Travel Carriage Compact Oscillator | Kat®

Supplier: Gullco

The Kat® Carriage/Compact Oscillator combines the Gullco Kat® all-position travel carriage with a compact oscillator head and its controls.


This advanced oscillation “package” is designed to increase production and improve the quality of the weld produced in automatic mechanized welding operations by minimizing weld defects such as poor penetration, incomplete fusion, overlap and undercut.

The GK-200 Series automation carriages come with the option for linear or radial oscillation head and can be equipped for use on either rigid or flexible track.

The oscillator is available with a linear, pendulum, tangential or step (square pattern) motion to the welding gun with adjustable motorized stroke width, infinitely variable stroke speed adjustment, three independent position dwell times, motorized centre line positioning and automatic wire feed start and travel start/stop interface.

By combining welding gun oscillation movement with the precision controlled travel speed of the KAT® carriage increased weld quality and consistency can be achieved while reducing the overall production cost of the welding application. Up to 10 weld programs can be produced and stored.

Models For All-Position Flat or Curved Surface Weld Oscillation....

The KAT®  Weld Oscillation Automation Carriage is comprised of the Compact Oscillator head, controls, mounting brackets, connecting cable, 1-1/8” heavy duty micro fine rack boxes with rack arms for horizontal and vertical adjustments and standard MIG gun holder, together with a KAT® carriage for rigid track or flex track as shown above.

GK-200-F Carriages are supplied with a KAT® specifically designed for operation on spring steel KAT® Flexible Track.

GK-200-R Carriages are supplied with a KAT® specifically designed for operation on rigid aluminum KAT®  Track.

All are equipped with the Gullco micro processor-based programmable control with a closed loop feedback for complete speed accuracy regardless of load [0-100 lbs. (45kgs)] when operating in any weld position.

GK-201-100-RC Seperate Remote Controlled Compact Oscillator Assembly - Linear or Radial
This assembly is comprised of either a linear or radial oscillator head with MIG gun holder, remote control box, control cable (up to 20ft), micro fine rack boxes, rack arms: and brackets. It can be mounted on existing KAT® automation carriage, welding head manipulators, side beam carriages, etc.

Exclusive Tangential and Pendulum or Linear Motion
The oscillator heads are capable of producing three distinct motions when mounted in either the horizontal or vertical position.

Motorized Centre Line Adjustment
With independent, electronically controlled dwells (0-5sec.) at each end of the stroke and at the centre of the stroke path. The proper torch angle/position is established quickly and easily with the KAT®  oscillation heads. It’s simply a matter of tilting the oscillator, which can be adjusted side to side or forward/backward...eliminating the time consuming and generally ineffective procedure of tilting the carriage or track.

Motorized Stroke Width
Easy, precise adjustment to provide the required weld pattern.

Oscillation Speed Control
Oscillation speed electronically controlled by speed potentiometer, 140 inches per minutes (linear) 45º per second (radial).

...Combining High Precision With Exceptional Versatility

High Precision, state-of-the-art controls on the KAT® carriage automatically direct the desired forward / reverse movement or dwell of the welding gun and its oscillation motion to produce the numerous weld patterns shown below. The carriage control enables the carriage speed and direction to be pre-set and shown on its LED display in ipm or cm/min. The oscillator controls at right enable pre-setting and carriage delay / start after wire feed start, dwell times, stroke speed, stroke width, program storage and cycle start.
