D-M100 - Miller AccuLock MDX Gas Diffuser for MDX-100/250 (2-Pack)

Upgrade Your MIG Gun Performance

Get the most out of your Miller MDX-100 or MDX-250 MIG gun with the genuine Miller AccuLock™ MDX Gas Diffuser (D-M100). If you are tired of dealing with erratic arcs, constant burnbacks, or the frustration of bird-nesting wire, this diffuser is the solution you have been looking for. Designed as part of the revolutionary AccuLock MDX system, this diffuser does more than just hold your contact tip—it transforms the way your wire feeds. By perfectly aligning the contact tip with the liner lock as you tighten it, the D-M100 creates a flawless, straight-line path for your welding wire. This means less friction, fewer feeding issues, and a smoother, more consistent weld bead every time you pull the trigger.

Time is money in any shop, and the AccuLock MDX diffuser is built to save you both. The coarse threading allows for lightning-fast contact tip changes, so you spend less time fumbling with parts and more time welding. Plus, the innovative tapered connection locks the tip to the diffuser and the diffuser to the neck, ensuring a tight, solid fit that won't loosen up from vibration. This solid connection also provides superior electrical conductivity, giving you a hot, stable arc even during tough jobs.

Heat is the enemy of welding consumables, but the D-M100 fights back with its unique cooling tail design. The tail of the contact tip sits inside the diffuser, where it is constantly cooled by the flow of shielding gas. This keeps your consumables lasting longer, saving you money on replacements. Sold in a convenient pack of 2, these diffusers are a must-have for any welder using the MDX series guns. Upgrade your front-end consumables today and experience the difference that precision engineering makes in your daily welding projects.
