MMA operation steps
Select the welding current setting function by pressing the welding
parameter selecting key and welding current in MMA can be set.
Welding current setting can be carried out during welding.
Select the arc ignition time setting function (this function also
changes spot welding time when setting function is in TIG spot
welding mode) by pressing the welding parameter selection key the
arc ignition time in MMA can be set. Arc ignition time setting can be
carried out during welding.
Select the arc force current setting function by pressing the welding
parameter selection key, and arc force current in MMA can be set.
The arc force current setting can also be adjusted during welding.
If the secondary cables (welding cable and earth cable) are long, select cable with larger cross-section to
reduce the voltage drop.
Preset the welding current
according to the type and size of
the electrode, clip the electrode
and then welding can be carried
out by short circuit arc ignition.
For welding parameters, please
refer to the opposite table.
