Inserting/replac-
ing feed rollers
In order to achieve optimum wire electrode feed, the feed rollers must be suitable for the 
diameter and alloy of the wire being welded.
An overview of the feed rollers available 
and their possible areas of use can be 
found in the spare parts lists.
US devices are supplied without feed rol-
lers. After inserting the wirespool, insert the 
feed rollers.
