Review on 🔧 AGPTEK Oxygen Regulator for CGA 540 Welding Gas Welder by Payton Luna

Instructions may be helpful but are unlikely to be necessary for an experienced operator. Came in crumpled packaging (soft envelope) and some components were unpacked but were in an envelope and undamaged. Otherwise it was in good condition and worked great. I had to get a zip tie from the hardware store to secure the hose to the fitting ($1), but it didn't make much of a difference. The only reason for four stars instead of five is the packaging.
