The 14 pin Remote Control Socket
is used to connect remote current
control devices to the welding Power
Source. To make connections,
align keyway, insert plug, and rotate
threaded collar fully clockwise.
Socket Pin Function
A
Torch Switch Input (24V) to energise weld current.
(connect pins A & B to turn on welding current)
B Torch Switch Input (0V) to energise 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
F Connect pin 4 to pin 8 to instruct machine that a remote control device is connected
(0V)
G Mains Earth
H,I,J,K Not Used
L Connect pin 4 to pin 8 to instruct machine that a remote control device is connected
(12V DC supply)
M OK to move current detect signal for robotics applications
N OK to move current detect signal for robotics applications
10.3 Positive Terminal ƒ
Welding current flows from the Power Source via heavy duty bayonet type terminal. It is essential,
however, that the male plug is inserted and turned securely to achieve a sound electrical connection.
10.4 Negative Terminal „
Welding current flows from the Power Source via heavy duty bayonet type terminal. It is essential,
however, that the male plug is inserted and turned securely to achieve a sound electrical connection.
CAUTION 1
Loose welding terminal connections can cause overheating and result in the male plug being fused in the
bayonet terminal.
10.5 Gas Outlet …
The Gas Outlet is control by an in-built solenoid valve and is a 5/8 18 UNF female gas fitting.
10.6 ON/OFF Switch †
This switch connects the Mains supply voltage to the inverter when in the ON position. This enables
the user to commence welding
