OVERVIEW

Upgrade to Centerfire Performance with Miller 230670

Take the hassle out of your aluminum welding setup with the Miller 230670 Kit, Diffuser Centerfire DS-1AP. Designed exclusively for the Miller XR-Aluma-Pro push-pull guns, this kit allows you to convert your torch to accept Centerfire consumables. If you are tired of dealing with threaded contact tips that seize up or burn back, this conversion kit is the upgrade you have been waiting for. It brings the ease and reliability of the Centerfire system to your aluminum welding operations.

Why Switch to Centerfire?

The Centerfire system changes the game for maintenance and uptime. Unlike traditional systems that require pliers to unscrew hot tips, Centerfire tips simply drop into the diffuser and are secured by tightening the nozzle by hand. This means faster changeovers and less downtime on the shop floor. The Miller 230670 kit includes the specialized diffuser that makes this possible for the Aluma-Pro gun, ensuring you get the best possible electrical transfer and arc stability.

What is in the Box?

When you order the Miller 230670, you receive more than just a piece of brass. The kit includes the Centerfire gas diffuser and the specific head tube liners needed for the conversion. The liners are critical for smooth wire delivery, especially when pushing soft aluminum wires like 4043 or 5356. By replacing the liner in the head tube, you ensure a smooth path for the wire, reducing drag and feeding issues that frustrate welders.

Built for Professional Welders

Miller Electric is a name synonymous with quality, and this OEM kit lives up to that reputation. It is built to withstand the heat and spatter of daily industrial use. Proper gas coverage is essential for clean, x-ray quality aluminum welds, and the diffuser in this kit is designed to direct shielding gas precisely where it is needed. Don't let outdated consumables hold back your productivity; install the DS-1AP kit and experience the difference in your Aluma-Pro gun today.
