What is air carbon arc gouging?
What is air carbon arc gouging?
Air carbon arc cutting, also referred to as metal arc gouging, and previously as air arc cutting, is an arc cutting process where metal is cut and melted by the heat of a carbon arc. It employs a consumable carbon or graphite electrode to melt the material, which is then blown away by an air jet.
How much air do you need to arc gouge?
A minimum extension of 2″ should be used to prevent damage to the torch parts. Normal compressed air pressures for CAC-A range between 80 psi and 100 psi at the torch; higher pressures may be used, but they don’t remove metal more efficiently. Use 60 psi (413.7 kPa) with the light-duty manual torch.
What is gouge welding?
Gouging is the term to define a type of corrosion which occurs on a metallic surface in which a hole, groove or indentation is created. In welding, gouging has been a requirement for many years in several industries and applications – and is one method to scrutinise.
How do you cut out old welds?
Usually, you can undo welding using torch cutting, plasma cutting, drills, grinding or circular saws, or oxy-acetylene torches. There are a couple of ways to perform this other than just applying a strong force to the weld.
What are carbon arc rods used for?
The purpose of arc welding is to form a bond between separate metals. In carbon-arc welding a carbon electrode is used to produce an electric arc between the electrode and the materials being bonded. This arc produces temperatures in excess of 3,000 °C.
Air carbon-arc gouging (CAC-A) is the process of cutting/removing metal through intense heat generated from a carbon arc.
How to use gouging rods?
Insert the rods into the handles. Drill for a locking screw on each handle. This screw fixes the rods so they cannot shift or rotate from your setting of their angle. Now place the spring into the countersink holes on the inner surfaces of the handles.
What is carbon arc?
carbon arc. an electric arc between two carbon electrodes, used mainly for lighting, as in an arc light for a motion-picture projector, or for intense heating, as in the cutting and welding of metals.
What are carbon arc rods?
Carbon rods made for carbon arcs are available at some welding supply stores. These carbon rods often have a copper jacket to improve conductivity. The copper melts away from the tips of the carbon rods, exposing a short portion of the carbon rod. Do not connect an arc directly to a power source.
