5.3 Function explanations for settings
DC, Direct current
A higher current produces a wider weld pool, with better penetration into the
workpiece.
The current is set in the measure screen, weld data setting or fast mode menus.
Arc force
The arc force is important in determining how the current changes in response
to a change in the arc length. A lower value gives a calmer arc with less spatter.
The arc force is set in the weld data setting menu when the synergy function is deactivated.
Min. current factor
The setting of min. current factor is employed when using certain specific electrodes.
The setting should not be altered.
Regulator type
Affects the short circuit process and heat in the weld.
The setting should not be altered.
Synergy
Synergy for MMA welding means that the power source automatically optimises the
properties for the electrode type and dimension that have been selected.
Synergy for MMA welding is activated in the weld data setting menu.
Hot start
Hot start increases the weld current for an adjustable time at the start of
welding, thus reducing the risk of poor fusion at the beginning of the joint.
Hot start for MMA is activated in the weld data setting menu.
Setting limits and measure limits
In limits, a limit number is selected. For settings, see the “Edit setting limits” and “Edit
measure limits” sections in the "TOOLS" chapter.
Limits are activated in the weld data setting menu.
