Installation of wire feed rollers
The proper wire feed rolls must be chosen according to the size and material of the wire.
Type 1: for hard wire, such as carbon steel wire, stainless steel wire.
Type 2: for soft wire, such as Aluminum and Aluminum alloys, also for copper and
copper alloy wire.
Type 3: for flux-cored wire

Important!
When use pressure device to adjust wire feed roll pressure, too much
pressure will cause wire crushed, and the wire coating be damaged, and it will cause the
wearing out of feed rollers and increase the wire feeding resistance. Suitable pressures
for wires of different materials and diameters are as shown in Fig. 4-7-7.
