9SM19631 - Lincoln SP170T Aluminum U-Groove Drive Roll

Precision Aluminum Feeding for Lincoln SP170T

Welding aluminum requires precision not just in technique, but in the equipment setup. The Drive Roll for Lincoln SP170T for Aluminum is a critical component for fabricators looking to convert their standard MIG setup for aluminum applications. Standard steel drive rolls typically feature a V-groove profile which uses sharp edges to grip hard steel wires. However, when applied to soft aluminum alloys (like 4043 or 5356), these V-grooves can deform the wire cross-section, leading to excessive friction in the liner and contact tip.

This specialized drive roll features a smooth U-groove profile. The U-shape provides ample surface area contact to grip the wire without biting into it or distorting its shape. This is essential for maintaining the column strength of the wire as it is pushed through the gun cable. By preserving the wire's integrity, this drive roll significantly reduces the occurrence of "bird-nesting"—a common frustration where the wire tangles at the drive assembly—and minimizes the generation of aluminum shavings that can clog liners.

Designed specifically for the Lincoln SP170T, this component ensures a perfect fit and alignment with the wire guide and inlet. Proper alignment is paramount in aluminum welding to prevent drag. Whether you are performing automotive repairs, light fabrication, or hobbyist projects, installing the correct drive roll is the first step towards achieving professional-grade aluminum welds. This part is manufactured to meet high tolerance standards, ensuring durability and consistent performance over time.

Technical Benefits

• Non-Deforming Grip: U-groove design distributes pressure evenly around the wire.
• Reduced Friction: Smooth feeding reduces drag in the gun liner.
• Enhanced Arc Stability: Consistent wire speed translates to a steady arc and better bead appearance.
