Plasma Tables
A CNC plasma table cuts duct fittings, flanges, and transitions straight from flat sheet using software that nests parts to waste as little metal as possible. Duct shops use them for elbows, offsets, and custom fittings that used to take hours of layout by hand. When buying, compare table size, torch quality, fume extraction, and the fitting library in the software, since the software drives most of the productivity. Used plasma tables are common and can be a smart buy, but confirm the software license transfers and the controller is still supported.
