3. Positive Terminal<br />
Welding current flows from the Power Source via heavy duty Dinse type terminal. It is essential, however, that the<br />
male plug is inserted and turned securely to achieve a sound electrical connection.<br />
4. Negative Terminal<br />
Welding current flows from the Power Source via heavy duty Dinse type terminal. It is essential, however, that the<br />
male plug is inserted and turned securely to achieve a sound electrical connection.<br />
CAUTION<br />
Loose welding terminal connections can cause overheating and result in the male plug being fused in the<br />
bayonet terminal and /or melting of the housing (case).<br />
5. Remote Control Socket<br />
The 19 pin Remote Control Socket is used to connect remote current control devices to the welding Power Source.<br />
To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.<br />
Socket Pin Function<br />
