The UNI-BUG III is capable of continuous or intermittent stitch welds. The machine will mount and run directly on the workpiece. The unit is available in a variety of kits. Each kit is designed to fit on a specific steel profile such as a flat bar, angle, channel, I-beams and bulb flats (holland profiles). The UNI-BUG III features stitch welding which is programmable by distance. If stitch welding is required simply set the selector switch to the intermittent weld setting and program the length of weld required, the length of skip and also the required delay for pre-flow and burn back. Through the use of an integrated weld contactor, the UNI-BUG III will activate and deactivate your wire feeder automatically.
