being discharged than is possible with Classic .
•
Square - Similar to the triangle waveform, a square waveform allows users to utilize the full amount of
energy over a longer period of time . The difference of this waveform compared to Classic and Triangle is
the abruptness of power at the start and end of each weld . The square waveform closely mimics the weld
output of a typical laser welder .
IgnItIon
The ignition options control the timing of released energy in relation to the position of the electrode .
•
Standard - In the Standard ignition option, the energy discharge occurs at approximately the same time
as the tip lifts off the work-piece surface . This 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 ignition mode is typically used for welding very fine applications that would be damaged
by high energy levels since there is no pre-ignition arc .
•
S - In S ignition mode, the energy discharge occurs well after the electrode tip lifts off the
work-piece surface . While similar to the Standard option, S includes a “pre-heat” function know as
a Focus Arc before the main weld . As the electrode begins to pull away from the surface, a small amount of
energy is discharged prior to the main weld discharge . This additional energy helps preheat the weld area
and helps establish an arc when the electrode is further away from the surface . The S ignition helps
provide better weld consistency by allowing more variation in contact pressure before the weld takes place .
•
Adaptive - In adaptive ignition mode, the arc can be maintained for longer periods of time in order to adapt
to variations in work-piece positioning techniques from user to user . This mode is more forgiving of move-
ment of the work-piece during arc formation . Initially, however, more energy is released into the work-
piece than in the other modes and can be detrimental for smaller weld applications or heat sensitive metals .
It is recommended to perform a few welds on a test piece, to allow this mode to adapt, before performing
actual welds on a work-piece . Welds on a test piece will need to be done every time the unit is powered
down .
agItatIon
During the weld, a high frequency agitation feature can be used to improve weld formation and strength in certain
applications . Positive agitation is added energy to the weld in the form of micro energy bursts . Negative agitation is
subtracted energy from the weld in the form of micro energy pockets . These energy bursts occur at a rate of up to 10,000
times per second . Using agitation can produce an audible, high-pitched “ping” noise . Additional Agitation settings can be
found in the Settings Screen or using the Mini Screen .
None - With “None” selected, no agitation is added to the weld . This is the standard weld discharge curve with a
smooth slope .
Negative – Negative agitation decreases the overall energy of the weld and has the same peak voltage of the weld
without agitation . This can be useful to minimize porosity of the weld .
Sloped - The Sloped agitation option offers low levels of agitation . It has minimal impact on spot size forma-
tion, but yields additional penetration and enhanced weld strength . This agitation is available up to 233Ws of en-
ergy .
