Specifically designed to fit BND300 torches, ensuring a secure and proper fit for optimal welding performance. Engineered to guide steel welding wires within the 0.8mm to 1.2mm size range, offering flexibility across a variety of MIG welding applications. The steel wound design enhances durability and resistance to wear, especially in high-use environments. It provides a long-lasting, smooth feed path for consistent performance. Guides the wire precisely through the torch lead to the tip, minimizing wire drag and feed disruptions.
