Socket Pin
Function
1
Earth (Ground)
2
Torch Switch Input (24V) to energize weld current.
(connect pins 2 & 3 to turn on welding current)
3
Torch Switch Input (0V) to energize weld current
(connect pins 2 & 3 to turn on welding current)
4
Connect pin 4 to pin 8 to instruct machine that a remote current control
device is connected (12V DC supply)
5
5k ohm (maximum) connection to 5k ohm remote control potentiometer
6
Zero ohm (minimum) connection to 5k ohm remote control
potentiometer
7
Wiper arm connection to 5k ohm remote control potentiometer
8
Connect pin 4 to pin 8 to instruct machine that a remote current control
device is connected (0V)
3
Positive Terminal
Welding current flows from the Power Source via heavy duty Dinse type terminal. It is
essential, however, that the male plug is inserted and turned securely to achieve a sound
electrical connection.
4
Negative Terminal
Welding current flows from the Power Source via heavy duty Dinse type terminal. It is
essential, however, that the male plug is inserted and turned securely to achieve a sound
electrical connection.
CAUTION 2
Loose welding terminal connections can cause overheating and result in the male plug
being fused in the bayonet terminal.
5
Gas Outlet
The Gas Outlet is a 5/8 18 UNF female gas fitting.
6
ON/OFF Switch
This switch connects the Primary supply voltage to the inverter when in the ON position.
This enables the Power Supply.
WARNING 6
When the welder is connected to the Primary supply voltage, the internal electrical
components maybe at 240V potential with respect to earth.
7
Input Cable
The input cable connects the Primary supply voltage to the equipment.
