support to prevent falling or tipping.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in the
terminal.
Remove any packaging material prior to use. Do not block the air vents at the front or rear of the Welding

A. Select MIG mode with the process selection control (refer to Section 3.10.13 for further information).
B. Connect the MIG polarity lead to the negative welding terminal (-). If in doubt, consult the electrode wire manufac-
turer. Welding current flows from the power source via heavy duty bayonet type terminals. It is essential, however,
that the male plug is inserted and turned securely to achieve a sound electrical connection.
C. Connect the work lead to the positive welding terminal (+). If in doubt, consult the electrode wire manufacturer.
