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
Loose welding terminal connections can cause overheating and result in the male plug being fused in the
bayonet terminal and /or melting of the housing (case).

Remote Control Socket
The 19 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.
