5. WELDFORCE ERROR CODES
The existence of possible faults in the equipment is investigated in connection with each wire feed
unit start-up. If a fault is detected, the fault in question will be indicated as an ‘Err’ message on
the (ls) panel display (see enclosed illustration).
Error code examples:
Err 1:
Not in use.
Err 2:
Press the start switch of the gun when data transfer between KWF and KPS has been disrupted
(control cable fault or connector fault).
Err 4:
Press the start switch of the gun when liquid cooling has been selected via the KWF user interface
as the gun-cooling method and the KWU cooling unit has failed to be connected.
Err 5:
The KWU cooling unit has interrupted welding. Possible causes: loss of supply voltage from KWU,
failure of fluid circulation pressure to rise, or an excessive increase in coolant temperature.
Err 6:
Not in use.
Err 7:
Not in use.
Err 8:
Overheating of liquid-cooled PMT or WS™ gun.
Err 9:
Overloading of the wire feed motor, caused by, e.g., clogging of the gun wire conduit or excessive
bending of the gun cable.
Err 10:
Welding disrupted by activation of thermal protection of KPS power source.
Err 11:
An attempt has been made to use a PMT or WS™ gun when its use is prevented by the SETUP
function.
Err 12:
Welding disrupted due to activation of the gas guard (functions require additional attachments to
the standard unit).
Err 13:
Not in use.
Err 14:
Not in use.
Resetting error codes:
Error codes Err 2-4 automatically disappears within 5 seconds if the trigger is not pressed.
The cause of the error must be eliminated before the next start-up.
Error codes Err 5-14 disappears on the next start-up if the source of the error has been removed.
