BUG-O Systems UNI-BUG III - Manual (Page 5)

INTRODUCTION
The UNI-BUG III 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 work piece. The UNI-BUG III can weld or cut both
straight line and on an inner radius as small as 6" (152mm). 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 III is designed
to run on the edge of a bar or stiffener up to 2" (51 mm) wide, with a minimum height of 2" (51mm).
The UNI-BUG III operates without a track as shown in the set-up diagram. A gear motor turns the
two Drive Wheels on one side of the work piece. On the opposite side of the work piece the Idler
Wheel Bracket supports four Idler Wheels. An Idler Screw Knob is used to move the Idler Wheel
Bracket into the work piece, clamping the work piece between the two Drive Wheels and the four
Idler Wheels. The Support Rollers support the machine and tilt it forward for optimal control and
traction. This also sets the working direction. The machine is to be tilted in the direction of travel
and should be turned around to weld or cut on the opposite side of the work piece. (See Set-Up
Diagram page 6)
1. Loosen the Idler Screw Knob to open the gap between the Idler Wheels and the Drive
Wheels. When the gap is large enough, position the machine on the work piece.
2. The machine should be firmly resting on the front and rear Support Rollers and tilted
forward, in the direction of travel.
3. Engage the Idler Screw Knob until the Drive Wheels and the Idler Wheels are firmly in
contact with the work piece.
4. Adjust the racking group so that the cutting torch, or welding gun is in the proper position.
The arc should always be placed below the center of the machine so that the gun or torch
can hold the same relative position as the machine moves from a straight to a curved
work section.
