Plasma Cutting Tips

Always read and follow the safety precautions and operational instructions in your owner's manual.

1. Connect work clamp to a clean, paint free location on the metal workpiece, as close to the cutting area as possible.

2. If your plasma system includes adjustable air, set the air pressure to the factory recommended pressure (psi) for cutting.
 3. For standard (shielded) cutting, place the drag shield on the edge of the metal. For non-shielded cutting, use 1/8 in (3.2mm) standoff distance (dragging a non shielded tip on the metal will reduce tip life)
 4. Raise trigger lock and press the trigger. The pilot arc will start. The pilot arc starts immediately when trigger is pressed
5. Move the pilot arc into the metal being cut.
 6. After the cutting arc starts, slowly start moving the torch across the metal.
 7. Adjust the torch speed so sparks go thru the metal and out the bottom of the cut.
 8. If sparks are being blown upward and back at the torch head, your speed is too excessive.
 9. At the end of the cut, pause briefly before releasing the trigger to sever the work piece.
10. Postflow continues for approximately 15 to 20 seconds after releasing the trigger. The cutting arc can be instantly restarted during postflow by raising the trigger lock and pressing the trigger.
