OPERATION
Manual 0-5300
3. Set Gas Pressures
a. Place RUN/SET switch in SET mode.
b. Adjust plasma and shield pressure regulators to correct pressure or correct flow if using H
2
O Mist option.
(refer to cut chart manual for required pressure/flow.)
c. Return RUN/SET switch to RUN mode. Attempting to START while in the SET mode will cause fault
L303, normally indicating low gas pressure but in Auto-Cut XT units also indicates trying to START while
in SET.
4. Set cutting current.
a. Adjust the Current Control knob to the required output current on the 4 digit display.
5. Prepare to cut.
a. Protect your eyes and ears.
b. Position the Torch to the proper transfer distance above the work piece.
6. Apply START.
• Gas indicator lights; Gas pre-flow starts.
• During gas pre-flow power supply is enabled. DC lamp turns ON.
7. Pilot Arc
• At the end of pre-flow, ignition occurs (arcstarter fires) and the Pilot Arc is established.
8. Transfer
• Almost immediately, if the torch is positioned correctly, the pilot arc transfers to the work and becomes a
cutting (transferred) arc.
• Current quickly ramps up to the level set by the Current Control and the arc pierces through the metal.
• OK to Move signal becomes active and the torch is moved to perform the cut.
9. End of Cut
• START signal is removed; current ramps down and the arc goes out.
• Gases continue to flow for the selected Post-flow time then stops.
• Pump will run for 4 minutes then shut off. Fan will remain on as long as power is on.
10. To make another cut repeat steps 5-9. A second cut can be started anytime after completing the first cut.
11. Shut off the system.
a. Set the ON/OFF power switch on the front panel of the unit to OFF.
WARNING
AC power is still present inside the unit.
• Fans and pump as well as all indicators turn off.
• The display may show a fault code for a moment, this is a normal part of shutting off power and does not
indicate a fault.
b. Open (turn off) the main power disconnect. All power is now removed from the unit.
• Rear panel AC indicator turns OFF.
