What are the types of carbon arc gouging electrodes?
There are three types of carbon electrodes: AC coated electrodes (for use with AC power sources), DC plain electrodes and DC copper-coated electrodes.
What do you need for air arc gouging?
3 “Recommended Practices for Air Carbon-Arc Gouging and Cutting.” Like arc welding, CAC-A uses an intense arc to create a molten pool on the workpiece. Compressed air blows away this molten metal. The process requires a welding power source, air compressor, carbon electrode, and gouging torch.
What are carbon arc rods used for?
Carbon arc welding is useful for welding thin high-nickel alloys. With the carbon arc welding, the model metal can be easily welded by using a suitable coated filler rod. Carbon arc welding can be used for welding the galvanised sheets using the copper-silicon-manganese alloy filler rod.
How many CFM do I need for gouging?
12-15 cfm will work but will work the compressor full time. The bigger the compressor and the more tank you have the longer it will last and more efficiently it will work. Most work can be accomplished without opening the air all the way on the torch.
What is a gouging rod?
Gouging carbon rods are used for metal removal at fast rates with low power consumption. It is generally used to remove welding defects, excess welds and foundry risers from cast products. Our carbon gouging rods are precisely machined and manufactured in state of the art facilities.
What are gouging rods made of?
Gouging electrodes are made of carbon and have a copper coating. Gouging carbon rods are used for metal removal at fast rates with low power consumption. It is generally used to remove welding defects, excess welds and foundry risers from cast products.
Can you carbon arc aluminum gouge?
The air carbon arc process is inexpensive and efficient on all suitable metals. It is used for gouging and cutting magnesium, iron, copper, aluminum, and stainless and carbon steels.
Are carbon arcs 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. Molten metal is then removed by a blast of air.
How loud is carbon arc gouging?
Air carbon arc cutting and gouging is a welding process that exposes workers to hazardous sound levels from 108-120 dB(A). Welders who perform the gouging process and other workers in close proximity to the process are at risk for noise-induced hearing loss.
What is carbon arc gouging?
Carbon-arc gouging is a melting operation, where metal is removed from the surface by the arc pressure or force. Direct current (DC) is used and the electrode is graphite coated with a layer of copper to assist conductivity. Most materials may be gouged by the process, but the cut is usually wide and ragged.
Is carbon arc gouging hard on a welder?
Carbon arcing is just plain hard on welding machines. Like I said most welders wouldn’t know the difference in the quality of arcs to start with.
How does air carbon arc gouging work?
Process description. Air carbon arc gouging works as follows. An electric arc is generated between the tip of a carbon electrode and the workpiece. The metal becomes molten and a high velocity air jet streams down the electrode to blow it away, thus leaving a clean groove.
What type of rod is used for arc cutting?
Gouging & Cutting Rods are used in Air Carbon Arc Cutting, also called Metal Arc Gouging. Steel Supply, L.P. stocks these Copper Coated Carbon Gouging & Cutting Rods in various diameters from 1/8″ to 3/8″.
What is the difference between AC and DC arc gouging?
As air carbon arc gouging does not rely on oxidation it can be applied to a wide range of metals. DC (electrode positive) is normally preferred for steel and stainless steel but AC is more effective for cast iron, copper and nickel alloys.
What are the typical operating data for air carbon arc gouging?
Typical operating data for air carbon arc gouging: Electrode diameter (mm) Electrode diameter (mm) Current A Note: DC electrode Gouging dimensions Gouging dimensions Depth (mm) Width (mm) Manual 6.4 275 6-7 9-10 Manual 8.0 350 7-8 10-11 Manual 9.5 425 9-10 12-13
