Error messages

Depending on the options of the machine display, a fault is shown as follows:
Display type - machine control
Graphic display
two 7-segment displays
one 7-segment display
The possible cause of the fault is signalled by a corresponding fault number (see table). In the case of an
error, the power unit shuts down.
The possible error numbers displayed depend on the machine series and version!
• If multiple errors occur, these are displayed in succession.
• Document machine errors and inform service staff as necessary.
Error Possible cause
3 Tacho error
Wire feeder is not connected
4 Temperature error
Error in the emergency stop circuit
(interface for automated welding)
5 Overvoltage
6 Undervoltage
7 Coolant error (with connected cool-
ing unit only).
8 Gas error
9 Secondary overvoltage
10 PE error
11 FastStop position
12 VRD error
16 Pilot arc fault
17 Filler wire error
Excess current or deviation of the
actual value from the wire target
value.
18 Plasma gas error
Target value specification deviates
significantly from the actual value.
19
Shielding gas error
Target value specification deviates
significantly from the actual value
20
Coolant flow
Coolant flow rate too low
22 Excess temperature in cooling circuit Check cooling circuit (coolant level, temperature target
23 Excess temperature of the HF choke Allow the machine to cool. Adjust processing cycle

Remedy
Check wire guide / hose package.
Switch off cold wire mode in the machine configuration
menu (off status). Connect the wire feeder.
Allow the machine to cool.
Check the external shutdown devices. Check the
jumper JP 1 on PCB T320/1.
Switch off the machine and check the mains voltage.
Check coolant level and top up if necessary.
Check the gas supply.
Switch the machine off and on. If the error persists, no-
tify Service.
Slope "Acknowledge error" signal (0 to 1) using the ro-
bot interface (if present).
Switch the machine off and on. If the error persists, no-
tify Service.
Check welding torch.
Check the wire feed system (drives, hose packages,
welding torches, process wire feed speed and robot
travel speed) and correct if necessary.
Check plasma gas supply (leak tightness, kinks, guide,
connections, closure).
Check plasma gas supply (leak tightness, kinks, guide,
connections, closure).
Check cooling circuit (coolant level, leak tightness,
kinks, guide, connections, closure).

times if necessary.
Check the wear parts of the plasma torch.
