Plasma Cutting

  1. Getting the Most Out of Your Plasma Cutter

    Check out these winning tricks of the welding trade to improve your technique in plasma cutting:

    Plasma arc cutting is an easy, fast and so handy that quite a few people keep their oxy-fuel setups switched off using it to just preheat their metal. In plasma arc cutting, a gas – which is normally air - combines with the electrical arc and forms a very high temperature plasma arc that runs from the electrode to the task piece (which can be any kind of material that conduct electricity) and carves through the metal.

    When comparing plasma cutting to the mechanical or the oxy-fuel techniques of cutting, it certainly has many advantages. Plasma is much faster than oxy-fuel and cuts quicker – up to 75 ipm on 3/8 in steel. For instance, the Director of Ride Engineering for the Stratosphere Casino in Las Vegas, Patrick Brinckerhoff, carried out his own test for cutting speed before knocking down the high roller coaster on top of the Stratosphere Tower. Where a cut

  2. Welding Processes and their Power Supply

    There are many welding processes that apply power supply and which are presented in this article. One of the most popular welding processes that commercial welders perform these days and which had great usage in the past decades is the arc spot welding. The advantage of this type of welding is the ability of the commercial welder to spot weld from one side of the work. Moreover, this is a very fast welding method for the production of multiple spot welds with a high degree of reproducibility.

    MIG welders know that the arc spot welding can be done by using gas shielded metal arc processes and tungsten inert gas. When the multiprocess welder performs tungsten spot welding, one uses the same power supply that is required when performing regular TIG welding process. In this case however, the commercial welder requires special spot welding gun and controls. During the TIG spot

As a rule, the commercial welder

  4. Basic Cutting Operations in a Typical Fab Shop

    Today fabrication shops need to be versatile and well rounded to do the work that their customers request. Even though the products made vary widely from shop to shop, plant the plant, and state to state, the welding and cutting processes that are used are typical in nature, and widely used across industry.

    The main processes in the fab shop usually focus around cutting and welding operations.

    Cutting is an important operation in the fab shop as it used to break down the raw material into smaller length components or different shaped parts for the product that needs to be built. Cutting can be done with mechanical tools called saws an/or shears.

    Shears usually cut in a straight line and a saw is capable of cutting both straight and/or shapes depending upon the saw type. A saw can have a metal blade with teeth on it or it can use an abrasive type blade. The shear and saw are used to make smaller length or smaller shaped components.

  5. A Study of the Pros and Cons of CNC Plasma Cutter

    A Study of the Pros and Cons of CNC Plasma Cutter

    The plasma cutters are those that are normally utilized for cutting metals and the procedure for cutting have been endorsed in the 70s which has some advantages too. Given below is a list of both the Pros and Cons of the equipment used for CNC plasma cutting.

    The Pros:

    The Speed Factor: It is possible to immediately cut the torch since the hazard of preheating is not required. The speed of the cutter will depend on the parts of the laser cutter equipment that you have.

    Flexibility: A plasma cutter is able to easily cut through metals having a thickness as of even 6 inches. During a procedure, it is able to pierce and even show beveling and cutting.

    It is Accurate: Since the entire software required

  6. What Is Plasma Cutting

    What is plasma cutting/How Does A Plasma Cutter Work?

    Plasma cutting is a process used to cut steel and other metals with various thicknesses with compressed air. Generally known as the Oxy Acetylene killer, the plasma cutting

    Plasma Cutter History

    Process is much cleaner, faster, and a more efficient way to cut metal. The plasma cutting process begins compressed air blown out of the nozzle (a part of the plasma torch) at extremely high speeds, while at the same time an electrical arc is formed through the nozzle via High Frequency or Pilot Arc starting methods through the nozzle to the surface being cut causing the gas to turn to plasma.

    By adding electricity through an electrode (hafnium), the gas becomes imbalanced and conducts electricity. The more electrical energy added, the hotter the plasma arc becomes

    Plasma Cutters have been around for over 50 years. Plasma Cutters were a major part of World War II era. During the
