4-17. Crater Time Control And Final Current Control
1 Sequence Selection Switch
Place switch in Crater position.
2 Crater Time Control
Use control to reduce current
over a set period of time (0–15
seconds) at the end of the weld
cycle when NOT using a remote
current control.
3 Final Current Control
Final current is the current to
which weld current has sloped
down to (0–100% of current set on
Amperage Adjust control).
Application:
Crater Time should be used while
GTAW welding materials that are
crack sensitive, and/or the opera-
tor wants to eliminate the crater at
the end of the weld.
Note: This applies if the operator
is using an on/off only type control
to start and stop the welding pro-
cess.
