11601793 - Tweco M8 Contact Tip 0.045 (1.2mm) x 30mm E-Cu

Precision Tweco Contact Tip for 0.045" Wire

The Tweco 1160-1793 is a high-performance contact tip designed to meet the rigorous demands of industrial MIG welding. Engineered with a standard M8 thread and a total length of 30mm, this tip is compatible with a wide range of MIG guns and gas diffusers that utilize the M8 mounting standard. The tip is specifically bored for 0.045-inch (1.2mm) welding wire, ensuring a precise fit that promotes optimal electrical transfer from the power source to the filler metal.

Material composition is a critical factor in contact tip performance. This unit is manufactured from E-Cu (Electrolytic Copper), a material chosen for its superior electrical conductivity and thermal transfer properties. While harder alloys like CuCrZr are available for extreme heat applications, E-Cu remains the industry standard for general fabrication because it offers the best balance of conductivity and cost. High conductivity ensures that the welding current is transferred efficiently to the wire, stabilizing the arc and reducing micro-arcing inside the bore which can lead to premature failure.

The internal geometry of the 1160-1793 is machined to tight tolerances. A smooth internal bore minimizes friction as the wire feeds through, which is essential for preventing bird-nesting at the drive rolls and ensuring consistent wire stick-out. The 30mm length provides ample contact surface area for the wire, further enhancing arc stability. Whether used in automated systems or manual handheld torches, this Tweco contact tip delivers the reliability required for consistent weld quality.

Regular maintenance of contact tips is vital for quality control. As the bore wears and becomes oval-shaped, the electrical contact point shifts, causing the arc to wander. Replacing your contact tips with genuine or high-quality equivalents like the Tweco 1160-1793 ensures that your welding parameters remain constant and your production lines keep moving without unexpected downtime.
