3. Pulse time

5. Background time
6. Slope down
7. Gas post flow time
Slope up
The slope up function means that, when the TIG arc strikes, the current rises slowly
to the set value. This provides `gentler' heating of the electrode, and gives the
welder a chance to position the electrode properly before the set welding current is
reached.
Pulse current
The higher of the two current values in the event of pulsed current.

Time
TIG welding with pulsing.
Pulse time
The time the pulse current is
on
during a pulse period.
Background current
The lower of the two current values in the event of pulsed current.
Background time
Time for background current which, along with the time for pulse current, gives the
pulse period.
Slope down
TIG welding uses “slope down”, by which the current falls 'slowly' over a controlled
time, to avoid craters and/or cracks when a weld is finished.
Gas post-flow
This controls the time during which shielding gas flows after the arc is extinguished.
HF
The HF function strikes the arc by means of a spark from the electrode to the
workpiece as the electrode is brought closer to the workpiece.
