- The gas will immediately turn off. The pressure |
gage may show an increase in pressure after the |
air turns off but this is normal. Do NOT reset the |
pressure while the air is NOT flowing. |
PREPARE TO CUT
• When ready to cut, place the torch near the work, |
make certain all safety precautions have been taken |
and pull the trigger. |

- | The air will flow for a preflow time of 2 seconds |
| and the pilot arc will start. (This is true unless |
| the machine is in postflow, then the preflow time |
| is skipped and the pilot arc will start immediate- |
| ly.) |
- | The pilot arc will run for 3.0 seconds and shut off |
| unless the arc is brought in contact with the work |
When preparing to cut or gouge, position the machine as close to the work as possible. Make sure you have all materials needed to complete the job and have taken all safety precautions. It is important to follow these operating steps each time you use the machine.
•Turn the machine's ON/OFF POWER SWITCH to OFF position.
•Connect the air supply to the machine.
•Turn the main power and the machine power switch on.

quickly to improve parts life. |
- When the arc is brought within 1/4"(6.4mm) from |

will ramp up to the setting on the control panel, |

• Pierce the work piece by slowly lowering the torch |
onto the metal at a 300 angle away from the opera- |
tor. This will blow the dross away from the torch tip. |
Slowly rotate the torch to vertical position as the arc |
becomes deeper. |
