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.

Possible cause
Tacho error
Wire feeder is not connected
Temperature error
Error in emergency stop circuit
(interface for automated welding)
Overvoltage
Low voltage
Coolant error (with connected cooling
unit only)
Gas error
Secondary overvoltage
PE error
FastStop position
VRD error
Pilot arc current
Filler wire error
Excess current or deviation of
nominal/actual wire value
Plasma gas error
Nominal value specification differs
considerably from the actual value.
Shielding gas error
Nominal value specification differs
considerably from the actual value
Coolant flow
Coolant flow volume too low
Cooling circuit excess temperature
HF choke excess temperature
Pilot arc ignition error
Electronics error (I>0 error)
Electronics error (Uact error)
Electronics error (A/D channel error)
Electronics error (edge error)
Electronics error (S-Sign)
Electronics error (temperature error)
Rectifying faults
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 down
•
Check the external interrupt equipment
•
Check jumper JP 1 on PCB T320/1
Switch off machine and check the mains
voltage
Check coolant level and refill if necessary
Check gas supply
Switch the machine off and on again.
If the error persists, contact service.
Acknowledge error via robot interface (if
available)
Switch the machine off and on again.
If the error persists, contact service.
Check welding torch
Check wire feed mechanism (drive, hose
packages, torch, process wire feed speed
and robot movement speed) and adjust, if
required
Check plasma gas supply (tightness, kinks,
guide, connections, closure)
Check plasma gas supply (tightness, kinks,
guide, connections, closure)
Check cooling circuit (coolant level,
tightness, kinks, guide, connections, closure)
Check cooling circuit (coolant level, nominal
temperature value)
•
Allow the machine to cool down
•
Adjust processing cycle times if
necessary
Check plasma torch consumables
Switch the machine off and on again.
If the error persists, contact service.
Allow the machine to cool down.
