K3920-1 - Lincoln Electric Wire Sizer Replacement Dies - 0.078 in (2.0 mm)

Maintain Precision Wire Feeding with Lincoln Electric K3920-1

The Lincoln Electric K3920-1 Wire Sizer Replacement Dies are an essential maintenance component for professional welders utilizing 0.078-inch (2.0 mm) welding wire. Designed to fit compatible Lincoln Electric wire sizing tools, these dies play a critical role in the preparation of welding wire, ensuring that the wire end is perfectly shaped and sized for optimal performance.

In heavy-duty industrial welding applications, particularly with larger diameter wires, the condition of the wire tip is crucial for successful arc initiation and smooth feeding. Cutting wire often leaves a burr or a slightly deformed cross-section that can snag inside the contact tip, leading to burn-backs, erratic feeding, or premature tip wear. The wire sizer tool, equipped with these precision dies, reforms the wire end to the correct tolerance, allowing it to pass seamlessly through the contact tip.

Over time, the dies in your wire sizing tool will wear down from repeated use against hard steel or flux-cored wires. Replacing them with the K3920-1 set restores the tool's original efficiency. These dies are manufactured to Lincoln Electric's high standards, ensuring durability and exact fitment. By maintaining your wire preparation tools with genuine replacement parts, you ensure consistent weld quality and reduce downtime associated with feeding equipment troubleshooting.

Whether you are working in structural fabrication, heavy equipment manufacturing, or shipbuilding, ensuring your wire is properly prepped is a small step that makes a big difference. Invest in the K3920-1 replacement dies to keep your operations running smoothly and your arcs starting instantly.
