Review on RX WELD TIG Stubby Gas Lens Kit: 25PCS 17GL332 + Pyrex Cup + Alumina Nozzle - Fit DB SR WP 17 18 26 Torch by John Hill

This is my experience. I installed this gas lens and #12 glass dome on my #17 lantern. The landing was solid. The gas flow through the gas lens seemed adequate. I tested these #12 cups on 16 gauge 304 SS and the gas coverage was incredibly poor. I replaced the #8 alumina cup with the same gas lens and the welds were perfect. Reinstalled glass #12 and tried a secondary diffuser but the results were still very unsatisfactory. Installed a Furick #8 Pyrex cap on this gas lens using the same o-rings and the welds were again perfectly protected. All of these used the same cfh, amperage, cruise speed and range. My theory of poor performance has to do with the abrupt pitch and where it is in the glass. Now they are in the box and not used.
