Xtrweld 14T-40 Tapered Contact Tip 0.040 Inch Mig

Product Description

The XTRWELD 14T-40 is a tapered MIG welding contact tip designed for 0.040-inch diameter wire. It is a Tweco-style consumable built to OEM specifications, providing consistent electrical contact between the wire feed and the weld puddle. The tip measures 0.250 inches in diameter and is marked with its part number and wire size for quick identification during gun maintenance. Welding technicians and fabricators install this tip as part of routine MIG gun consumable replacement to maintain arc stability and transfer efficiency.

The 14T-40 fits Tweco-style MIG guns rated from 180 amps to 450 amps. Compatible gun lines referenced in the product data include Classic, Eliminator, Weldskill, Spray Master, Smoke Master, and Supra series guns. This makes it a practical stock item for shops running multiple Tweco-compatible guns across light fabrication and heavy industrial spray transfer applications. The tapered tip profile suits applications where access geometry or wire alignment benefits from a narrowed front end.

Compatibility

Designed for Tweco-style MIG guns rated 180A to 450A, including Classic, Eliminator, Weldskill, Spray Master, Smoke Master, and Supra series. Replaces Tweco 14T series contact tips for 0.040-inch wire. Brand names are referenced for fitment identification only.

Installation Notes

Contact tip replacement is performed by welding technicians during routine MIG gun consumable service. Always de-energize the welding power source and allow the gun neck to cool before removing a worn tip. Use the appropriate tip wrench or pliers sized for the tip hex to avoid damaging the diffuser threads. Over-tightening can distort the tip bore and impair wire feed; snug-tight by hand plus a quarter turn is a standard field practice for threaded MIG tips.
