6. Attach the work clamp securely to the workpiece. Do not attach it to the portion that will fall
away.

7. The Powermax900 is now ready to operate. When you are ready to cut, place the tip of the
torch at the edge of the workpiece. Pull the trigger to start the arc. See
PAC125T Safety
Trigger Operation
later in this section for proper operation of the safety trigger.
8. Move the torch slowly across the workpiece. The arc will transfer from the torch to the work-
piece. Move the torch in the desired direction, at a speed which will ensure good cut quality.
See
Cutting
instructions and the
Cut Chart
later in this section.
9. When the cut is finished, release the trigger to extinguish the arc. The arc will also extinguish
when transfer to the workpiece is no longer sensed.
10. The torch will continue to release gas after the arc is extinguished. This gas postflow will con-
tinue for approximately 15 seconds but can be halted by quickly depressing and then releasing
the trigger. To reinitiate the arc while in postflow, press and hold the trigger.
Pilot Arc Controller Option
In power supplies with the pilot arc controller option, the torch will return to a pilot arc after finishing a
cut if the torch switch remains pressed. After a short delay, the pilot arc will then extinguish if no arc
transfer is sensed. The pilot arc controller option is especially useful if you are cutting expanded metal.
See
Powermax900 Field Upgrade Kits and Optional Parts
in Section 5 for part number information.
WARNING
The PAC125 torches are instant-on torches. These torches produce a plasma arc
immediately after the torch start switch closes. Always hold the hand torch away
from your body as a precaution against accidental torch firing. Be aware of this
hazardous potential. Failure to do so can result in serious bodily injury.
