Ryan ★★★★★

Slid right onto my 25 Series neck and locked in place perfectly, so I know the insulation is solid. No arcing or misalignment so far, and it’s holding up well after a full day of heavy welding.

Edward S. ★★★★★

Snapped this on my 25 Series gun and the fit is precise—no wobble or arcing issues. The insulation feels solid, and my welds have been more consistent ever since.

Christopher Q. ★★★★★

Been using this head insulator for a few weeks now and the electrical insulation is noticeably better—no more arc flickering during heavy welds. Fits perfectly on my 25 series gun and keeps everything aligned.
