (AI) several times; the “Process” selection is repeated in sequence.
Press the button (AJ) several times; the “Mode” selection is repeated in sequence.
Press the button (AK) several times; the “Diameter” selection is repeated in sequence.
Press the button (AL) several times; the “Material” selection is repeated in sequence.
Press the button (AH) several times; the “accessory functions” selection is repeated in
sequence.
♦
Each time the button (AI) is pressed, the leds R (1-2-3-4-5) light in sequence.
♦
Each time the button (AJ) is pressed, the leds S, T and U light in sequence.
♦
Each time the button (AK) is pressed, the leds V light in sequence.
♦
Each time the button (AL) is pressed, the leds W and X light in sequence, the
display AN1 shows the existing programs for the type of material selected, and
the display AN2 shows the existing programs for type of gas associated with the
