D. Main Cutting Arc
DC power is also used for the main cutting arc. The negative output is connected to the torch electrode through the
torch lead. The positive output is connected to the workpiece via the work cable and to the torch through a pilot
wire.
E. Parts - In - Place (PIP)
The torch leads include a ‘Parts - In - Place’ (PIP) circuit. When the torch shield cup is properly installed, it closes
a switch. The torch will not operate if this switch is open.
