Most typical materials are cut using a plasma cutter including stainless steel, aluminum, copper, brass and nickel.
Plasma cutting is used most often in:
- automotive repair and maintenance
- industrial maintenance and construction
- automotive salvage and scrap-setting operations
The plasma cutter cuts through many layers of different metals using an electrical charge to heat the metal to a critical temperature and then cut it. The plasma stream is emitted from a plasma cutting device and can be shaped as it goes by simply focusing ahead of the cutter and angling the tool head up or down. Multiple passes of the cutting temperature are combined to achieve the level of detail in plasma-cut designs.
Feeding the Base Material:
A common practice in the plasma cutting process involves feeding the base material (the part that is to be cut) into the cutter. A tungsten electrode is then fed through the feed wire to serve as a cutting torch, while simultaneously feeding in the required coolant gas. This allows the plasma cutting process to maintain a steady flow of gases, which keep the plasma cutter at a safe working temperature.
One of the most important things to consider in a plasma cutter is the shielding of the welding surface in front of the torch, you can see the best welding machine price in UAE. It is also best to work in areas that allow easy ventilation of the gases used for welding, as both oxygen and carbon dioxide are harmful to welders.
Why Shielding is Important:
Shielding is one of the key elements in a successful welding operation. When welding a metal, especially one with high power levels, the chances of stray volts getting through to the welder is very high, you can view the price of plasma cutting machine online. The presence of stray voltage, or “hot” voltage, can greatly reduce the performance of the welder and affect the quality of the finished weld. When a welder is shielding, it maintains the safety of the welder by switching off the unnecessary high-voltage circuits, as well as allowing only the necessary current to go through.
Shielding is also an essential component of the plasma cutting process. An example of this is carbon steel studded into the steel of the plasma cutter. Although the stud is there to serve as a filler, a direct connection to the welding project would be undesirable. To solve this problem, a small piece of thin sheet metal is attached across the stud from the welding point.
