Yes, leave the speed at 1000. The slower you go, the deeper it’s going to burn into the material. (As in…all the way through.)
High Power with Fast Speeds. Low power with slow speeds. (Think about it as how long you are holding the flame against the wood. Slow keeps it burning longer, eats away more material.)
