Unsatisfactory welding results due to faulty wire feeding!
The wire feed rolls must be suitable for the diameter of the wire and the material. The wire feed
rolls are colour-coded to facilitate distinction (see the Wire feed roll overview table). When
working with a wire diameter of > 1.6 mm the drive has to be converted for the wire feed kit ON WF
2,0-3,2MM EFEED
> see 10 chapter
.
