BUG-O Systems UNI-BUG II - Manual (Page 21)

4
The UNI-BUG II is a small, lightweight, versatile machine originally
designed for the shipbuilding industry to weld or cut coamings, flanges,
stiffeners 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 (101-1905 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" (51 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.
