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

Precision ESAB Contact Tip for 1.2mm Wire

The ESAB 340P121069 Contact Tip is a critical component for maintaining high-quality performance in your MIG/MAG welding operations. Designed with a standard M6 thread and a length of 28mm, this tip is engineered to fit a variety of ESAB welding torches, providing a secure and electrically efficient connection. The tip is specifically bored to accommodate 1.2mm (0.045") welding wire, ensuring a precise fit that minimizes play and promotes accurate wire targeting at the weld joint.

Manufactured from E-Cu (Electrolytic Copper), this contact tip is optimized for general-purpose welding applications where good electrical conductivity and heat dissipation are paramount. E-Cu tips are the industry standard for many fabrication tasks, offering a balance of performance and cost-effectiveness. The high purity of the copper ensures that the welding current is transferred smoothly to the wire, which is essential for maintaining a stable arc and achieving consistent weld penetration. Poor conductivity at the tip can lead to micro-arcing inside the bore, which accelerates wear and causes wire feeding issues.

Regular maintenance of your MIG gun consumables is vital for productivity. As the contact tip wears, the bore can become oval-shaped (keyholing), leading to wandering arcs and poor bead placement. By replacing your tips with genuine ESAB 340P121069 units, you ensure that your equipment operates within its designed parameters. These tips are manufactured with tight tolerances to reduce friction as the wire passes through, which helps prevent bird-nesting at the feeder and ensures smooth delivery of filler metal to the puddle.

Whether you are working in automotive repair, light industrial fabrication, or general maintenance, using the correct contact tip size and material is the first step toward defect-free welds. This M6 x 28mm tip is a staple for welders using 1.2mm wire, providing the reliability ESAB is known for.
