ESAB FABRICATOR 252i
Manual 0-5423 3-17 INTRODUCTION
3.14 Changing the Feed Roll
NOTE!
Feedrolls often come with a rust prohibitive coating that needs to be cleaned off before installation.
A Feedroll consists of two different sized grooves. As delivered from the factory the drive roll is installed for .035" / .045" (0.9 / 1.2
mm).
The stamped marking on the feedroll refers to the groove furthest from the stamped marking. When mounted, that will be the groove
closest to the motor and the one to thread.
To ensure proper wire feed, the groove closest to the motor must match the electrode wire size being used.

NOTE!
All grooved feed rolls have their wire size or range stamped on the side of the roll. On rolls with different
size grooves, the outer (visible when installed) stamped wire size indicates the groove in use.
Refer to feed roll kit in the Appendix for the proper selection and ordering of feed roll kits. Kit includes drive rolls, an input wire guide
and an output wire guide for a specific wire type and size.
Feed rolls are removed by twisting the feed roll retainer cap and aligning the retaining knob splines/tabs with the drive gear splines.
Feedrolls are installed by putting the feedroll onto the drive gear splines and twisting the feedroll retainer cap so that the splines/tabs
rest against the face of the feedroll where they will click into place.
NOTE!
Installation of all styles of feed rolls for the Fabricator 252i are identical..
