On the bottom of the Plasma System there is a plate that includes all of the operating specifications of
your Forney 250P+ Plasma System. Including the serial number of the product.
The duty cycle is the amount of time, in minutes, that a plasma arc can remain on within a 10-minute
period when operated at an ambient temperature of 104 degrees F (40 degrees C).
• At 12 A, the arc can remain on for 2.5 minutes out of 10 minutes without causing the unit to
overheat (25% duty-cycle).
If the power supply overheats because its duty cycle is exceeded, the yellow temperature LED will
illuminate, the arc will shut off and the cooling fan will continue to run. To resume cutting, wait for the
yellow temperature LED to extinguish.
NOTE:
Exceeding duty cycle can damage the system and void
warranty
