GENERAL DESCRIPTION
The PIPE KAT
®
is an advanced portable travel carriage designed for orbital welding. It is
an electrically powered track guided carriage that travels in forward and reverse directions at
precisely controlled speeds. It consists of 24 VDC permanent magnet gear motor which
engages the aluminum pipe band (track) through the self-aligning wheel system. Pipe bands are
designed and manufactured to customer specific applications (pipe diameter). The band is
typically constructed from extruded aluminum which insures a long life and durability in harsh
conditions.
The onboard wire feeder and wire spool holder is driven by a 24 VDC motor which feeds
wire to the welding torch at precisely controlled speeds. The wire spool holder accepts standard
8” / 10 lbs [20.3cm/4.54kgs] spools.
The Gullco Linear Oscillator is a compact, light weight, yet durable, reciprocating device
with a high torque, high resolution and low vibration stepper motor. It imparts a linear motion to
the weld 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 and right dwells
Oscillation centre positioning (steering)
Multiple oscillation program storage
The precise control of these features enables accurate and repetitive weld oscillation.
The Gullco Carriage control provides control and adjustment over vertical slide, wire
feeder and carriage drive motor.
A motorized torch slide provides 2” or 50mm of tip-to-work distance adjustment, this serves as a
fine adjustment to control and maintain the proper torch to pipe height during setup and welding.
This motorized torch slide is connected to the linear oscillator by an adjustable radial Lead &
Lag mounting bracket
The versatile torch mounting bracketry provides a greater variation of torch mounting/positioning
flexibility.
INTENDED / FORESEEN USAGE
The Gullco PIPE KAT
®
is intended to automate and improve the quality of the welding
operation at precisely controlled speeds, along the Pipe Band as well as providing the interface
between the welding motion and the arc start and stop signals. The PIPE KAT
®
operates with
precise motion from start to finish regardless of the number of passes or the work pieces
involved, improving the quality, efficiency and repeatability of the process. 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.
