Jorgenson Machine Tools offers Plasma and Plasma/Oxy-fuel cutting machines. These machines are suitable for manufactures that need to cut metal plates quickly and efficiently, especially thicker plates up to 3 inches.

Both Plasma and Oxy-fuel processes remove metal by heating it but each uses a different process to generate the thermal energy. Choosing the best machine depends on your specific application, the materials being cut and other circumstances.

The Plasma cutting machines delivers good precision and cut qualities. On the other hands, a combination machine which can provide both oxy-fuel and plasma cutting expands your overall capabilities and eliminates the need for two machines, which saves both money and floor space.

The plasma cutters transfer energy from an electrical power source through a plasma cutting torch to the material being cut through by using electrically conductive gases such argon, hydrogen, nitrogen or mixtures, plus air and oxygen. This process uses the thermal energy of the plasma arc to melt the metal and pierce through the work piece. The high pressure gas flows through the kerf removing the molten material from the bottom of the cut.

Because of the intense heat generated by the plasma there is a substantial amount of smoke and fumes from the vaporizing metal in the kerf. Therefore, it is important to have proper ventilation in the area of the plasma cutting table.

Oxy fuel cutting use a combination of fuel gases and oxygen to cut metals. Using a torch as the heat source, the metal is heated until it reaches the temperature at which it will spontaneously ignite. At this point, a stream of oxygen is directed down onto the metal, turning it into a metal oxide.

Acetylene is the fuel most commonly used for Oxy fuel cutting but natural gas, propane, hydrogen, propylene, or liquefied petroleum gas (LPG) could also be used.

Lasers and water-jet machines are alternatives to thermal cutting machines.
