Tweco 1160-1618 Mig Contact Tip 0.078 Inch Eliminator

Product Description

The TWECO 1160-1618 is an Eliminator Series MIG contact tip designed for high-amperage MIG welding applications. It accepts 5/64 inch (0.078 inch) wire and features a 0.09 inch bore ID and a 0.345 inch OD. The tip measures 1.5 inches in length and is built with a patented extended-life design intended to outlast standard contact tips under heavy use. Licensed welding technicians and fabrication professionals install this tip as a consumable replacement during routine gun maintenance or when the existing tip shows wear, burnback, or bore erosion.

This contact tip is sized and threaded specifically for use with Tweco Eliminator MIG guns rated between 250 and 650 amps. It is suited for industrial and heavy-duty fabrication environments where high-duty-cycle welding is common. The extended-life construction is particularly useful in production settings where frequent tip changes reduce throughput. It is sold individually, making it practical to stock in multiples for quick field swaps.

Compatibility

Designed for use with Tweco Eliminator MIG guns rated from 250 to 650 amps. This tip is built specifically for Eliminator-style gun heads and is not a universal-fit consumable.

Installation Notes

Contact tip replacement is performed by welding technicians as part of routine MIG gun consumable maintenance. Always power down the welder and allow the gun neck to cool completely before removing a worn tip. Use the appropriate contact tip wrench to avoid cross-threading or damaging the diffuser. Inspect the gas diffuser and nozzle for spatter buildup at the same time to maintain consistent shielding gas coverage.
