6. Mode Selector Switch.
The 5-position Switch (J) is used to select any one of four welding
modes, described below, or to eject the cross rail.
A. RUN: In this mode, power to the tractor is always on, and the
tractor travels continuously both during weave and dwell.
Weave speed and dwell time both affect the weld patterns.
B. STEP: The tractor travels only during dwell, and stops during
the oscillator cross stroke. Changing weave speed does not
affect the weld pattern, dwell time does.
C. TRACTOR STOP ON DWELL: This is a new mode that has
proven very advantageous in certain cases. The tractor and
oscillator travel simultaneously during the weave stroke, both
stop during dwell. Dwell time thus does not affect the weld
pattern, it controls the weld deposit on each side.
D. NO WEAVE: In this mode oscillation is stopped and only the
tractor moves, to make stringer passes.
E. Switching to the fifth position will eject the rail.

WELD PATTERNS:
When mounted on a tractor plugged into its panel, the Weaver
produces the above weld patterns; shown for increasing dwell time or
tractor speed from left to right.
