What are gouging carbons?
Contact Us. 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 …
What type of power source is needed for air carbon arc gouging?
three-phase welding power source
However, any three-phase welding power source of sufficient capacity may be used for air carbon arc gouging. The arc voltage used in air carbon arc gouging and cutting ranges from a low of 35 to a high of 56 volts; thus the open-circuit voltage should be at least 60 volts.
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 is a gouging electrode?
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.
How does carbon arc gouging work?
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 DC current is recommended for use with air carbon arc cutting?
Copper-Coated:
| Electrode Type | Electrode Size | Current |
|---|---|---|
| in. | Min | |
| DC (plain) or AC (copper covered) | 3/16 | 150 |
| 1/4 | 200 | |
| 5/16 | 250 |
Can you arc gouge without air?
Amtec 8 is a grooving, chamfering, cutting and gouging electrode used without air or oxygen. It is a very fast and efficient metal working tool. It can be used on all metals including manganese steel, cast iron, stainless steel, and even aluminum.
How does a gouging rod work?
Air carbon arc gouging is a process of removing metal by means of heat generated from a carbon arc. The process uses a carbon/graphite electrode, compressed air and a standard power source. The intense electric arc used between the tip of a carbon electrode and a metal work piece cuts and melts the work piece.
How many CFM do I need for arc 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.
How many amps does it take to arc gouge?
Gouging Electrodes
| ELECTRODE CURRENT REQUIREMENTS | ||
|---|---|---|
| ELECTRODE | 5/32 | 5/8 |
| MIN. AMPS DC | 90 | 900 |
| MAX. AMPS DC | 150 | 1200 |

What is the difference between air carbon gouging and arc gouging?
Air carbon arc gouging. The main difference between this gouging technique and the others is that a separate air jet is used to eject molten metal from the groove. Air carbon arc gouging works as follows. An electric arc is generated between the tip of a carbon electrode and the workpiece.
What is the difference between different gouging techniques?
The main difference between this gouging technique and the others is that a separate air jet is used to eject molten metal from the groove. Click here to see our latest technical engineering podcasts on YouTube. Air carbon arc gouging works as follows. An electric arc is generated between the tip of a carbon electrode and the workpiece.
What is a BOC carbon carbon?
BOC carbons have been produced for effective, efficient metal removal by the arcair gouging process. They are manufactured for high quality gouging with: a first grade quality carbon / graphite mixture. Length: 305mm.
