1) 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 dinse type terminals.
It is essential, however, that the male plug is inserted and turned securely to achieve a sound
electrical connection.
2) Connect the work lead to the negative welding terminal (-). If in doubt, consult the electrode
manufacturer. Welding current flows from the power source via dinse type terminals. It is
essential, however, that the male plug is inserted and turned securely to achieve a sound
electrical connection.
3) Select MMA mode with the process selection control, see section 5.4.1 " Firepower MST-200".
WARNING!
Before connecting the work clamp to the workpiece make sure the electricity supply
is switched off.
CAUTION!
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 terminal.
