the frequency of maintenance of MF. 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.

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
