OPERATION DISTURBANCES
The amount of use and the working environment should be taken into consideration when planning the frequen-
cy of maintenance of the FEED400. Careful use and preventive maintenance will help to ensure trouble-free
operation.
The following maintenance operations should be carried out at least every six months:
Check:
The wear of the grooves of the feed rolls. Excessive wear of grooves causes
problems in wire feed.
The wear of the wire guide tubes of the wire feeder unit. Badly worn feed rolls and
wire guide tubes should be discarded.
The wire guide tube in the gun should be set as near the feed rolls as possible, but
not touching them and the wire must follow a straight line from the end of the tube
to the groove of the feed roll.
Reel brake adjustment.
Electric connections
* oxidized couplings must be cleaned
* loose couplings must be tightened
Clean dust and dirt from the equipment.
