Esab 996999 Contact Tip .045 Medium for Gunmaster 250A

Keep Your Gunmaster 250A Running Smoothly

Every welder knows that the contact tip is the unsung hero of the MIG gun. It is the final point of contact where the welding current is transferred to the wire, and if it isn't right, your entire weld suffers. The Esab 996999 Contact Tip is the genuine replacement you need for your Gunmaster 250A or MT series MIG gun. Designed specifically for running .045" wire, this tip restores the crisp, consistent arc you expect from your Esab equipment. If you have been fighting with burnbacks, stuttering wire, or an arc that wanders, a fresh OEM contact tip is often the quickest and cheapest fix.

This specific tip is the "Medium" length version, which is the standard configuration for many Gunmaster setups. It is designed to screw perfectly into the 0558001608 gas diffuser. Why does this matter? Because a loose or ill-fitting tip creates resistance, and resistance creates heat. Excess heat destroys tips and can even damage your gun's neck. By sticking with the genuine Esab 996999, you are ensuring a tight, conductive fit that keeps the heat in the arc, not in your gun. The copper alloy used in these tips is tough enough to handle long beads without ovaling out quickly, saving you trips to the tool crib.

When you are in the middle of a job, you don't have time to second-guess your consumables. Generic tips often have sloppy bore tolerances. If the hole is too big, you lose electrical contact; if it's too tight or has burrs, the wire drags and jams. Esab's OEM manufacturing ensures that every 996999 tip is drilled perfectly for .045 wire. This means smooth feeding, less spatter to clean up, and better bead profile. It is a small part that makes a huge difference in your daily welding comfort and quality.

Whether you are fabricating heavy structural steel or doing repair work, having a stash of these tips is essential. They are the frontline defense against arc instability. Don't let a worn-out $5 part ruin a critical weld or slow down your production. Swap out your old, spatter-clogged tip with a fresh Esab 996999 and get back to laying down dimes. Compatible with both solid MIG wire and flux-cored wires of the .045" diameter, this tip is the reliable choice for professional welders using the Gunmaster platform.
