ELECTRONIC ARC HEIGHT SENSOR (E.A.H.S.)
This manual covers the operating instructions of the following Electronic Arc Height Sensor
(E.A.H.S.):-
GK-203-400-12* (* indicates input voltage, A = 42V, B = 115V, C = 230V)
GENERAL DESCRIPTION
The Model GK-203-400-12 is a standalone unit meaning it does not interface with the customer’s
wire feeder. The arc activation trigger signal of the customer’s welding equipment that is used to
start/stop the welding process must come from a separate piece of equipment, i.e. customer
supplied control or other Gullco equipment. This advanced Electric Arc Height Sensor package
uses Gullco’s sophisticated, yet easy to use, E.A.H.S. 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.
The Gullco linear slide is compact, light weight, yet durable, linear motion device with high torque,
high resolution and low vibration stepper motor. The slide imparts a linear motion to the welding
gun. The low voltage E.A.H.S. control provides user friendly functions while minimizing set-up and
welding down time. The Gullco E.A.H.S. system offers the following functions and features:
 Lightweight and durable components to reduce operator fatigue.
 The 4” standard slide features engraved top, bottom and center marks for quick slide
position reference to aid setup.
 Standard 25 feet of remote pendant control cable means the current sensor main control
box can be kept away from the work area reducing trip hazards; an additional 25ft extension
is available.
 Easy setup and torch height calibration (teach mode).
 Sensor control box design allows the operator to use their standard existing welding cables
without any cutting or splicing that would be needed for a shunt type sensor.
 Extremely accurate arc detection within 2% to 97% of the nominal amp range.
 Slide travel speed factory set at 10 IPM [25.4cm/min], programmable range of 3 IPM
[7.6cm/min] to 17 IPM [43.2cm/min].
 Easy to use remote pendant interface.
 Coarse and fine slide adjustment.
 Built in fault code diagnostics.
These features enable precise control over the torch height, generating accurate and repetitive high
quality results.
The E.A.H.S. sensor main control box is available in three line voltage inputs; 42, 115 and 230
VAC, single phase, 50/60 Hz.
Supplied adjustable torch bracketry allows for easy mounting of any semi-automatic and automatic
machine torches.
