5. 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 MIG Gun (via the MIG Gun polarity lead), electrode holder lead or work lead.
Positive welding current flows from the Power Source via 25mm Dinse style connector. It is essential, however,
that the Dinse adapter and male plug are 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 Dinse connector.
6. MIG Gun Polarity Lead
The polarity lead is used to connect the MIG Gun to the appropriate positive or negative output terminal (allowing
polarity reversal for different welding applications). In general, the polarity lead should be connected in to the
positive welding terminal (+) when using steel, stainless steel or aluminum electrode wire. When using flux
cored (gasless) wire, the polarity lead is generally connected to the negative welding terminal (-). If in doubt,
consult the manufacturer of the electrode wire for the correct polarity. It is essential, however, that the Dinse
adapter and male plug are 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 Dinse connector.
7. 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 Gun (via the MIG Gun polarity lead), TIG Torch or work lead. Negative
welding current flows to the Power Source via 25mm Dinse style connector. It is essential, however, that the
Dinse adapter and male plug are 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 Dinse connector.
8. Remote Control and Spool Gun Socket
The 8 pin socket is used to connect the Fusion MIG Gun, remote control device or spool gun plug to the welding
Power Source. To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.
