340P121069 - ESAB M6 x 28mm Contact Tip for 1.2mm Wire - E-Cu

ESAB 340P121069 M6 Contact Tip Overview

Maximize the efficiency of your welding setup with the ESAB 340P121069 Contact Tip. This consumable is an essential replacement part for welders utilizing 1.2mm (0.045 inch) wire in their MIG operations. Featuring an M6 thread and a 28mm overall length, it is compatible with a broad range of ESAB MIG guns and torches that utilize standard M6 geometry. The tip is constructed from E-Cu (Electrolytic Copper), a material chosen for its excellent thermal and electrical properties, making it suitable for a wide array of standard welding applications.

The contact tip acts as the final transfer point for the welding current to the wire. The ESAB 340P121069 is precision-drilled to ensure optimal contact with the wire surface without causing excessive drag. This balance is crucial; too tight, and the wire jams; too loose, and the electrical transfer becomes intermittent, causing arc instability and spatter. ESAB's manufacturing process ensures concentricity and smooth internal finishes, which significantly reduces the likelihood of burn-backs and premature failure.

In professional welding environments, downtime caused by consumable failure can be costly. Using genuine ESAB parts like the 340P121069 helps mitigate these risks. The E-Cu material effectively draws heat away from the arc zone, protecting the tip from melting or deforming under normal duty cycles. While harder alloys like CuCrZr exist for high-heat applications, E-Cu remains the preferred choice for general steel fabrication due to its superior conductivity ratings.

Installation is straightforward thanks to the standard M6 threading, allowing for quick changeovers during shifts. It is recommended to check the contact tip regularly for spatter buildup and bore wear. A worn tip can cause the wire to cast off-center, affecting weld quality. Keep your welding torch performing at its peak with this reliable, high-quality contact tip designed for 1.2mm wire applications.
