8. Negative Welding Output Terminal
The negative welding terminal is used to connect the welding output of the power source to the
appropriate welding accessory such as the MIG torch (via the MIG torch polarity lead), TIG torch or
work lead. Negative welding current flows to the power source via this heavy duty Dinsetype terminal.
It is essential, however, that the male plug is inserted and turned securely to achieve a sound electrical
connection.
Loose welding terminal connections can cause overheating and result in the male plug being
fused in the Dinseterminal.
9. Remote Control Socket
The 8 pin Remote Control Socket is used to connect remote control devices to the welding power
source. To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.
