Drive Roll Kits and Wire Feeding

Drive roll kits are available for different wire types and sizes, including "U" cogged for soft wire, "U" groove for soft-shelled cored wire, and "V" groove for hard-shelled wires. Kits include necessary guides with anti-wear sleeves. Specific part numbers correspond to wire sizes ranging from .023 in. to 3/32 in. with compatibility varying between 22A and 24A models.

"U" groove drive rolls are recommended for feeding aluminum wire, with nylon wire guides available for this purpose.
