Tweco 1160-1611 Mig Contact Tip 0.035 in Eliminator

Product Description

The TWECO 1160-1611 is a patented extended-life MIG contact tip from the Eliminator Series, designed specifically for high-amperage Tweco Eliminator MIG guns rated from 250 to 650 amps. The tip measures 1.5 inches in length with an inner diameter of 0.044 inches and an outer diameter of 0.345 inches, sized to accept 0.035-inch welding wire. The Eliminator Series design focuses on longer service intervals compared to standard contact tips, making it a practical choice for production welding environments where downtime from consumable changes adds up. Licensed welders and MIG welding professionals are the primary installers of this consumable.

This contact tip is intended for use with Tweco Eliminator Series MIG guns operating in the 250 to 650 amp range. It is suited for both shop and field MIG welding applications where 0.035-inch wire is the standard process wire diameter. The extended-life construction is particularly relevant in continuous or semi-automatic welding setups where consumable longevity directly affects productivity.

Installation Notes

Contact tip replacement is performed by qualified welders or MIG gun service technicians. Always power down the welding machine and allow the gun neck to cool fully before removing a worn tip. Use the appropriate tip wrench or pliers sized for the 0.345-inch outer diameter to avoid thread damage during removal or installation. Do not overtighten, as deformation of the tip bore will negatively affect wire feeding and arc stability.
