RAZOR CUT 45 PFC OPERATING MANUAL Fire hazard • Welding/cutting on closed containers, such as tanks, drums, or pipes, can cause them to explode. Flying sparks from the welding/cutting arc, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of the electrode to metal objects can cause sparks, explosion, overheating, or fire.

RAZOR CUT 45 PFC OPERATING MANUAL 11. Machine Operation Information Compressed Air Requirements A reliable and consistent supply of clean, dry compressed air is essential for proper operation. Although the machine contains its own internal air supply filtration system, it is recommended the compressed air supply should have external filtration in the line feeding the machine, both a standard water trap (sintered bronze filter) and also a coalescing filter (for oil in the air).

RAZOR CUT 45 PFC OPERATING MANUAL Electrode Condition A fixed gap is established between the electrode and the inside of the cutting tip — electrons arc across the gap, ionising and superheating the air creating the plasma stream. The electrode contains an insert at the end made of a highly conductive material called hafnium.

RAZOR CUT 45 PFC OPERATING MANUAL How a Plasma Cutter Works Plasma cutters work by passing an electric arc through air that is passing through a constricted opening. The electric arc elevates the temperature of the air to the point that it enters a 4th state of matter. We all are familiar with the first three: i.e., solid, liquid, and gas.

RAZOR CUT 45 PFC OPERATING MANUAL Amperage The 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 a lower-amperage tip to maintain a narrow kerf.
