6. ERROR CODES OF PANELS
By Promig 530 unit check by each start, if there are error states in the equipment; in case error
states are observed, the error state in question is shown by means of Err textes appearing on (wire
feed) display of panels (see enclosed figure).
Error codes are among others the following:
Err 1: PROMIG has gone over to MMA welding, though you have already selected MMA welding
on power source panel.
Err 2: You are pressing on start switch of gun, when data transmission between PROMIG and
PRO is broken (defect in control cable or in connector), or you are pressing on gun switch,
when MMA welding has been selected on control panel of power source.
Err 4: You are pressing on start switch of gun and selecting switch S12 for cooling mode of gun
is in liquid position and you have forgotten to switch-on the PROCOOL cooling unit or
you have forgotten to connect it to equipment.
Err 5: PROCOOL cooling unit has stopped welding. Reason can be break of supply voltage from
PROCOOL, pressure of liquid circulation doesn´t arise or temperature of cooling liquid
has arisen too high.
Err 6: Wire feed unit has stopped welding in liquid position of selecting switch S12 of air/liquid-
cooled gun for PROMIG, because data communication to cooling unit is broken (defect in
intermediate cable or in connection).
Err 7: Selecting switch S12 of air/liquid-cooled gun for PROMIG is in air position, PROCOOL
is switched-on and start switch is pressed down. Purpose of operation is to prevent the
liquid-cooled gun from being destroyed, if the selecting switch S12 for air/liquid-cooling
is in wrong position.
Err 8: Liquid-cooled PMT or WS gun is overheated.
Err 9: Overload of wire feed motor, which can be caused e.g. by blocked wire guide of gun or by
gun cable, which is too much curved.
Err 10: Operation of thermal release of PRO power source has stopped welding.
Err 11: You try to use the PMT or WS gun, when their use is prevented with the 5. jumper
operation.
Err 12: Welding has been stopped, because so colled door switch or gas guard has operated
(operations need extra mountings to standard unit).
Eliminate the error codes as follows:
Error code Err 1 is eliminated when PROMIG wire feed system is set into MIG state.
Blinking of error codes Err 2-4 ends automatically within 5 s, if the trigger is not pressed down.
Eliminate the reason of error before next start.
Blinking of error codes Err 5-12 ends by next start, if the reason of error code has been
eliminated.
