Tweco 1110-1311 Mig Contact Tip 0.040 Inch

Product Description

The TWECO 1110-1311 is a Velocity2a series non-threaded MIG contact tip designed for solid-wire MIG welding applications. Manufactured from solid copper, this drop-in style tip delivers a stable, low-spatter arc by optimizing electrical surface contact along the full conductor path. The centered liner design improves wire feedability and reduces erratic arc behavior. Rated for 0.040 inch wire diameter, this tip is intended for use by certified welders and fabricators on MIG welding guns equipped with Velocity-style consumable systems. Its tool-free, non-threaded design allows fast tip changes during production welding without the need for a wrench or pliers.

The 1110-1311 contact tip suits production MIG welding environments where minimizing downtime during consumable changes is a priority. The drop-in format eliminates threaded engagement, allowing the tip to be removed, rotated to expose a fresh wear surface, and reinstalled without tools. This rotational feature extends usable tip life before replacement is required. Typical installation scenarios include light industrial fabrication, structural welding, and general manufacturing operations using 0.040 inch solid or flux-cored wire on compatible TWECO Velocity2a-compatible MIG gun bodies.

Key Features

• Solid copper construction provides a continuous, low-resistance conductor path
• Non-threaded drop-in design allows tool-free tip changes
• Centered liner geometry optimizes wire feedability and arc stability
• Tip can be rotated to extend service life and reduce replacement frequency
• Reduced spatter output lowers post-weld cleanup time
• 0.040 inch wire diameter bore for precise wire-to-tip contact

Compatibility

Designed as a direct-fit replacement contact tip for TWECO Velocity2a series MIG gun consumable systems accepting non-threaded, drop-in style tips in 0.040 inch wire size.

Installation Notes

Contact tips are installed and serviced by welders and welding technicians. Always power down the welding machine and allow the gun neck to cool before changing consumables. No tools are required for this non-threaded tip — insert the tip fully into the gas diffuser until seated. Inspect the liner and diffuser for wear or contamination whenever the contact tip is replaced.
