Tweco 1110-1144 Mig Contact Tip 0.045 Inch Threaded

Product Description

The TWECO 1110-1144 is a threaded MIG welding contact tip machined from copper alloy tubing. It delivers consistent current transfer from the welding gun to the wire electrode, directly affecting arc stability and weld quality. The inside diameter is held to a tight tolerance of plus or minus 0.003 inches, and the bore is finished to a smooth, consistent 0.045-inch diameter. Each tip is stamped with the part number and wire diameter for quick identification at the gun. MIG welders and fabricators install this tip as a routine consumable during MIG gun maintenance.

This contact tip is suited for MIG welding applications using 0.045-inch solid or flux-core wire. It fits threaded gas diffuser styles common in MIG gun assemblies where positive tip-to-diffuser contact is required for reliable electrical conductivity. Typical use is in production welding, maintenance and repair shops, and fabrication environments where consistent arc performance and fast tip changeover matter.

Key Features

• Machined from copper alloy tubing for excellent electrical conductivity
• Inside diameter finished to 0.045 inches for consistent wire feed
• Bore tolerance held to plus or minus 0.003 inches for repeatable performance
• Threaded style ensures positive engagement with gas diffuser
• Part number and wire diameter stamped on each tip for fast identification

Compatibility

Designed as a threaded-style MIG contact tip for use with 0.045-inch wire diameter in MIG gun assemblies that accept this tip thread pattern.

Installation Notes

Contact tips are installed and serviced by welders and MIG gun technicians as standard consumable maintenance. Always power down the welding machine and allow the gun to cool before replacing a contact tip. Use the correct tip wrench or pliers to avoid cross-threading; hand-tighten snugly and then seat with a tool to ensure full contact with the gas diffuser. Inspect the diffuser and liner for wear or spatter buildup whenever a tip is changed.
