BUG-O Systems Speed Weaver II - Manual (Page 12)

1. The Speed Control Knob (A) sets the traverse speed of the cross rails:
turn clockwise to increase speed. Common weaving speeds are from
“20” to “30” on the graduated dial.
2. Two Dwell Control Knobs (B, C) set the time interval that the torch
dwells at each end of the stroke - one control for each side. Dwell time can
be set from 0 to 3 seconder independently for left and right side of weave.
3. The Amplitude Control Knob (D) on the side of the machine sets the
length of the weave stroke between .125 and 2" (3 to 51 mm). The dial counter
reads 100 for every .125" (3 mm) of stroke, eg. a reading of 0300 would give
a .375" (9.5 mm) weave. The dial counter has a lever on the bottom that locks
the amplitude setting.
4. Power Controls.
Toggle Switch (E) is used to turn power ON and OFF to the machine.
Circuit Breaker (F) is rated at 0.7A (.5A for 240V) and provides protection
against overloads. If it pops up it can be reset by pushing down.
CAUTION: Find and correct the cause of overload before resetting.
5. Weld Contact Controls.
Toggle Switch (G) turns the Weld contacts ON when momentarily
pushed forward and released, and turns them OFF when pushed back.
The Weld Contacts are wired into the terminals on the “Amphenol”
Connector (H); the leads from the trigger switch on the welding gun should
be connected to the mating connector provided.
NOTE: The Weld Contacts will also shut off if the power to the Weaver is
interrupted or turned off for any reason.
