Bug-O Systems UNI-BUG II Instructions And Parts Manual page 5

INTRODUCTION (CONT'D.)
The UNI-BUG II can operate without a track as shown below. A gear motor
turns two drive wheels on one side of the workpiece. On the other side of the
workpiece is a bracket which has four idler wheels mounted on it. An idler
screw knob is used to move the idler wheel bracket into the workpiece and
clamp it between the four idler wheels and the two drive wheels.
BUG-1855 Welding Group is required to clamp and position a welding
gun. BUG-1875 Cutting Group is available for cutting applications.

SET-UP
1. Loosen the idler screw knob to open the gap between the idler wheels and
the drive wheels. When the gap is large enough, drop the machine over
the workpiece edge.
2. The machine should be firmly resting on the front and back roller
supports and tilt forward in the direction of desired travel.
3. Engage the idler screw knob until all of the idler and drive wheels are
contacting the workpiece. Tighten another 1/2-3/4 turn to firmly clamp the
workpiece.
4. Adjust the UNI-BUG II racking attachment so the welding gun or cutting
torch is properly positioned. The are 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.
5. Set the machine speed using the speed control.
6. Set the travel switch to "ON".
7. Turn on the weld contactor switch to begin welding.
