SAFETY www.bestarc.com HOW A PLASMA CUTTER WORK Basic plasma cu�ers use electricity to superheat air into plasma (the 4th state of ma�er), which is then blown through the metal to be cut. Plasma cu�ers require a compressed air supply and AC power to operate.

SAFETY www.bestarc.com HOW DOES PLASMA CUTTING COMPARE TO OXY-FUEL (GAS) CUTTING? Plasma cu�ng can be performed on any type of conduc�ve metal-mild steel, aluminium and stainless are some examples. With mild steel, operators will experience faster, thicker cuts than with alloys. Oxy-fuel cuts by burning, or oxidizing the metal it is severing.

OPERATION www.bestarc.com START CUTTING Hold the torch ver�cally Pull the trigger to start the Then, Proceed with the and observe the arc it cuts arc, the cu�ng arc will cut. along a straight line. ini�ate when the torch �p is close enough to the work piece.
OPERATION www.bestarc.com Pull the trigger to energize the pilot arc. The cu�ng arc will start when the nuzzle is moved closer to the edge of Place and hold the torch ver�cal at the the workpiece. when the cu�ng arc is edge of the plate.

OPERATION www.bestarc.com SET UP PROCEDURE FOR PLASMA CUTTING MACHINE 1. Connect the AG60 Plasma Torch to the machine. Insert the torch connec�on into the torch. Connec�on receptacle at the front of the machine and screw up hand �ght. Cau�on: Be careful not to bend the pins located inside the torch connector.

OPERATION www.bestarc.com AMPERAGE Standard rule of thumb is the thicker the material the more amperage required. On thick material, set the machine to full output and vary your travel speed. On thinner material, you need to turn down the amperage and change to alower-amperage �p to maintain a narrow kerf.
Page 30
OPERATION www.bestarc.com TORCH TIP HEIGHT &POSITION The distance and pos�on of the plasma torch cu�ng �p has an affect on thequality of the cut and the extent of the bevel of the cut. The easiest way toreduce bevel is by cu�ng at the proper speed and height for the material andamperage that is being cut.
OPERATION www.bestarc.com AIR QUALITY Good air quality is essen�al to quality plasma cu�ng and consumable life span. Compressors take in air at atmospheric pressure and increase the pressure and store it in a tank. Humidity in the air is condensed in the tank and in the airlines producing water, more so in humid environments.
