e following parameters can be set on the Orion 250i2 EV CNC:
MODE
e Orion 250i2 EV CNC can discharge energy following three different “Modes.”
• Triangle mode is used for the majority of the applications. e initial peak voltage is high and tapers
off in a straight, angled line.
• Square mode has lower peak voltages than the triangle mode, but can sustain the peak voltage for
the duration of the energy discharge. is mode can be useful for “delicate” workpiece welding or
for “splashy” metals such as silver or aluminum that become very liquid in the molten state.
• Classic mode mimics the discharge curve of typical capacitive discharge arc welds. e peak voltage
is high initially, but discharges in a parabolic curve which will drop off faster than in Triangle mode.
Classic mode can be useful when the amount of overall heat in the weld needs to be limited.
POWER
e Power setting, in conjunction with Length, controls how much energy will be released as the weld is
discharged.
• e higher the power, the more heat will be put into the weld. is typically leads to larger weld
spots with more penetration.
• A general rule of thumb is the depth of penetration equals approximately 1/3 the diameter of spot
size.
• When selecting power settings, it is a good idea to start low and increase incrementally until results
are achieved.
• Some of the more conductive metals like copper or silver will require higher power settings than
other metals.
LENGTH
e weld length setting dictates how long the discharge of energy lasts (in milliseconds).
• For most applications, the length can be set at the maximum for smooth weld puddles and good
penetration.
• Decreasing the length will lower the overall amount of energy entering the weld spot, which leads to
decreased heat into the weld area.
• In Triangle and Classic modes, decreasing the length can sometimes cause the welds to seem
“punchy” since the voltage is cut off closer to the peak (not allowing the lower voltages to “smooth”
