Lift-Arct TIG - Normal
open-circuit voltage is not present
between the electrode and
workpiece. A solid-state contactor
does not energize until after the
electrode touches the workpiece,
preventing overheating, sticking, or
contaminating the electrode (see
Section 4-4). Make connections
according to Section 3-7.
Stick E XX18 Soft - This setting
provides a lower dig/arc force
setting for smooth weld
perfromance. A stable weld puddle
with little arc “snap” gives excellent
weld bead appearance with
minimal spatter. Make connections
according to Section 3-8.
Stick E XX18 Stiff - This setting
provides a higher dig/arc force that
gives a slightly more fluid weld
puddle, more arc “snap”, and
reduces the potential for electrode
sticking at shorter arc lengths.
Make connections according to
Section 3-8.
Stick E XX10 Soft - This setting
provides lower dig/arc force for
open root vertical up joints or joints
that do not require additional
current for fit up inconsistencies.
Make connections according to
Section 3-8.
Stick E XX10 Stiff - This setting
provides a higher dig/arc force for
open root vertical down joints
where additional current is needed
to compensate for tight joint fit up
without the need to increase overall
welding current. Make connections
according to Section 3-8.
