MMA (SMAW) WELDING MODE
INSTALLATION AND GUIDANCE
• Plug the cables, electrode holder and earth clamp into the plug connections.
• Respect the electrical polarities and the strength of the welding power indicated on the electrode boxes.
• Remove the coated electrode from the electrode holder when the welding power source is not in use.
• The equipment is fitted with 3 inverter-specific features:
- Hot Start provides an overcurrent at the beginning of the welding process.
- Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool.
- The Anti-Stick technology makes it easier to unstick the electrode from the metal.
MMA WELDING PROCESSES
• Standard
This welding method is suitable for most applications. It is suitable for welding
with all types of coated, rutile, basic and cellulosic electrodes and on all mate-
rials: steel, stainless steel and cast iron.
Recommendations:
- Use low Hot Start for thin sheets, and high Hot Start for thicker sheets and diffi-
cult metals (dirty or oxidised parts).
- The Arc Force can be adjusted from -10 to +10 It should be considered in
conjunction with the choice of electrode type selected in the Advanced Menu
(see Advanced Menu).

• Pulse
This welding mode is recommended for applications in a vertical upright position
(PF). Pulsing keeps the weld pool colder while still promoting material transfer.
Without pulsing, vertical rising welds require a «fir tree» movement, i.e. a challen-
ging triangular movement. With MMA Pulse, this movement is not necessary, and
depending on the thickness of your workpiece, a straight upward movement may
be sufficient. However, if you want to enlarge your weld pool, a simple sideways
movement similar to flat welding will be adequate. If this is the case, you can set
the frequency of your pulse current on the display. This process offers greater
control of vertical welding tasks.
Recommendations:
- Use low Hot Start for thin sheets, and high Hot Start for thicker sheets and diffi-
cult metals (dirty or oxidised parts).
- The Arc Force can be adjusted from -10 to +10 This should be considered in
combination with the electrode type selected in the Advanced Menu (see below).
