Lift-ArctTIG - 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.
