or any unregulated 24 VDC power supply at 220 watts of power. The micro-processor carriage
motor control offers operator interface of forward, stop, reverse and infinitely variable control of the
speed, within the range of the model, as well as an L.E.D. display indicating speed in either in/min.
or cm/min.
The Gullco Linear and Radial oscillator heads are compact, light weight, yet durable, reciprocating
devices with high torque, high resolution and low vibration stepper motors. They impart a linear,
pendulum or tangential motion to the welding gun. The low voltage Oscillator Control provides a
large, easy to read, multi-page graphical display and offers programmable and electronic
adjustment over the following functions:
 Oscillation
width
 Oscillation
speed
 Independent Left, centre and right dwells
 Oscillation centre positioning (steering)
 Automatic wire feed activation
 Automatic and Manual carriage travel activation
 Weld travel start delay and weld crater fill delay
 Standard (angular) or step (square) pattern oscillation
 Multiple oscillation program storage
These features enable precise control over the automated cycle generating accurate and repetitive
weld oscillation.
Adjustable bracketry as well as vertical and horizontal Micro Fine Adjustable Rack Boxes, allow the
welding gun and the oscillator head to be easily mounted, adjusted and accurately positioned, in
virtually any plane, off the front or back of the “KAT”
®
carriage.
INTENDED / FORESEEN USAGE
The Gullco “KAT”
®
Carriage/Compact Oscillator combination is used throughout the world to
automate and improve the quality and efficiency of the weld produced in automatic mechanized
welding operations. This is achieved through minimizing weld defects such as poor penetration,
incomplete fusion, overlap and undercut. Also, detrimental factors such as poor or awkward
accessibility, operator fatigue, or inconsistent workmanship are eliminated. Required quality levels
are consistently attained and productivity and profitability increased.
Welding guns are readily mounted on the oscillator head and either a linear, pendulum or tangential
motion is used to produce either a standard angular or step (square) weld pattern. The track that
the “KAT”
®
carriage is going to travel along, is positioned so that the “KAT”
®
will move the oscillator
head and welding gun along the desired path and then securely held in place using magnetic or
vacuum activated mounting devices. Safety back-up devices such as chains at the ends of the
track; or welding some track mounting devices to the work-piece; must be implemented whenever
there is a possibility that the equipment may fall due to gravity. By combining welding gun
oscillation movement with the precision controlled travel speed of the “KAT”
®
carriage, a wide range
of weld patterns can be produced....as described on the following pages.
