Machine faults (error messages)

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.

Possible cause
Speedometer error
Wire feed unit not connected
Temperature error
Error in emergency stop circuit
(interface for mechanised welding)
Overvoltage
Undervoltage
Coolant error (only if cooling module
connected)
Gas error
Secondary overvoltage
PE error
FastStop position
Pilot arc current
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
Plasma gas error
Nominal value significantly different
from actual value -> No plasma gas?
Shielding gas
Nominal value significantly different
from actual value -> No shielding gas?
Machine faults (error messages)
NOTE
Remedy
Check wire guide/tube package
• Switch off cold wire mode in the device
configuration menu (off status)
• Connect wire feed unit
Allow machine to cool down.
• Check the external shut-down equipment
• Check plug-in jumper JP 1 on
PCB T320/1
Switch off the machine and check mains
voltages
Check coolant level and refill if necessary
Check gas supply
Switch the machine off and on again.
If the error persists, inform the service dept.
Edge "Acknowledge error" signal (0 to 1) via
robot interface (if available)
Check welding torch
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)
• 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)
