Kemppi Promig 300 Operation Instructions Manual

PROMIG 200, PROMIG 300 / 0537 – 17© KEMPPI OY5 short flashes, Err 5: PROCOOL cooling unit has stopped welding. Reason can be break ofsupply voltage from PROCOOL, pressure of liquid circulation doesn’tarise 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 S12of liquid/air-cooled gun for Promig, because data communication tocooling 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 airposition, PROCOOL is switched-on and start switch is pressed down.Purpose of operation is to prevent the liquid-cooled gun from beingdestroyed, when the selecting switch S12 for liquid/air-cooling is inwrong 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 blockedwire 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-coolingThis position is used when you are using an AIR cooled MIG gun. The equipment allowswelding when you have not connected a switched-on PROCOOL cooling unit to equipment (seealso operations of error signal lamp H11).Liquid-coolingThis position is used when you are using a liquid cooled MIG gun. The equipment stops weldingif you have not connected a switched-on PROCOOL cooling unit to equipment, Err4. (see alsooperations 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 presseddown.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 beeneliminated.3.8. WIRE INCH SWITCH S11Inside the wire reel compartment there is a switch with which you can feed filler wire withoutstarting power source and opening the gas valve. The operation is used e.g. by reel change.3.9. GAS PURGE SWITCH S13Inside the wire reel compartment there is a switch, which the gas valve can be opened withoutstarting 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 S12In the wire reel compartment there is a switch which is set according to cooling mode of MIGgun which is used.
