264587 - Miller 2.4mm CuCrZr Heavy Duty Contact Tip

Maximize Arc Time with the Miller 264587 CuCrZr Tip

Every welder knows that the contact tip is the unsung hero of the welding gun. It takes the most abuse, sitting right next to the molten puddle, blasting thousands of amps into the wire. When you are running heavy wire like 2.4mm, the heat and friction are intense. That is where the Miller 264587 Contact Tip shines. It isn't just a piece of copper; it is built from a Copper Chromium Zirconium (CuCrZr) alloy. Why does that matter to you? Because standard copper tips get soft when they get hot. When a tip gets soft, the wire wears out the hole into an oval shape, the arc starts to wander, and you start getting burnbacks. This CuCrZr tip stays hard even when it's red hot, keeping that wire centered and the arc focused.

If you are pushing 2.4mm wire, you are likely doing heavy structural work, hardfacing, or filling big joints. You don't have time to stop every 20 minutes to swap out a fried tip. The Miller 264587 is designed to last longer, meaning you spend more time welding and less time troubleshooting your gun. The smooth bore ensures the wire feeds consistently without snagging, which is crucial for maintaining a steady bead profile. A worn tip is the number one cause of erratic wire feeding, and upgrading to a high-end alloy tip like this is the easiest fix.

Using genuine Miller parts also guarantees that the threads will fit your diffuser perfectly and the taper will seat correctly to transfer heat away from the front end. Don't settle for generic tips that might be slightly off-spec; a poor electrical connection at the threads can heat up the whole gun. Stick with the Miller 264587 for your heavy-duty setups. It gives you the confidence that when you pull the trigger, the arc will strike instantly and run smooth, pass after pass. Whether you are in a production line or a job shop, this tip pays for itself by simply lasting longer and welding better.
