Tweco 1160-1537 Mig Contact Tip 0.045 in 25 Pack

Product Description

The TWECO 1160-1537 is a standard MIG welding contact tip designed for 0.045-inch wire diameter. Machined from chrome copper, this tip provides consistent electrical conductivity and wear resistance in MIG welding applications. It measures 1.81 inches in length with a 0.054-inch bore ID and 0.375-inch OD, and threads in with M8 x 1.25 threads for secure gun attachment. Sold in a 25-count pack, the 1160-1537 is a consumable replacement item used by welding professionals requiring reliable arc performance and wire feed consistency in pulse MIG applications.

This contact tip is designed for use with Tweco PULSEMASTER MIG guns. It is suited for production welding, fabrication shops, and maintenance and repair operations where 0.045-inch solid or flux-core wire is run. The chrome copper construction handles the thermal cycling demands of continuous or semi-continuous MIG welding. Installers and welding technicians sourcing replacement consumables for Tweco PULSEMASTER-compatible torches will find this tip a direct drop-in replacement for worn or damaged tips.

Compatibility

Designed for use with Tweco PULSEMASTER MIG guns. Verify torch thread pattern and tip seat geometry before installation to confirm fitment with your specific gun model.

Installation Notes

Contact tip replacement is performed by welding technicians as part of routine consumable maintenance. Always power down the welder and allow the gun to cool completely before removing a worn tip. Use the appropriate tip wrench to avoid cross-threading the M8 x 1.25 threads. Do not overtighten, as deformation of the tip or gun body can affect wire feed and arc stability.
