6. Positive Welding Output Terminal
The positive welding terminal is used to connect the welding output of the power source to the 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.
7. Negative Welding Output Terminal
The negative welding terminal is used to connect the welding output of the power source to the TIG
torch or work lead. Negative welding current flows to 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.
