11101101 - Tweco 11-30 Contact Tip 0.030" (Pack of 25)

Precision Tweco 11-30 Contact Tips for 0.030" Wire

The Tweco 11-30 (Part #1110-1101) is a standard contact tip designed for use with 0.030-inch (0.8mm) solid or flux-cored welding wire. As a critical component of the MIG gun front-end assembly, this contact tip is engineered to transfer welding current to the wire with minimal resistance. It belongs to the widely used 11 Series family of consumables, making it compatible with Tweco No. 1 MIG guns, as well as the popular Lincoln Magnum 100L and various other light-to-medium duty torches that utilize the 11-series form factor.

Manufactured from a high-grade copper alloy, these tips are machined to tight tolerances. The internal bore is concentric and smooth, ensuring that the wire feeds consistently without snagging or micro-arcing inside the tip, which can lead to premature failure. The 1/4"-20 UNC threaded base provides a secure mechanical and electrical connection to the gas diffuser, preventing loosening during thermal cycling. This specific model is the "Standard" version, optimized for general purpose welding applications where a balance of durability and cost-effectiveness is required.

Supplied in a package of 25, these contact tips are an essential stock item for industrial environments. Regular replacement of contact tips is necessary to maintain weld quality, as the bore eventually wears into an oval shape, causing erratic arc wandering. The Tweco 11-30 ensures that operators can maintain precise control over the weld pool by delivering a stable arc characteristic typical of genuine Tweco components.
