8. SERVICE AND OPERATION DISTURBANCES
The amount of use and working environment should be taken into consideration when planning
the frequency of maintenance of PROMIG. Careful use and preventive maintenance will help to
ensure trouble-free operation.
Following maintenance operations should be carried out at least every six months:
Check:
– Feed roll grooves. Excessive wear of grooves causes wire feed
problems.
– Wire guide tubes. Badly worn feed rolls and wire guide tubes
should be discarded.
– Wire guide tube in the gun should be set as near the feed rolls
as possible and the wire must follow a straight line from the end
of the tube to the groove of the feed roll.
– Reel brake adjustment.
– Electrical connections:
* Oxidized couplings must be cleaned
* Loose couplings must be tightened
Clean dust and dirt from the equipment.
twice a year
When using compressed air, always protect your eyes with proper eye
protection.
In case of problems contact your KEMPPI dealer.
