5 short flashes, 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.
6 short flashes, Err 6: Wire feed unit has stopped welding in liquid position of selecting S12
of liquid/air-cooled gun for Promig, because data communication to
cooling unit is broken (defect in intermediate cable or in connection).
7 short flashes, Err 7: Selecting switch S12 of liquid/air-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, when the selecting switch S12 for liquid/air-cooling is in
wrong position.
8 short flashes, Err 8: Liquid-cooled MIG gun is overheated.
9 short flashes, 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.
10 short flashes, Err 10: Operation of thermal protection of PRO power source has stopped welding.
Air-cooling
This position is used when you are using an AIR cooled MIG gun. The equipment allows
welding when you have not connected a switched-on PROCOOL cooling unit to equipment (see
also operations of error signal lamp H11).
Liquid-cooling
This position is used when you are using a liquid cooled MIG gun. The equipment stops welding
if you have not connected a switched-on PROCOOL cooling unit to equipment, Err4. (see also
operations of error signal lamp H11).
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 causer of error before next start.
Blinking of error codes Err 5-10 stops by next start, if the causer of error code has been
eliminated.
3.8. WIRE INCH SWITCH S11
Inside the wire reel compartment there is a switch with which you can feed filler wire without
starting power source and opening the gas valve. The operation is used e.g. by reel change.
3.9. GAS PURGE SWITCH S13
Inside the wire reel compartment there is a switch, which the gas valve can be opened without
starting power source or wire feed motor. The operation is used e.g. by gas flow regulation.
3.10. SELECTION OF MIG GUN’S COOLING MODE S12
In the wire reel compartment there is a switch which is set according to cooling mode of MIG
gun which is used.
