Plasma Arc Machining Equipment

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasmatypical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as wellplasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts.

Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw.

Plasma arc machining equipment. In this part of the series the process fundamentals are described with emphasis being placed on the operating features and the advantages of the many process variants. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. That means we get the plasma state that we wanted for plasma arc machining. The plasma arc process has always been seen as an alternative to the oxy fuel process. The plasma cutter is not only a useful equipment but also a possibly risky tool if proper safety measurements arent taken while working with it. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. We sell a wide variety of plasma machines manufactured by hypertherm miller thermal dynamics and esab. Today we will learn about plasma arc welding principle types working equipments application advantages and disadvantages with its diagram. This article throws light upon the three main equipments required for plasma arc cutting pac of metals. Plasma arc welding is a liquid state welding process in which the metal to metal joint forms in molten state. We also carry plasma torches and plasma consumables. Pac can cut any electrically conductive metal if its thickness and shape permit full penetration by plasma jet. The term plasma as employed in physics means ionized particles. The plasma arc cutting process cuts metal by melting a section of metal with a constricted arc. As the gas comes in contact with the plasma there is a collision between the atoms of a gas and electrons of an electric arc and as a result we get an ionised gas.

The electric arc is formed between an electrode which is usually but not always made of sintered tungsten and the workpiecethe key difference from gtaw is that in paw by positioning the electrode within the body of the torch the plasma arc can be separated from the shielding gas envelope. Power sources for pac are designed with ocv open circuit voltage in the range of 120 to 400 volts constant. The basic arrangement for a plasma arc cutting torch similar to the plasma arc welding torch is shown in figure 10 71. This article is all about plasma cutter personal protective equipment. Hence the plasma cutting safety issue is now a great concern while working with this tool. Plasma arc cutting pac is ideal for many industrial applications. The plasma arc cutting process is illustrated in fig. A high velocity jet flow of hot ionized gas melts the metal and then removes the molten material to form a kerf. The hot ionized gases are known as plasma.
