مقوّس الفوهة

My nozzles were getting so clogged the arc kept wandering, and this cleared them out in seconds. The blades expand right inside the nozzle and scrape out all that baked-on slag. I've been using it every few welds and my tips are lasting way longer.

I'd been scraping my nozzle with a plain wire brush for years and it never got the slag out of the tip. These expanding blades actually reach the inside walls, and my gas flow is noticeably smoother now. Takes about ten seconds per nozzle and I'm replacing tips way less often.

The expanding blades actually get inside the nozzle and scrape out the slag that builds up, which a wire brush never touched. Takes maybe ten seconds and my tips last way longer now. Wish I'd bought one sooner.
