11-35 - 11-35 Contact Tips .035 (25 Pack) for Tweco #1 & Magnum 100L

Precision Engineering for MIG Welding Applications

The Tweco Style 11-35 Contact Tip is a critical consumable designed to maintain the electrical integrity and mechanical precision of your MIG welding setup. Engineered to meet the rigorous demands of industrial fabrication, this contact tip is compatible with Tweco No. 1 Series MIG guns and the widely used Lincoln Magnum 100L gun found on many compact wire feed welders. This specific model is sized for .035" (0.9mm) welding wire, a standard diameter for structural steel, automotive repair, and general maintenance applications.

Manufactured from high-quality copper alloy tubing, these tips are machined to exact specifications to ensure optimal current transfer. The electrical conductivity of the contact tip is paramount in the GMAW (MIG) process, as it is the final point of current transfer to the electrode wire before the arc is struck. Poor contact can lead to voltage drops, unstable arcs, and excessive heat buildup. The 11-35 series addresses this with a consistent inside diameter surface, held to a strict tolerance of +/- .003 inches. This precision minimizes wire wander within the tip, ensuring the wire exits centrally for accurate bead placement.

The threaded design (typically 1/4"-28 UNF) allows for a secure mechanical connection to the gas diffuser (such as the 35-50 series), preventing loosening during thermal cycling. Each tip is clearly marked with the part number and wire diameter for immediate identification in busy shop environments. Rated for applications up to 200 Amperes, these tips are robust enough for light-to-medium duty cycles while maintaining their structural integrity under heat. This 25-pack offering ensures that maintenance departments and professional welders have a reliable supply of consumables to minimize downtime associated with tip wear and burn-back.
