I am trying to cut letters out of a circle, but I want to weld the center to the outside circle. Every time I try it the letters disappear. I think I have the lines over lapping, like I am supposed to. Clearly I’m not doing it correctly. Please help me out. Thanks in advance.

Weld is not the correct tool to use to achieve what you are looking to do. You want to use ‘Subtract’ as you want to take something away from another. Have a look at this for detailed descriptions of each Boolean operation available in LightBurn.
