501 Style Diffuser

The diffuser locks onto my Pro Pulse 300 with a satisfying click, and the airflow feels noticeably more focused than the stock tip. I’ve been getting a much more even spread on my welds, especially on thinner material. Definitely a solid upgrade for the price.

Took a few seconds to swap out on my Pro Pulse 220 MTS and the fit is snug with zero wobble. The water-cooled setup feels noticeably more balanced now, and the 8M cable routing stays clean through the diffuser. Exactly what I needed for those tight spots.

The airflow pattern is noticeably smoother with this 501 diffuser on my Pro Pulse 220, and it clips on without any wobble during a full day of welding. Took less than two minutes to swap out, so I've been leaving it on for most jobs now.
