13. Positive Welding Output Terminal
The positive welding terminal is used to connect the welding output of the power source to the appropriate welding
accessory such as the Fusion MIG Gun (via the MIG Gun polarity lead), electrode holder lead or work lead. Positive
welding current flows from the power source via this 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
Loose welding terminal connections can cause overheating and result in the male plug being fused in the
bayonet terminal.
