Tweco 1160-1778 Mig Contact Tip 1/16 Inch

Product Description

The TWECO 1160-1778 is a Velocity2a series MIG contact tip designed for use with TWECO Velocity MIG welding guns. Contact tips are consumable wear parts that guide the welding wire through the gun and transfer welding current at the point of contact. This tip is sized for 1/16 inch wire diameter. The Velocity2a design reduces the total number of thread interfaces compared to standard MIG consumables, which lowers the risk of cross-threading and seizing during replacement. The mating thread system pairs brass threads with hardened stainless steel threads, allowing faster field replacement without special tools.

This contact tip is suited for MIG welding applications in fabrication, structural, and general manufacturing environments. It is installed by welding professionals and maintenance technicians performing consumable changeovers during production or repair work. The 1/16 inch bore size makes it appropriate for lighter wire gauges used in sheet metal and thin-material welding. Sold individually, it is a direct-replacement consumable for Velocity2a compatible MIG gun assemblies.

Key Features

• 1/16 inch bore diameter for compatible wire size
• Velocity2a single-thread-interface design reduces cross-threading and seizing risk
• Brass-to-stainless steel thread pairing allows tool-free replacement
• Fixed threaded configuration maintains consistent flushness between nozzle opening and contact tip
• Sold individually as a unit consumable replacement

Compatibility

Designed for use with TWECO Velocity2a series MIG welding gun assemblies that accept 1/16 inch contact tips.

Installation Notes

Contact tip replacement is performed by welding technicians as routine consumable maintenance on MIG welding equipment. Always power down the welding machine and allow the gun to cool before handling consumables. Inspect the nozzle and diffuser for spatter buildup during each tip change. Do not overtighten the contact tip, as this can distort the bore and affect wire feed.
