PLASMA CUTTING AND GOUGING

Cutting technique

Place the torch in position for cutting or gouging. For most cutting operations the contact cutting shield should be used. It is placed directly on the work piece at the edge where cutting should start.

Lift the trigger protection and press the triggerswitch on the torch handle. Air will flow for one second before the pilot arc strikes.

The pilot arc will burn for about 3 seconds. If contact with the work piece is not obtained within this time, the pilot arc goes out. Reposition the torch to ensure that the pilot arc will reach the work-piece and make a new try.

When the cutting arc is established, pull the torch slowly across the surface that is to be cut. At correct speed the sparks goes straight through the metal with only a slight bending towards the beginning of the cut.

Pause briefly at the end of cut before releasing the trigger.

The plasma arc goes out immediately. Air will continue to flow for about 30 seconds. When removing the finger from the trigger, the trigger protection will close over the button.
