Automates Overlay/Cladding Welding Operations
The Gullco KAT®Indexing System is typically used to automate single or multi-head overlay/cladding welding operations, hard surfacing, etc. The automatic routine drives a motorized device (either the KAT®carriage or the motorized rack arm), cycling back and forth between limit switches. When the device that is cycling reaches a limit switch, it pauses, and the other motorized device starts to index the gun/torch a preset distance in a preset direction. An Arc Signal Relay is supplied with the system to provide integrated arc activation signals to the overlay/surfacing equipment. Two GSP controls, each with dedicated microprocessor chips, are used to control the automatic, two axis indexing system. One GSP control is the Cycle Control and the other is the Index Control. Each control offers user programmable parameters/variables to allow fine-tuning and functional control of the automatic cycle. Gullco Indexing Systems, enable repetitive overlay/ surfacing cycles to be preformed, with precise motion of the gun/torch from start to finish, regardless of the number of passes of the work pieces involved.
Main Components: KAT®Travel Carriage (Flex KAT®for use on flexible track of Rigid KAT®for use on rigid track), KAT®Carriage/Indexer controls, Motorized Indexer Rack Box, Heavy Duty Rack Arm, Control Cable, Limit Switch activators for Carriage and Rack Arm, Torch Holder for standard MIG gun.

KAT® Tracker Electronic Seam Tracking System
...high precision tracking system that maintain the torch in optimum operating position regardless of variations in the weld seam...providing improved quality and efficiency in a wide variety of welding operations.
The quality and efficiency achieved with today's automated welding systems can be impaired by material warpage, misalignment, irregular edge fit-up, different material thickness and other conditions that cause variations in the weld seam.
Gullco KAT® Tracker restore optimum performance when these conditions are encountered. They continually sense the slightest variation across the weld seam and automatically correct the position of the weld torch.
The trackers are designed for incorporation and use with the Gullco KAT® travel carriage system but can readily be used with other travelling and rotating devices employed in automated welding operations.
The systems are effectively employed to cut costs and increase productivity in a wide range of applications such as tank, pressure vessel, pipe and structural component fabrication and deep groove welding operations.
Gullco Kat Trackers are available in standard or heavy duty models to meet virtually all requirements. A brief description of each is provided below.
Kat Trackers are precise, dependable and highly versatile. They can be used with a wide range of Gullco accessories/ systems such as oscillators, bridge units, multiple torch assemblies etc. Contact Gullco with your requirement.
These Trackers provide precise right/left and vertical/ horizontal tracking plus...
- Electronic "End of Plate Detection" - puts the tracking system on "hold"; Preventing the torch from driving into the plate and allowing welding to continue to the plate edge.
- Electronic "Tack Detection" - interrupts the automatic tracking action when a tack-weld is encountered preventing the torch from rising prematurely...and returns the system to normal action when it reaches the end of the tack weld.
The E.A.H.S works by measuring welding current, comparing it to a target value that has been set by the operator and automatically adjusting the height of the welding gun to maintain the target welding current. The Model GK-203-400 is a standalone unit meaning it does not interface with the wire feeder. The arc activation trigger signal of the welding equipment that is used to start/stop the welding process must come from a separate piece of equipment, for example customer supplied control of other Gullco equipment. This advanced Electronic Arc Height Sensor package uses Gullco's sophisticated, yet easy to operate remote pendant control, in conjunction with a 4" linear slide assembly and current sensing control box, to provide precision arc height control during the welding process. Welding guns are readily mounted on the linear slide. This equipment is intended to automatically control the torch height throughout the welding process. The longitudinal movement can be obtained from either the work piece traveling while the linear remains stationary, or, by a travel carriage such as the Gullco KAT carriage carrying the E.A.H.S equipment down the length of the work piece which is the norm. Combining the welding gun height control with the precision controlled travel speed of the KAT carriage will allow high quality workmanship to be produced.
Gullco Mechanical Seam Trackers and Height Sensors are designed for use with the Gullco Kat Travel Carriage to accurately maintain the required, pre-set distance between the gun or torch and the workpiece in automated welding and cutting operations.
Three models are available to effectively meet various application needs. All are constant velocity, spring-type sensors utilizing hardened and ground slide bars with recirculator ball bushings to provide 1-3/4" (44mm) of torch float.
Other float distances available on request.

The Gullco vacuum mounting systems are designed to firmly hold the KAT® Rigid and Flex Tracks in position on magnetic and non-magnetic materials. The systems are rugged and dependable while incorporating a light weight design for portability. There are Vacuum/ KAT® carriage packages specifically designed for automatic welding and cutting applications.
PORTABLE VACUUM UNIT
Comprised of electric motor driven, 2.4 cfm capacity vacuum pump mounted on cylindrical safety reservoir. Complete with vacuum gauge, filter, non-return valve, necessary fittings and 10 ft. (3048 mm) of flexible hose with quick disconnect coupling. *Recommended 3 pieces of GK-165-054 Rigid or GK-192-F-054-2 Flexible Track per vacuum pump.
VACUUM MANIFOLD BLOCK MOUNTING UNIT
Comprised of two vacuum cups, manifold block and mounting pad. The manifold has openings at each end and at the centre of each side for fittings required in assemblies such as hose connectors, couplings, valves and plugs. VACUUM MANIFOLD ASSEMBLIES Link any number of Vacuum Block Mounting Units to provide a complete, in-line track mounting system. The end units are supplied with appropriate fittings for attachment to the pump or the next series of mounting units, while all "in-between" units have hose connectors on each side.
FOR MOUNTING GULLCO RIGID KAT® TRACK
Gullco can supply a ready-to-use "kit" to vacuum mount KAT® Track, providing manifold block mounting units for mounting on 30" (761 mm) centers along with all appropriate hoses, fittings, etc.
For convenience, three "Kits" are available for mounting standard 48", 96" and 120" (1219, 2438 and 3048mm) lengths of KAT® Track. They are described at right. It should be noted that these kits are supplied for use only with the designated track length.If lengths are to be joined, interconnecting fittings must be ordered.
3 lengths of 120" (3048mm) track can be handled by on vacuum pump (Model GV-168-50) depending on work surface finish.
FOR MOUNTING GULLCO KAT® FLEX TRACK
Gullco Flex-Track is 8ft. (2438 mm) and has holes for at-tachment of manifold block mounting units and stainless steel mounting brackets (photo at left). In some applications, the number of manifold block units may be safely reduced by using brackets so the number of each supplied will vary according to application requirements. For convenience, two Kits are available for vacuum mounting KAT® Flex-Track, one meeting minimum stiffness requirements, the other provid-ing standard stiffness.

The weld shaver carriage uses force compliance to allow the weld shaver head to maintain contact over contoured surfaces and ensures a consistent and precision weld removal. Force compliance technology combined with DC Servo Spindles increases:
Cutter Insert Life
The weld shaver removes up to 90% of the weld height at a rate of up to 3 ft/min (61 cm/min) and can remove welds of 0.375 - 3 Inches (0.9525 - 7.62 cm). The weld shaver system is an automated solution for the rapid removal of weld beads above a panel surface. The Weld Shaver is moved along a track by the Drive Carriage with the user managing everything remotely from the Control Console. The TWS91 System is comprised of five major components; the Track (either Flex or High-Flex), the Drive Carriage, the Weld Shaver, the Control Umbilical, and the Control Console.
