KP4335-364A - Drive Roll Kit, 3/64 in U-Groove Aluminum

Precision Feeding for Aluminum MIG Welding

The Lincoln Electric KP4335-364A Drive Roll Kit is an essential accessory for professionals engaged in aluminum welding. Specifically engineered for 3/64-inch (1.19 mm) aluminum wire, this kit features a specialized U-groove geometry. Unlike standard V-groove rolls designed for hard steel wires, which bite into the material to generate traction, the U-groove profile gently cradles the soft aluminum wire. This design provides the necessary friction to push the wire through the liner and gun without crushing or deforming its round shape.

Maintaing the integrity of the wire shape is crucial for stable electrical conductivity at the contact tip and for preventing mechanical feeding issues. Aluminum is prone to "birdnesting"—tangling at the feeder—when subjected to excessive pressure or friction. By using the KP4335-364A, operators can significantly reduce feeding resistance and shaving, ensuring a smooth and consistent wire delivery speed. This consistency translates directly to a more stable arc, reduced spatter, and higher quality welds.

This genuine Lincoln Electric part is manufactured to precise tolerances, ensuring perfect alignment within compatible wire feeder mechanisms. Whether you are working in marine fabrication, automotive repair, or general manufacturing, equipping your welder with the correct drive rolls is the first step toward frustration-free aluminum welding. The kit is designed for durability and easy installation, allowing for quick changeovers when switching between materials or wire sizes.

Key Features:

• Optimized for Aluminum: U-Groove shape prevents wire flattening.
• Size Specific: Precision machined for 3/64" (1.2 mm) diameter wire.
• Smooth Operation: Reduces drag and friction in the feeding system.
• OEM Reliability: Guaranteed fit for Lincoln Electric wire feeders.
