Today, hobbyists and full-time machinists alike frequently depend upon well-constructed plasma cutters to expedite welding and metal cutting projects. The Primeweld.com website offers a great selection of plasma cutters conveniently online. Customers visit this site to obtain these products (and supplies) at appealing prices. This section offers a brief introduction to this exciting technology:
Growing Interest in Plasma Cutting Shop Machinery
During the 1960s and 1970s, a plasma cutting machine remained largely confined to use in high scale production environments. Machinists rely upon these tools to cut and shape metal (especially sheet metal) in desired ways. Plasma cutter technology developed rapidly during the 1980s and 1990s.
Today, prices have fallen considerably for this type of useful shop equipment. A growing number of home workshops include this tool. It proves especially helpful for anyone who anticipates cutting steel, stainless steel, brass, or copper frequently. With care, some welders cut aluminum and painted metals with this equipment, as well.
The Plasma Cutting Process
Welders utilize a plasma cutting machine in either a handheld or a stationary mode. For example, in many factories, this tool remains permanently affixed to a work station. Handheld models permit greater mobility and allow cutting to occur in hard-to-reach locations. However, portable models do require particularly close operator attention during use to prevent accidental power cord entanglement.
During plasma cutting, an electric spark causes an electrode on a plasma torch within a plasma cutter to direct a steady flow of ionized metal onto a metal workpiece, forming an electric cutting arc. Some machines utilize a high voltage circuit to help deliver this initial spark. Others commence operation as soon as the torch touches the workpiece to establish the electric circuit. The latter type of machine supplies continuous cutting capabilities.
Plasma ionization occurs at extremely high temperatures. The nozzle of the cutting machine typically emits a shielding gas layer: for example, highly compressed shop air, nitrogen or argon. This gaseous layer surrounds the cutting arc.
Operators must wear protective gear while using these power tools. Face shields, gloves, boots, and specially designed eye protection recommended by the Occupational Safety and Health Administration help prevent burns and vision impairments. People using this tool need to observe basic safety protocols in order to avoid potentially serious or even life-threatening injuries.
Match The Cutter to Specific Cutting Goals
Different cutters provide a spectrum of cutting capabilities. The simplest models fall into the category of "conventional plasma" cutting machines. They tend to rely upon compressed shop air as a shielding gas, and they will supply a lower amperage cutting arc than more powerful "precision plasma" cutting machines which utilize argon or nitrogen. The latter category of cutters produces higher amperage cutting arcs.
Customers usually benefit by selecting the cutter best suited for the type of shop metal cutting tasks they anticipate performing with some frequency. For example, many home-based shop workers begin cutting using an inexpensive, basic model. An operator who gains proficiency with this tool may eventually decide to upgrade to a more powerful machine to perform precision cutting tasks using higher amperage equipment.
