the weld puddle and finalize the discharge) .
•
For very small components, sometimes it is helpful to decrease the length to limit the amount of
energy entering the weld .
AGITATION
Agitation is a secondary high frequency wave form that is superimposed over the main energy discharge
to help increase penetration and strength .
•
There are two pre-set agitation modes - “Sloped” and “Sustained .”
•
Sloped agitation is the more mild of the two presets since the intensity of the discharge decreases
in conjunction with the main energy discharge . It is often highly useful for welding steel and similar
metals, but metals like aluminum and silver are not great candidates for agitation due to the highly
liquid nature in their molten states .
•
Sustained agitation is very forceful and should be used only with larger workpieces that require high
penetration since the overlay discharge remains at the same intensity throughout the duration of
the main discharge . Some metals will exhibit molten metal expulsion from the weld site due to the
force of sustained agitation .
ADDITIONAL SETTINGS
Users can customize the frequency, duty cycle, and intensity of the agitation discharge by pressing the
word “Agitation” on the weld screen to enter a settings screen .
•
Frequency - dictates the number of voltage spikes during the weld discharge . Lower frequency
agitation seems to work well for copper tabs to batteries . Higher frequencies can sometimes
improve the weld quality on metals that tend to crack during the weld .
•
Duty Cycle - dictates the duration of each voltage spike . Higher duty cycles seem to be more
effective in most applications .
•
Intensity (Voltage) - dictates the height of each voltage spike . The higher the voltage, the more
intense the agitation result .
•
It can be helpful to look at the onscreen graphic representation while making changes to the
settings to visualize the effect on the discharge curve . Take note of the resulting welds .
IGNITION TIMING PRESETS
Timing can be important for proper arc formation and weld discharge . The Orion 250i2 EV CNC comes with
four timing presets .
