Error messages
A welding machine error is indicated by an error code being displayed (see table) on the display
on the machine control.
In the event of a machine error, the power unit is shut down.
The display of possible error numbers depends on the machine version (interfaces/functions).
• If multiple errors occur, these are displayed in succession.
• Document machine errors and inform service staff as necessary.
Error message
Possible cause
Remedy
Err 3
Tacho error
Check wire guide/hose package
Wire feeder is not connected
• Switch off cold wire mode in the machine
configuration menu (off status)
• Connect the wire feeder
Err 4
Temperature error
Allow the machine to cool down
Error in emergency stop circuit
(interface for automated welding)
• Check the external interrupt equipment
• Check jumper JP 1 on PCB T320/1
Err 5
Overvoltage
Switch off machine and check the mains
voltage
Err 6
Low voltage
Err 7
Coolant error (with connected cooling
unit only)
Check coolant level and refill if necessary
Err 8
Gas error
Check gas supply
Err 9
Secondary overvoltage
Switch the machine off and on again.
If the error persists, contact service.
Err 10
PE error
Err 11
FastStop position
Acknowledge error via robot interface (if
available)
Err 12
VRD error
Switch the machine off and on again.
If the error persists, contact service.
Err 16
Pilot arc current
Check welding torch
Err 17
Filler wire error
Excess current or deviation of
nominal/actual wire value
Check wire feed mechanism (drive, hose
packages, torch, process wire feed speed
and robot movement speed) and adjust, if
required
Err 18
Plasma gas error
Nominal value specification differs
considerably from the actual value.
Check plasma gas supply (tightness, kinks,
guide, connections, closure)
Err 19
Shielding gas error
Nominal value specification differs
considerably from the actual value
Check plasma gas supply (tightness, kinks,
guide, connections, closure)
Err 20
Coolant flow
Coolant flow volume too low
Check cooling circuit (coolant level,
tightness, kinks, guide, connections, closure)
Err 22
Cooling circuit excess temperature
Check cooling circuit (coolant level, nominal
temperature value)
Err 23
HF choke excess temperature
• Allow the machine to cool down
• Adjust processing cycle times if
necessary
Err 24
Pilot arc ignition error
Check plasma torch consumables
Err 32
Electronics error (I>0 error)
Switch the machine off and on again.
If the error persists, contact service.
Err 33
Electronics error (Uact error)
Err 34
Electronics error (A/D channel error)
Err 35
Electronics error (edge error)
Err 36
Electronics error (S-Sign)
Err 37
Electronics error (temperature error)
Allow the machine to cool down.
