Rear Panel Controls & Connections

1. Power Cord - The power cord plugs into a 120VAC outlet to get input power to the ESG-1.

Outlets found on the power source are acceptable.

2. Control Cable - The control cable connects to the power source. After depressing the gun

switch on the spool gun, an internal relay on the ESG-1 provides closure between the two

wires of the control cable. This closure is then used to energize the power source.

NOTE

The control cable will have to be adapted to properly mate with the power

source I/O device.

3. Gas Valve Inlet - This is where the shielding gas hose from the gas supply is connected to

the ESG-1. The gas valve inlet controls the on/off ﬂow of shielding gas through the spool

gun assembly.

4. Primary Circuit Breaker - The circuit breaker provides protection against faults or overloads

on the primary side of the circuit.

5. Secondary Circuit Breaker - This circuit breaker provides protection against faults or

overloads on the secondary side of the circuit.
