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 formation, but yields additional penetration and enhanced weld strength. This
agitation is available for all welds with 231 Ws of energy or less.
•
Sustained:
The Sustained agitation option offers high levels of agitation for improved weld
spot strength in some metals. The high levels of agitation energy will affect the spot size
because of the extra energy used in this option. To compensate for this addition of agitation
energy, you may need to slightly lower the overall weld energy when using this option. This
agitation is available for all welds with 132 Ws of energy or less.
Power/ Energy Slider
Use the Power/Energy Slider to adjust the amount of weld energy or weld power that will be discharged depend-
ing on the waveform selected.
• You can touch or drag the slider to adjust the value.
• Pressing on the keypad icon will bring up a keypad for entering exact values. On the keypad, type in the
desired value and press enter. The value on the slider will change and the keypad will disappear.
• As the setting increases it will lead to more forceful welds, more heat at the weld site, deeper penetra-
tion, and larger spot sizes.
•
It can be helpful to start at lower values and gradually increase to higher values to fine tune the weld
results without damaging the workpiece.
Length Slider
Use the Length Slider to adjust the duration of time for each weld energy discharge.
