Pulse Period
influences the width of the arc and the
amount of heat input to the weld. If the value of
parameters is lower:
Improves penetration and the microstructure of the
weld.
The arc is narrower, more stable.
Reduces the amount of heat input to the weld.
Reduces
distortions.
Increases
welding
speed.
Note:
Adjust range depend on the power source.

Background Current
- value in percentage of nominal
value welding current. Adjusts the overall heat input into
the weld. Changing the background current changes
the shape of the back bead.
Default
value:
60%.
