087299 - Miller 087299 .023" Contact Tip (10-Pack) for M-Series Guns

Genuine Miller Performance for Precision Welding

The Miller 087299 .023" Contact Tip is a critical consumable for professional and hobbyist welders utilizing Miller M-Series MIG guns. Designed to facilitate the transfer of welding current to the wire as it passes through the gun, this contact tip is engineered to strict tolerances to ensure a stable arc and consistent wire feeding. When working with thin-gauge materials such as auto body sheet metal or light fabrication projects, the .023-inch wire diameter is a standard choice, and having a high-quality contact tip is essential to prevent micro-arcing inside the bore which can lead to erratic welds.

These contact tips are manufactured from high-grade copper, providing excellent thermal and electrical conductivity. This helps in maintaining a cool tip temperature during operation, thereby extending the life of the consumable and reducing the frequency of burn-backs. The 087299 tip features a standard 1.125-inch length and a threaded base that screws securely into the gas diffuser of M-10, M-15, M-25, and M-40 guns. This secure fit maximizes current transfer efficiency, which is vital for the smooth operation of Millermatic machines.

Compatibility is a key strength of this product. It is the standard replacement tip for a wide range of Miller power sources, including the popular Millermatic 140, Millermatic 180, Millermatic 211, and the industrial Millermatic 252. Additionally, it fits Hobart H-Series guns, making it a versatile addition to any welding shop's inventory. Sold in a convenient pack of 10, these tips ensure you always have a replacement on hand when wear occurs, keeping your production line moving without interruption.

Regular inspection and replacement of your contact tip are recommended to maintain weld quality. As the wire wears the bore into an oval shape, electrical contact becomes intermittent. Swapping to a fresh Miller 087299 tip restores the precise electrical connection needed for that signature "sizzling bacon" sound of a perfect MIG weld.
