The UNI-BUG II is a small, lightweight, versatile machine originally de-
signed for the shipbuilding industry to weld or cut coamings, flanges, stiffen-
ers and similar joints. Previously this work could not be automated because
there was not enough room to mount a machine track system or the available
machines were too large to follow some of the workpiece curves or get into
tight work areas.
The UNI-BUG II is small enough to carry a cutting torch or welding gun
into tight work areas or around very tight curves without the use of a track.
The built-in carrying handle allows for easy mounting and removal at any
point along the workpiece. The UNI-BUG II can weld or cut both straight line
and on an inner radius as small as 6"(152 mm). It will travel at speeds of
4-75 ipm (102-1905 mm/min) with a 50 lb. (22.7 kg) horizontal pulling
capacity.
The UNI-BUG II is designed to run on the edge of a bar or stiffener up to
2" (50.8 mm) thick as shown below. Front and rear rollers support the
machine and tilt it forward for better control and traction. This also sets the
working direction. The machine must be turned around to weld the other
side of the workpiece.
