In the event the pilot arc is not transferred between the plasma torch (electrode) and the work piece
within three seconds of pilot arc start, the cycle automatically stops (pilot arc stops) and the post flow air
continues to run cooling the torch.

CUTTING WITH A HAND TORCH
• The torch can be comfortably held in one hand or steadied with two hands. Choose the
technique that feels most comfortable and allows good control and movement. Position the
index finger or thumb to press the control switch on the torch handle.
• With the torch in starting position, press the trigger. After an initial gas purge (pre-flow), the
pilot arc will come on and remain on for 5 seconds until the cutting arc starts.
• For edge starts, hold the torch perpendicular to the work piece with the front of the tip on the
edge of the work piece at the point where the cut is to start (Fig. A). For piercing, angle the
torch slightly to direct the sparks away from the torch until the pierce is complete (Fig. B).
• For drag cuts keep the torch in contact with the work piece.
• For straight-line cuts, use a straight-edge as guide for your torch.
• For circle cuts, use a template or circle cutting attachment guide to get the radius you desire.
