MMA SET-UP
1. Consult the electrode manufacture's documentation to determine the
correct setting. An electrode may be DCEN, DCEP and/or AC compatible.
2. Turn the power source on (H) and select the MMA function with the
TIG/MMA selector switch (M).
3. Choose AC or DC power with the voltage output type (J). The pre-set
amperage number will appear in the digital display meter (I).
3.1 Set the welding current (R) relevant to the electrode type and size
being used (see Welding Current (Amperage)). This can also be
adjusted while welding.
4. Connection of output cables based on the electrode requirements.
4.1 Connect the dinse connector of the electrode holder cable to the
positive outlet socket (B) for DCEP welding.
4.2 Connect the dinse connector of the
electrode holder cable to the negative
outlet socket (C) for DCEN or AC welding.
4.3 Connect the earth ground cable to the
other polarity outlet socket.
5. Place the electrode into the electrode holder
and clamp tight (Fig. 4).
MMA (ARC) WELDING
1. Strike the electrode on the workpiece to create
the arc and hold the electrode steady to
maintain the arc (Fig. 5)
2. The heat of the arc melts the surface of the
base metal to form a molten pool at the end
of the electrode.
3. The melted electrode metal is transferred
across the arc into the molten pool and
becomes the deposited weld metal.
The deposit is covered and protected by a slag which comes from the
4.
electrode coating.
The arc and the immediate area are enveloped by an atmosphere of
5.
protective gas
