1.
Turn the power source on and select the MMA function
with the MIG/MMA selector switch. (MMA IS ARC/STICK)
2. Polarity
Two sockets are available on this welding
machine.
For MMA welding the electrode holder is
shown
to
be connected to the positive socket,
while the
earth lead (work piece) is connected to
the negative
socket, this is known as DC+ polarity.
However
various electrodes require a different
polarity for
optimum results and careful attention
should be paid
to the polarity, refer to the electrode
manufacturers
information for the correct
polarity.
DC+ Electrode connected to
output socket.
DC- Electrode connected to
output socket.
(3)
Set the welding current using the amperage control
dial.
(6)
Hold the electrode slightly above the work
maintaining the arc while travelling at an even speed.
(4)
Place the electrode into the electrode holder and
clamp tight.
(7)
To finish the weld, break the arc by quickly snapping
the electrode away from the work piece.
(5)
Strike the electrode against the work-piece to
create an arc and hold the electrode steady to maintain
the arc.
(8)
Wait for the weld to cool and carefully chip away
the slag to reveal the weld metal below.
