Welding Vinyl Letters

What is "welding" in the vinyl world? Perhaps the most important feature in your vinyl cutter software for home decor vinyl! It is almost a requirement for doing custom interior design work (unless you prefer to purchase premade ready-to-cut vinyl designs.) Your finished vinyl designs should hang like one great big sticker, all connected in the overlapping sections.

"Welding" is a feature that allows you to take overlapping text and/or elements and combine them into one cuttable object. If the overlapping text (like loopy l's or y's) are not joined or "welded" together, the cutter will disect the intersected lines, creating little removable intersections. It is a professional feature that makes vinyl letters easier to hang and to remove.

Not all cutter softwares use the term "welding" for this "combining" or "joining" feature. Would you tell us what cutter software you use, and what term for "welding" is used? If you DON'T have a welding feature, what cutter software are you using?
