OVERVIEW

Tweco 11AH364 Standard Contact Tip - 3/64" (Pack of 25)

Equip your welding arsenal with the Tweco 11AH364 Contact Tip, the professional's choice for reliable MIG welding performance. This pack of 25 tips is designed to fit Tweco 11 Series front-end consumables, commonly found on Tweco #1 and Mini-MIG welding guns. Sized specifically for 3/64-inch (1.2mm) wire, these tips are critical for maintaining the electrical integrity of your welding arc, especially when working with aluminum or flux-cored wires that require this specific diameter.

The contact tip is arguably the most important consumable in the MIG process. It is responsible for transferring the welding current to the wire as it passes through the bore. The Tweco 11AH364 features a precision-drilled bore that balances clearance with contact area. Too tight, and the wire jams; too loose, and the arc becomes unstable. Tweco's manufacturing standards ensure this balance is perfect, reducing the frequency of burnbacks and ensuring smooth wire delivery. This is particularly important for 3/64" aluminum wire, which can be difficult to feed if the contact tip creates unnecessary drag.

Constructed from high-quality copper alloy, these tips offer excellent thermal conductivity, helping to dissipate heat away from the wire end and prolonging the life of the tip. The threaded base ensures a tight mechanical and electrical connection to the gas diffuser, preventing the voltage drops that can occur with loose-fitting generic parts. For shops that demand consistency, sticking with genuine Tweco style parts or high-quality equivalents is the best way to guarantee weld quality.

Technical Specifications:

  • Series: 11 Series (Standard Duty)
  • Wire Compatibility: 3/64" (1.2mm)
  • Thread: 1/4"-28 UNF
  • Packaging: 25 Tips per Pack

Don't let a cheap contact tip ruin your weld or damage your liner. Invest in the Tweco 11AH364 25-pack to keep your production line moving and your welds defect-free.
