Plasma Cutters

 

Plasma cutting is a process that is used to cut steel and other metals using a plasma cutting torch.  Plasma cutting is an important process for any metal fabrication shop or business. Unlike oxy fuel, plasma can cut stainless steel, aluminum, and brass, as well as mild steel.

Regardless of the size, all plasma cutters function on the same principle and they are constructed primarily around the same design.  Plasma cutters are available in many different sizes.

 

Plasma cutters function by sending a pressurized gas like nitrogen, argon, or oxygen, through a small channel. In the middle of this channel, you will find a negatively charged electrode. When you apply power to the negative electrode, and you touch the tip of the nozzle to the metal, the connection creates a circuit. A powerful spark is then generated between the electrode and the metal and as the inert gas passes through the channel, the spark heats the gas until it reaches the fourth state of matter. This reaction creates a stream of directed plasma that reduces metal to molten slag. The plasma itself conducts an electrical current. The cycle of creating the arc is continuous as long as power is supplied to the electrode and the plasma stays in contact with the metal that is being cut. In order to ensure this contact you must protect the cut from oxidation and regulate the unpredictable nature of plasma.  The cutter nozzle has a second set of channels and these channels release a constant flow of shielding gas around the cutting area. The pressure of this gas flow effectively controls the radius of the plasma beam
