The Tweco 11-35 (Stock No. 1110-1202) is a standard copper contact tip designed for use with 0.035-inch (0.9 mm) solid or flux-cored welding wires. Part of the widely used 11 Series, this consumable is engineered specifically for light-to-medium duty applications, most notably within Tweco No. 1 MIG guns and compatible Mini-MIG systems. The tip features a standard 1/4"-28 UNF thread, ensuring compatibility with standard 35-50 gas diffusers and similar front-end configurations found in the 11 Series ecosystem.
Manufactured from high-grade copper alloy, these tips are machined with tight tolerances to provide optimal electrical transfer to the welding wire. The bore is precision-drilled to minimize friction while maintaining sufficient contact area for consistent arc initiation and stability. The 1.0-inch overall length is standard for this series, allowing for proper nozzle recess or stick-out depending on the nozzle selected. This package contains 25 individual contact tips, suitable for high-volume fabrication environments or MRO stock replenishment.
Proper selection of contact tips is critical for minimizing micro-arcing inside the bore, which can lead to premature failure and burn-back. The 11-35 is sized specifically to accommodate the thermal expansion of .035" wire during the welding process, preventing seizing while ensuring the current transfer point remains consistent.
