PRODUCT SERIES/ MODEL: 30 mm diameter ‘V’ Grooved Drive Rolls for DuraDrive 4-30 p/n

0558001911 and AristoDrive 4-30 0558003276 Wire Feeders

SUMMARY:

The improved feed rolls have a 70 Degree V--groove angle for improved wire gripping and feedability.

The new rolls can be identified by the ‘0’ (zero) before the decimal point in the inch units embossed on

the side of the feed roll.

Example - 0.045 is a 70 degree ‘V’ groove

.045 without the ‘0’ before the decimal point has a 90 degree ‘V’ groove.

DO NOT MIX THE 90 AND 70 DEGREE ROLLS ON THE SAME DRIVE STAND. USE A MATCHED

SET (UPPERS & LOWERS) ONLY.
