I have pretty good luck cutting 1/8 inch or thicker steel with my O/A rig. When trying to cut sheet metal it runs back together and "rewelds" itself. I have moved to smaller tips, now at 00 size and have increased and decreased my Oxy pressure. It must be my travel speed or distance from tip to metal. Any thoughts would be appreciated.

Perfect. Thanks for the quick suggestions. I never thought about that much leading angle. What pressures would you recommend I try for a 00 tip?Victor Superrange II OA
