TRIANGLE e Triangle waveform is similar to the classic waveform’s ability to make smooth and uniform
weld results. One key advantage of the triangle waveform is the ability to set the peak and the length
independently. Meaning, a weld could have a very high peak and a very short time, or a very low peak with
a very long time, or any other combination of these two parameters. A Triangle waveform’s weld power
will always go to zero. In comparison, adjusting the weld time in Classic Waveform to be shorter does not
guarantee that the weld energy discharges to zero. Instead, the energy is simply cut off and not allowed to
fully discharge.
SQUARE Similar to the triangle waveform, a square waveform allows users to adjust the peak and the
length independently. Again, the user can select Square waveform so that a weld could have a very high
peak and a very short time, or a very low peak with a very long time, or any other combination of these two
parameters. e difference of this waveform compared to Classic and Triangle is the abruptness of power
at the start and end of each weld. e square waveform closely mimics the weld output of a typical laser
welder.
IGNITION
e ignition options control the electrode tips position at the moment the energy is released.
STANDARD In the Standard ignition option, the energy discharge occurs at approximately the same time
as the tip lifts off the work-piece surface. Since the electrode is close to the work-piece when the weld
is formed, it’s easier to get a weld on any surface or angle. is mode provides the most accuracy, but
requires the operator to hold the work-piece steadily below the electrode. is mode is perfect for metal
types that do not require a pre-heat phase during the weld. Because the electrode is closer to the work-
piece, the electrode may dull more quickly.
STANDARD+ In Standard+, the energy discharge happens well after the electrode tip lifts off the work-
piece surface. While similar to the Standard option, Standard+ includes a “pre-heat” function before the
main weld. During this time, a very low amount of energy flows through the electrode and work-piece. is
preheating of the tungsten electrode helps create a more efficient weld area in preparation to the main
weld. e Standard+ ignition helps provide better weld consistency by allowing more variation
in contact pressure before the weld takes place.
