OPERATING INSTRUCTIONS
1. Ensure that the work environment and your clothing meet the safety requirements outlined in
the Safety section. Follow the instructions in the Setup section.
2. Verify that the air supply pressure is set between 70 and 120 psi (4.8 - 8.3 bar).
3. At the rear of the power supply, move the power switch to the ON (I) position. The POWER ON
and READY LEDs should illuminate. The PRESSURE, TORCH CAP and OVER-TEMP LEDs
should remain extinguished.
4. Adjust the pressure regulator to 60 psi (4.1 bar) on the pressure gauge:
•
Set the knob to GAS TEST/SET position.
•
Pull up on the adjustment knob and turn it to adjust the pressure to 60 psi (4.1 bar).
•
Push down the knob to lock it.
5. Adjust the AMPS knob to the desired setting. See
Cut Chart later in this section.
6. Attach work clamp securely to the workpiece. Do not attach it to the portion that will fall
away.
7. The Powermax350 is now ready to operate. When you are ready to cut, place the tip of the
torch on the workpiece. Press the torch switch to start the arc.
8. The arc will transfer from the torch to the workpiece. Move the torch in the desired direction, at
a speed which will ensure good cut quality. See
Cut Chart later in this section.
9. When the cut is finished, release the torch switch. Postflow will continue for approximately 10
seconds. The arc can be instantly restarted during postflow by pressing the torch switch.
WARNING
Before operating this system, read the Safety section of this manual thoroughly!
WARNING
The PAC110 torch is an instant-on torch which

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.
