The K-BUG 2000 digital, compact dual torch fillet welder is a portable straight-line travel carriage. It is designed to carry two welding guns at the same time to fillet weld both sides of a stiffener at the same time. It can hold straight barrel or gooseneck guns. By creating two continuous or intermittent “stitch” welds at a constant travel speed the K-BUG 2000 simultaneously produces high quality, uniform welds in a fraction of the time compared to manual welding.
