The 11H-45 Heavy Duty Contact Tip is a premium consumable designed for professional welders who demand consistency and longevity from their MIG equipment. Compatible with Tweco® style MIG guns, including the popular Spray Master® 250 and Classic series, as well as the ESAB® Rebel™ 235ic, this tip is a versatile solution for diverse welding environments. Engineered for use with .045-inch welding wire, it supports welding applications up to 300 amperes, making it suitable for medium to heavy fabrication work.
Manufactured from a specialized copper alloy, these contact tips offer exceptional electrical properties. The manufacturing process ensures a smooth and consistent inside diameter surface, minimizing friction as the wire passes through. This reduction in friction is crucial for preventing wire chatter and burn-back, common issues that can compromise weld integrity. The heavy-duty wall thickness provides a robust thermal path, effectively drawing heat away from the contact point to extend the service life of the consumable compared to standard duty tips.
These threaded contact tips are designed to seat perfectly into standard gas diffusers, such as the Tweco 35-50 or HD52-11, ensuring a tight electrical connection. They are also compatible with Lincoln Electric® Magnum® 100L guns often found on smaller MIG machines. Sold in a pack of 25, this bulk offering ensures you have plenty of stock on hand for long shifts. Each tip is stamped with the part number and size for instant verification, streamlining your inventory management and daily setup procedures.
