Socket Pin Function
A
Torch Switch Input (24V) to energize weld current.
(connect pins A & B to turn ON welding current)
B Torch Switch Input (0V) to energize weld current
(connect pins A & B to turn ON welding current)
C 5k ohm (maximum) connection to 5k ohm remote control potentiometer
D Zero ohm (minimum) connection to 5k ohm remote control potentiometer
E Wiper arm connection to 5k ohm remote control potentiometer
G Mains Earth
F,H,I,J,K,L Not Used
M OK to move current detect signal for robotics applications
N OK to move current detect signal for robotics applications
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
The Gas Outlet is a BSP - 3/8 inch 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 primary potential with respect to earth.
7 Input Cable
The input cable connects the Primary supply voltage to the equipment.
8 Gas Inlet
The Gas Inlet is a BSP - 3/8 inch female gas fitting.
