Plasma cutters are capable of cutting metals in simple and complex shapes including producing holes, bevel edges, gouging, and markings. Plasma is a cost effective and practical alternative to oxy-fuel, laser and water jet cutting processes and is used in industrial, trade and DIY applications. Plasma cutters are used in all types of industries including manufacturing, pharmaceutical, oil/gas and arms industries.
When gas is heated to extremely high temperatures, the electrons in the gas molecules break free from the nucleus, turning the gas into plasma. Plasma cutting is carried out by directing the plasma jet through the metal.
The advantages and disadvantages of plasma cutting as compared to the other cutting processes are as follows:
Pre-weld and post-weld heat treating is critical for many welding operations. Without proper thermal manipulation, welds and heat affected zones can have mechanical properties that are undesirable. Worse yet, inadequate heat treatment can result in cracks and devastating weld failures. While temperature and time are the primary concerns when heat treating a weld, the heating method should also be considered diligently when selecting a process. Induction heating is one of the most popular types of heat treating methods, and rightfully so. The benefits of induction heating are many, and Red-D-Arc has the equipment you need to successfully implement an induction heat treating operation for your projects.
What is Induction Heating?
Induction heating is a heat treating process that, when used properly, can alter the mechanical properties of a weld and its adjacent base metal in a way that meets the demands of the application in which the weld is being used. Induction heating relies on the science of electromagnetism to heat the part. Induction coils are placed around the material being heat treated, and alternating current is fed through them. This alternating current going through the induction coils creates a rapidly alternating magnetic field.
The eddy currents that occur as a result of this heat the material surrounded by the coils. Magnetic materials are even more easily heated by the alternating magnetic fields.

This versatile series of pipe saws are capable of cutting, 2 inch through 24 inch pipe and solids made from materials including ductile iron, steel, stainless steel, alloys, structural steel pieces and rails. They provided fast, accurate, square faced cold cuts at right angles and can be mounted in any position. Since they are so versatile, the Guillotine Pipe Saws have been used by water and gas companies, nuclear power, petrochemical operations, refineries, and for regular plant maintenance. E.H. Wachs Guillotine saws are completely portable with a rugged design that stands up under demanding conditions. They are compact and easy to operate and require very little maintenance. Precise fingertip controls allow the operator to adjust the speed of the saw blade for optimal results. These pipe saws are used extensively in nuclear facilities and underwater operations due to their capacity for robotic setup and operation. Installation time is less than three minutes. These pipe cutting saws have been adapted for many unique situations and work well under adverse conditions.
