Page 3: Safety Instructions
SAFETY INSTRUCTIONS Although the GK-300 “KAT” Carriage/Compact Oscillator is manufactured for safe and dependable ® operation, it is impossible to anticipate those combinations of circumstances which could result in an accident. An operator of the “KAT” Carriage/Compact Oscillator is cautioned to always practice ®... -

It is equally important to read, understand and apply the information contained within the manual. The supplemental manual (GD-075) has a title “Technical Information For The Gullco “GSP-2100” Micro-Processor Based, 24 Volt DC Motor Control”, and it’s pages are numbered with a prefix of “T- “. -
Page 5: General Description
Safety is greatly enhanced by the use of Gullco’s low voltage (24 V), highly advanced control/power supply system that is compatible with voltage inputs ranging from 85 to 264 VAC, single phase, 50/60 Hz,... - Page 6 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.

Page 7: Operation
OPERATION The electrical and mechanical installation of the “KAT” Carriage/Compact Oscillator system is ® explained in the Technical Manual (GD-098-T). Local Control Devices Carriage Motor Control Oscillator Control Fuse Holder Oscillator Head Connector Arc Activation Signal Connector (Trigger Signal) Power On/Off Switch The Power On/Off switch is used to disconnect the power to the rest of the control circuitry. - Page 8 WARNING! The motor and oscillator controls must not be continually started and stopped by the removal and reapplying of power to the controls. Turning the power off to the controls will not provide instant braking and continued use will damage the controls. Allow ten (10) seconds after the removal of power before reapplying the power to the equipment.
- Page 9 Externally, the Gullco “KAT” Control has switching for Forward/Neutral/Reverse & Run/Stop, as well ® as a rotary encoder for speed control. = “STOP” - This over-rides all other controls and when activated will apply regenerative breaking to the carriage motor to bring it to a dead stop, and will disallow any further operation of the carriage while ever it is in this state.

OSCILLATOR CONTROL A highly sophisticated, yet easy to use, multi-processor based control drives a high torque, high resolution, low vibration stepper motor located in the Oscillator Head, allowing the welding gun to be moved in a precise reciprocative manner. carriage travel and the The control interfaces with the “KAT”... - Page 11 The S rotary switch increases (clockwise adjustment) or decreases (counter-clockwise adjustment) the oscillation stroke speed. The increments of adjustment and the minimum and maximum allowable stroke speeds are dependent on the type of Oscillator Head used and the preferred units of measurement (see the Technical Manual, GD-098-T for details).

command is released to the “KAT” carriage, the carriage release icon on the lower ® right corner of the LCD screen will appear as follows: The Program push button changes the control state from running (operational) mode to programming mode, and back to running mode. While-ever the control is in programming mode, the program icon on the lower right corner of the LCD screen will appear as follows: AUTOMATIC CYCLE OPERATION... - Page 13 PROGRAMMING There are two levels of programming mode: General Programming Mode: this first level of programmable features is meant to be easily accessible to the operator and requires that the Program push button ( ) be pressed for a minimum of two (2) seconds, but no more than ten (10) seconds, while the Manual/Hold/Auto switch is either in the Manual or Hold position.
- Page 14 The sequence of level 1 (General Programming Mode) program screen displays is as follows: Rotate the A rotary switch clockwise to move forward through the screens. Rotate the A rotary switch counter-clockwise to move backwards through the screens.
- Page 15 The Features & Setup Screen Field Field Field Field Field Field The Features & Setup Screen has the following features: Field = The Auto Cycle storage number to be recalled. The number shown in this field will be the program that will be copied from storage and applied to the running (operational) mode values when exited from programming mode.
- Page 16 Hold (stop) signal is de-energized. I.e. a timing cycle to allow the arc to strike and establish, before carriage motion. The choices available are from 0.0 to 9.9 seconds in 0.1 second increments. The factory default setting is 0.3 seconds. Field = Crater Fill Delay.
- Page 17 Auto Cycle Storage Screens There are a total of ten (10) Auto Cycle Storage Screens, and each screen is identified by the “Auto Cycle Storage Number” (numbered 1 to 10) as shown in the following image. The units of measure for the oscillation width (W) and the oscillation speed (S) are programmable (level 2 - Advanced Programming Mode).

Page 18: Error Codes
ERROR CODES Error codes are displayed on the LCD screen as shown adjacent. ER.1 If the Oscillator Controls’ Manual/Hold/Auto switch is in the Auto position on power-up, the control will display ER.1 and not permit an automatic cycle to start. This prevents the undesirable start of an automatic cycle on power-up. -
