.
Typically from 1 to 10 PPS. Provides a heating
and cooling effect on the weld puddle and can
reduce distortion by lowering the average
amperage. This heating and cooling effect also
produces a distinct ripple pattern in the weld
bead. The relationship between pulse frequency
and travel speed determines the distance
between the ripples. Slow pulsing can also be
coordinated with filler metal addition and
increase overall control of the weld puddle
In excess of 40 PPS, Pulsed TIG becomes more
audible than visible-causing increased puddle
agitation for a better as-welded microstructure.
Pulsing the weld current at high speeds-between
a high Peak and a low Background amperage-
can also constrict and focus the arc.This results
in maximum arc stability, increased penetration
and increased travel speeds(Common Range:
100-500 PPS).
The Arc-Sharpening effects of high speed
pulsing are expanded to new dimensions. The
ability to pulse at 5,000PPS further enhances
arc stability and concentration potential-which
is extre mely beneficial to automation where
maximum travel tspeeds are required.
3. Trigger Mode Control Button (HF TIG and LIFT TIG Mode only)
The trigger mode control is used to switch the functionality of the torch trigger between
2T and 4T.

Press and hold the torch trigger to activate the power source (weld). Release the torch
trigger switch to cease welding.
