5.2.2.2 Changing the wire feed rollers
Poor welding results due to faulty wire feeding! Wire feed rolls must be suitable for the diameter of the
wire and the material.
• Check the label of the rolls whether they fit the wire diameter.
If necessary, turn or change!
• Use V-groove rolls for steel wires and other hard wires.
• Use driven rolls with U-groove for aluminium wires and other soft, alloyed wires.
• Use driven rolls with knurled U-groove for flux cored wires.
• Slide new drive rollers into place so that the diameter of the wire used is visible on the drive roller.
• Screw the drive rollers in place with knurled screws.
