MMA WELDING OPERATIONS

For coated electrode welding, the machine support functions of priming (Hot-Start), material transfer assistance (Arc-
Force) and prolonged short-circuit power reduction (Anti-Stick).
SOLTER
SOLDADURA S.L.
Obn: Fine adjustment in % of the base current for pulsed transfer. For nominal power
or double pulsed, high level. Default 100%.
Opn: Fine adjustment in % peak amperage for pulsed transfer. For nominal power or
double pulsed, high level. Default 100%.
Otn: Fine adjustment in % of peak time for pulsed transfer. For nominal power or dou-
ble pulsed, high level. Default 100%.
Frd: Double pulsed frequency. A high value allows closer marks in the weld. You can
adjust the frequency between 0.5Hz and 25.0Hz.
Pod: Default 0. Possible values from +10 to -10. Positive values cause greater diffe-
rence between high and low level of double pulsed. In contrast, negative values reduce
the power difference between the two levels.
Obl: Fine adjustment in % of base current for pulsed transfer corresponding to low
level of double pulsed. Default 100%.
Opl: Fine adjustment in % of peak current for pulsed transfer corresponding to low
level of double pulsed. Default 100%.
Otl: Fine adjustment in % of peak time for pulsed transfer corresponding to low level of
double pulsed. Default 100%.
For the MMA mode there are three additional parameters that can be set by
accessing the SET menu.
MMA Hot Start: Start current level for coated electrode arc. The value is re-
ferred to as a percentage of the rated current. A value of 100 to 150% helps
better penetration of the material when starting the bead.
MMA hot-start time: Time during which the hot-start is applied. Can be set
from 0 to 2.5 seconds.
MMA Force-arc: A high value helps prevent the electrode sticking to the
work piece. A high value improves the welding quality of cellulosic type elec-
trodes or aluminium alloys.
Connect the electrode clamp and earth clamp according to
the instructions of the electrode used. Use the terminals on
the front of the power unit.
Select the MMA mode. Having selected the MMA mode,
you can set the desired welding amperage.
