Standard mode is useful when using the Orion 250i2 EV CNC in Arc Mode (no weld head plugged in)
and welding small wires that can’t withstand the focus arc present in the other modes .
•
S ignition mode should be used for most applications and includes a focusing “pre- arc”
that helps initiate the flow of plasma for the main energy discharge .
•
Tip Saver mode also utilizes a pre-arc, but releases the main energy discharge such that the
electrode is further away from the surface when the energy is released . This can help prevent tip
contamination and degradation . If the system is misfiring on multiple occasions or creating surface
welds only, it may be necessary to revert to the S ignition mode .
ELECTRODE TIMING SETTINGS
EV mode on the Orion 250i2 EV CNC allows users to customize the timing of electrode movement by
pressing the word “Ignition” from the main tab .
MODES
•
Lift-off Delay is in microseconds and is the amount of time between when the tip retracts and when
the weld occurs .
•
Time between welds is in milliseconds and is a delay after a welds occurs and before another weld
can happen .
•
Tip Retract Distance is in millimeters and is the amount of distance between the electrode tip and
the weld surface at the time of discharge . (This allows for less contamination on the electrode tip,
but with smaller energies there will need to be less distance otherwise a weld will not occur) .
•
Head Travel Delay is in milliseconds and is the time it takes the nozzle cone to travel and make
contact with the weld surface, after the delay happens the electrode will then come down and make
contact with the weld surface and weld .
