6. Sharpening thread
You can set 3 parameters:
Sharpening thread
Stuck wire test: Test if the wire is stuck in the weld pool at the end of welding
Automatic unsticking: if the test indicates that the wire is stuck, a power impulsion will automatically burn back the wire, and then will
check it.

The crater fill phase allows filling up of the crater at the end of the weld for a good finish of
welding. It is made by decreasing the arc regime at the end of the weld (downslope), then
maintaining a low level of the wire speed for a defined timing (Craterfiller step).
Remark :
With the SYN mode, the wire speed of the Crater fill step is tuned relatively to the wire speed of
the welding step (∆ [-70 %]), the real speed is shown for information in grey tint, and is directly
tunable with the MAN mode: wire speed (m/min) [1.0 ; 25.0].
You can activate the option Shorten down slope control in the menu:
Configuration > Installation > Cycle.
: The Post Retract Spray allows ejecting the drop at the end of the wire after the welding
Timing of gas output after the end of welding in order to prevent oxidation while the bead is still
hot.
Step time : T(s) [0.05 ; 10.00]
downslope : T(s) [0.05 ; 10.00]
