Replacing feed rolls
Replace the feed rolls when the material and diameter of the filler wire changes.
Proceed as follows:
|
1.
|
Open the top cover and lift the pressure handle. |
|
2.
|
Push the collars on the mounting pins of the feed rolls up to pull the mounting pins off. |
|
The mounting pins are different: The drive rolls' mounting pins have a circular mark on the top, while the pressure rolls' mounting pins have no marks. The pressure rolls' mounting pins have central axles attached to them, so the drive and pressure rolls' mounting pins cannot be confused with each other. |
|
3.
|
Remove the feed rolls. |
|
4.
|
Select the feed rolls according to the tables below. |
