SAFETY
PROTECT YOURSELF AND OTHERS FROM SERIOUS INJURY OR DEATH. KEEP
CHILDREN AWAY. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE
AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC SHOCK can kill.
1. The equipment is not waterproof.
Using the unit in a wet environment
may result in serious injury. Do not
touch equipment when wet or standing
in a wet location.
2. The unused connectors have power on
them. Always keep the unused
connectors covered with the supplied
protective panels. Operation of the
machine without the protective panels
may result in injury.
3. Never open the equipment without
rst unplugging the power cord or
serious injury may result.
4. Verify the customer-supplied power
connections are made in accordance
with all applicable local and national
electrical safety codes. If none exist,
use International Electric Code (IEC)
950.
5. Never remove or bypass the equipment
power cord ground. Verify the
equipment is grounded in accordance
with all applicable local and national
electrical safety codes. In none exist,
use International Electric Code (IEC)
950.
EQUIPMENT DAMAGE
POSSIBLE.
1. Do not plug in the power cord without
rst verifying the equipment is OFF
and the cord input voltage is the same
as required by the machine or serious
damage may result.
2. Always verify both the pinion and
wheels are fully engaged before
applying power or equipment damage
may occur.
3. Do not leave the equipment
unattended.
4. Remove from the worksite and store
in a safe location when not in use.
FALLING EQUIPMENT
can cause serious
personal injury and
equipment damage.
Faulty or careless user installation is
possible. As a result, never stand or
walk underneath equipment.
READ INSTRUCTIONS.
Read the instruction manual before
installing and using the equipment.
2
MOVING PARTS can
cause serious injury.
1. Never try to stop the pinion from
moving except by removing power
or by using the STOP control.
2. Do not remove any protective panels,
covers or guards and operate
equipment.
HIGH FREQUENCY WARNINGS
SPECIAL PRECAUTIONS ARE REQUIRED WHEN USING PLASMA,
TIG OR ANY WELDING PROCESS THAT USES HIGH FREQUENCY
TO STRIKE AN ARC.
WARNING: HIGH FREQUENCY CAN EFFECT MACHINE
OPERATION AND THEREFORE, WELD QUALITY
Read the precautions below before installing and using the equipment.
PRECAUTIONS:
1) Some plasma or welding cables are strong sources of high frequency
interference. NEVER lay a plasma or welding cable across the controls of the
machine.
2) Always physically separate the plasma or welding cable leads from the machine
cables. For example, the plasma or welding cable leads should NEVER be
bundled with a pendant cable or the machine power cord. Maximize the separa-
tion between any machine cables and the plasma or welding cables.
3) Strictly follow the grounding procedures specied for the plasma or welding unit.
NOTE: Some plasma and welding units produce exceptionally large amounts of
high frequency noise. They may require a grounding rod be driven into the earth
within six feet (2 meters) of the plasma or welding unit to become compatible
with an automatic cutting or welding process.
4) If the high frequency is produced using a spark gap, adjust the points so the gap
is as small as possible. The larger the gap, the higher the voltage and the higher
the interference.
5) Some plasma or welding units will inject high frequency interference into the AC
power line. Use separate power line branches whenever possible to power the
plasma or welding source and the machine. Do not plug them into the same
outlet box.
6) High frequency noise may enter the machine through the plasma or welding
supply remote contactor leads. Some plasma and welding sources can produce
noise spikes of up to several thousand volts. These sources are not compatible
with automated cutting and welding equipment. It is recommended that the
remote contactor leads on these plasma or welding sources not be connected to
the machine. An alternate solution is to purchase a separate remote contactor
isolation box.

BUG-6350 STAND ALONE PENDULUM WEAVER
INTRODUCTION
The Stand Alone Pendulum Weaver is meant to be a self contained machine used for weave welding.
It can be installed as part of a welding xture, or mounted on a drive carriage running on a track. It can
also be mounted directly on a BUG-O DC- I drive unit, and has provision to supply power to the DC-I.
(shown below)
The Pendulum Weaver is particularly useful for weaving llet welds in a corner joint. The Weaver box is
attached on the end of an adjustable rack, held by a rackholder that can be mounted on the front of the
drive carriage, or directly on the welding xture.
FEATURES
• High torque, low inertia motor for precise starts and stops
• Heavy duty planetary gear box with powerful output shaft for rotating welding gun and attachments
for the gun
• Uniform pendulum motion with independent control of right and left dwell times
• High motor gearing ratio, that prevents the welding gun moving by backdriving the gear train when
power is off
• Closed loop speed control for adjustable and repeatable control of critical welding parameters
• Closed loop position control to prevent drift from the center position
• Gun mounting group with adjustable linkage for accurate positioning of the gun
• Weld Contactor ON/OFF switch

SET UP AND ALIGNMENT
If using a track drive, attach the rail parallel to the weld joint with magnet bars or vacuum cups.
Position the drive carriage on the rail, mount the control box on the drive, and attach the rack
holder to the drive unit or carriage.
Position and clamp the pendulum gearbox on the rack.
Insert the welding gun into the ts-all clamp on the pendulum weaver. Adjust the racks and clamps
to align the welding gun tip with the weld joint, and clamp rmly in place.
IMPORTANT!
When the welding gun is clamped in place with the nozzle pointing into the weld groove, the
centerline of the wire must pass through the axis of the gearbox output shaft, as shown in Figure
A, which is a view looking along the shaft. Figure B shows the side view of the same.
