7.4 Selection of the appropriate feed rolls
The feed mechanism is equipment with 4 rolls. Upon delivery rolls with V-groove with a
diameter of
1.0-1.2 mm are attached. With the change of the wire diameter you have to
replace a corresponding groove. For steel and CrNi rolls with V-groove are used. If you want
to weld with flux cored wire you have to use rolls with a U-groove.
Exampels:
