CHOOSING THE FEEDING ROLL
In all machines ALFA IN MIG / MAG rolls with two grooves are used. These
grooves are intended for two different wire diameters (e.g. 0,8 and 1,0 mm).
Rolls for wire feed must comply with the diameter and material of the welding
wire. Only this way a smooth wire feed can be achieved. Irregularities of the wire
feed leads to a poor quality of welding and deformation of the wire.
