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.

Try cutting at a leading angle. Here is da Mrs.

leading angle works wonderfully as does faster cutting. if it is thin metal sheet that i don't want to warp i will go to a 000 or 00 tip with light pressure. i have found that your heat is too high when you are getting rewelds.Comment

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

I'll also have to try the leading angle next time I try thin stuff with the torch.
