SETUP AND ALIGNMENT
Attach the rail parallel to the weld joint, with magnet bars or vacuum cups. Position the drive carriage on the
rail - see Modular Drive instructions if necessary.
Insert the welding gun into the clamp on the pendulum weaver. Adjust the racks and clamps to align the
welding gun tip with the weld joint, and tighten firmly 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 look-
ing along the shaft. Figure B shows the side view of the same.
For a fillet weld, the nozzle will be at a 45 0 angle as shown in Figure C, and will swing equally in both directions.
CAUTION: The Speed Control Card in the Pendulum
Weaver is NOT interchangeable with the speed
card in the Master Drive or Linear Weaver.
