Machine faults (error messages)
NOTE
A welding machine error is indicated by the collective fault signal lamp (A1) lighting up
and an error code (see table) being displayed in the machine control display. In the
event of a machine error, the power unit shuts down.
• If multiple errors occur, these are displayed in succession.
• Document machine errors and inform service staff as necessary.
Error message
Possible cause
Remedy
Speedometer error
Check wire guide/tube package
Err 3
Wire feed unit not connected
• Switch off cold wire mode in the device
configuration menu (off status)
• Connect wire feed unit
Temperature error
Allow machine to cool down.
Err 4
Error in emergency stop circuit
(interface for mechanised welding)
• Check the external shut-down equipment
• Check plug-in jumper JP 1 on
PCB T320/1
Err 5
Overvoltage
Err 6
Undervoltage
Switch off the machine and check mains
voltages
Err 7
Coolant error (only if cooling module
connected)
Check coolant level and refill if necessary
Err 8
Gas error
Check gas supply
Err 9
Secondary overvoltage
Err 10
PE error
Switch the machine off and on again.
If the error persists, inform the service dept.
Err 11
FastStop position
Edge "Acknowledge error" signal (0 to 1) via
robot interface (if available)
Err 16
Pilot arc current
Check welding torch
Err 17
Cold wire error
Excess current limit of a motor control
card has been triggered
Cold wire error – a permanent deviation
between wire nominal value and actual
value or a blocked drive has been
detected in the process
Inspect the wire feed system (drives, tube
packages, torch):
• Check cold wire on the torch / work piece
(moved against work piece?)
• Check relation of process wire feed
speed to robot travel speed, and correct
if necessary
• Check wire feed for stiffness with wire
inching function (resolve by checking
wire guides section by section)
Reset error via robot interface (reset error)
Err 18
Plasma gas error
Nominal value significantly different
from actual value -> No plasma gas?
Err 19
Shielding gas
Nominal value significantly different
from actual value -> No shielding gas?
• Check plasma gas supply; use the
plasma gas test function on "cold wire
feed unit" if necessary
• Check guiding / connections of the gas
supply hose for leaks / kinks
• Check that the gas supply lead of the
plasma torch is not blocked
Reset error via robot interface (reset error)
