the standard unit “ Hertz. ” Simply, it is
the number of pulses per second that
occur. Pulse frequency controls the arc
constriction and also helps with heat
management.

is the percentage (%) of time that the
pulse stays in the TIG (Peak) pulse Amp
stage of the cycle. Increasing the Pulse

TIG Pulse. The TIG pulse creates two amp
values, a high and a low value that cycle back
and forth between each other while welding.
The upper amperage is called the
“ TIG Pulse
Amps ” (sometimes referred to as “ Peak ” cur-
rent.) The lower amperage is called “ TIG
Pulse Base Amps “ (sometimes called
“ background ” or “ base “ current). This cre-
ates a situation where penetration can be
achieved without overheating the metal, par-
ticularly on metals that are prone to structur-
al deterioration or burn through. In effect
you are creating an average of amps. . This
welder features three adjustable parameters
concerning the TIG pulse:
1. Peak and Base Pulse Amps . Both (Peak)
Pulse Amps and Base pulse amps are in-
dependently set.
When selecting the
Pulse Mode, the welder will bypass the
standard TIG Amps LED and will default
to the Peak Pulse Amps LED instead.
When you adjust the base Amps, you are
actually setting a ratio of Amps. Base
amps are expressed as a percentage of
TIG Pulse (Peak) Amps. So, when you set
base amps, you are only setting it as a
percentage, not the actual Amps. As you
increase Peak Pulse Amperage, the pulse
will maintain the same ratio of Amps you
have selected, raising the base Amps au-
tomatically. To adjust the base Amps to
a desired setting, using an example of
100 Peak Pulse Amps, setting the base
Amps to 50% yield s a 50 Amp value for
the pulse base Amps. The foot pedal will
control both Peak and Base Pulse Amps
together, according to the percent of
base Amps selected on the panel.

quency as it is referred to is measured in
