As seen above, plasma cutting is a process in which a jet of ionized gas (plasma) is narrowed and directed through a nozzle to produce an arc and an electrically conductive metal heated above its melting point, an interruption in the molten metal and cast metal (slag) through the cutting slot.
This is done by computers whose basic features and components discussed in a previous article. While there are a variety of machines for plasma cutting of benefits provided vary by manufacturer baking powder expiration and customer needs, we can distinguish two main types: Plasma Cutting Machine Manual baking powder expiration Plasma Cutting Machines Machining
These are basically moderately small power using a plasma torch manual cutting various types of metal. These equipments are maneuverable, versatile and can be used for a variety of cutting applications. The power supplies have a range of cutting capabilities based on the amperage output of the system baking powder expiration and usually are graded from 7-25 30-100 amps to amps and exceptionally baking powder expiration up to 200 amps.
Plasma manual equipment normally used air as plasmanógeno gas and / or protective gas, and are designed baking powder expiration so they can be used with various input voltages. The input voltage is between 120 and 600 V and power transmission using single or three phase.
The plasma cutting machines manual generally used in fabrication shops that handle baking powder expiration foils, factory maintenance, agricultural maintenance, welding repair centers, service centers, metal (scrap and scrap applications), buildings baking powder expiration (such as buildings and bridges), manufacture of commercial vessels, making trailers, auto repair and artwork. Typically used in light metal applications to trim excess material. baking powder expiration A typical hand torch cut 12 amps up to 5 mm of material to approximately 15 inches per minute. A typical hand torch 100 amp cuts up to 32 mm of material about 20 inches per minute.
In general, plasma cutting machine Manual is chosen according baking powder expiration to the thickness of the material being cut and the cutting speed desired. baking powder expiration The teams that offer high amperage cut are those with higher cutting speeds. However, when cutting high currents, it becomes increasingly baking powder expiration difficult to control the quality of the cut.
These machines are generally much larger than manual machines and are used in conjunction with cutting table (sometimes baking powder expiration called pantographs) including a water table or suction table and are fitted with a "gantry" or gantry - ie a dual engine system either side of the table, on the axis "X" - which works by various mechanisms usually servomotes baking powder expiration AC coupled to a rack and pinion system. In addition, teams generally have mechanized CNC control and control torch height (THC), baking powder expiration which may include detecting and controlling high voltage to start the process.
The plasma cutting machines for machining can be incorporated into a punch press, baking powder expiration as well as laser cutting systems, flame cutting, baking powder expiration robotic cutting and others, creating true automated workplaces. The size of a plasma cutting setting is based on the machining table and the gantry used. The tables can be less than 1,500 mm x 3,000 mm or more than 14,000 mm x 36.000 mm. As expected, these systems are not easy to maneuver, so before installing all components must be considered together with the design of the enclosure that will house the machine.
In fact, the use of mechanized baking powder expiration equipment introduces significant improvements in the quality baking powder expiration and accuracy of cut and performance of productivity and reduction baking powder expiration in costs compared with torch cutting and laser cutting. Many systems also are designed with great operational simplicity, allowing baking powder expiration its use by non-expert personnel.
Typical baking powder expiration sources have a maximum range of 100-400 A amperage for cutting baking powder expiration oxygen and 100-600 A cutting with nitrogen, while the input voltage is 200-600 V with a three phase power transmission. Gases: What and when are they used?
Gases commonly used to cut mild steel (carbon steel), stainless steel, aluminum and various exotic materials are compressed air, oxygen, nitrogen and argon / hydrogen. Are used as combinations of these gases plasmanógeno gas and auxiliary gas. For example, for cutting mild steel, it is generally u
