INSTALLATION/SETUP

3.14 Setup for STICK (MMA) Welding

A. Connect the Electrode Holder lead to the positive welding terminal (+). If in doubt, consult the electrode
manufacturer. 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.
B. Connect the work lead to the negative welding terminal (-). If in doubt, consult the electrode manufacturer.
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. Select STICK mode with the process selection control (refer to Section 3.08.7 for further information)
Before connecting the work clamp to the work and inserting the electrode in the electrode holder
make sure the mains power supply is switched off.
Remove any packaging material prior to use. Do not block the air vents at the front or rear of the
Welding Power Source.
Loose welding terminal connections can cause overheating and result in the male plug being fused
in the bayonet terminal.
