264594 - Miller 4.0mm CuCrZr Heavy Duty Contact Tip

Maximize Uptime with the Miller 4.0mm CuCrZr Contact Tip

For professional welders tackling the biggest jobs, the Miller 264594 Contact Tip is your go-to solution for running 4.0mm wire. When you are pushing high amps and laying down serious metal, you can't afford to stop every hour to change a burned-out tip. That is why Miller engineered this tip using Copper Chromium Zirconium (CuCrZr). This premium alloy is significantly tougher than standard copper tips, meaning it stands up to the heat and abrasion of heavy wire feeding without keyholing or seizing.

We know that arc stability is everything. A worn tip causes micro-arcing inside the bore and erratic wire feeding, which leads to spatter and bad starts. The Miller 264594 keeps its shape longer, ensuring the current transfers smoothly to the wire right at the contact point. This results in a consistent, focused arc that lets you weld with confidence. It is specifically designed for single-wire setups, making it a perfect drop-in replacement for your compatible Miller heavy-duty guns or sub-arc heads.

Don't let cheap consumables bottleneck your production. Using genuine Miller parts like the 264594 ensures that your equipment runs exactly as it was designed to. Whether you are working on pressure vessels, heavy equipment repair, or structural beams, this tip gives you the durability to keep the arc on and the job moving. It’s a small part that makes a massive difference in your daily efficiency and weld quality.

Why Choose This Tip?
