MMA Mode

After connecting the welding leads as detailed you will need to switch the power switch on the back panel
to "ON"
Select MMA by switching to the MMA welding mode. There is voltage output at both output terminals.
Set the amperage on the machine suitable for the electrode being used. Ensure you check that you have
the electrode polarity correct. Please see below a guide to amperages required.
