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.
