No point in buying a compressor without CFM info, kind of like buying a welder without knowing the maximum amp output. Assuming you have a service truck, you would want a gasoline powered compressor. If you have a big tank, your compressor can catch up when you set down the tool, so you can live with a little less cfm.
“You can’t afford to take shortcuts with equipment repair. If you take a shortcut, the equipment can bust apart and potentially hurt someone,” says Isaac Carrion, owner of Welding Repair Services, Austin, Texas. The hard, rocky ground around Austin really beats up equipment, and Carrion uses three key cutting tools to keep equipment running: Victor® oxy-fuel cutting torches, an Arcair® air carbon-arc gouging system and an Arcair SLICE exothermic cutting system. Carrion used these same two cutting tools to repair an excavator boom that failed.
Miller Electric pumped up the power of its Big Blue Air Pak welder/generator/air compressor combo, replacing a 40-hp Deutz used in previous Air Paks with a 65-hp Deutz 2011. Former models used one of the engine’s cylinders as an air compressor, but the new Air Pak has Ingersoll Rand’s CE55 G1, rotary-screw compressor under the hood. The belt-driven compressor pumps 35 cubic feet of air per minute compressed to 100 psi.
Air carbon arc cutting is an arc cutting process in which metals to be cut are melted by the heat of a carbon arc. Air carbon arc cutting and metal removal differ from plasma arc cutting in that they employ an open arc, which is independent of the gas jet. The normal safety precautions associated with carbon arc welding and shielded metal arc welding apply to air carbon arc cutting and gouging.
best air compressor for arc gouging Related Question:
How many CFM do I need for arc gouging?
The torch & cable requires a compressor with a recommended output of at least 80 PSI at 22 CFM. “An Arcair air carbon-arc gouging set up was one of the first tools that I purchased when I started out on my own because you can’t fix or repair anything any other way…to last, at least,” says Carrion.
How much psi do I need for gouging?
Position the electrode When using copper-coated carbon electrodes, position the electrode in the torch so that the uncoated end points toward the workpiece. Set the air pressure to 80 to 100 psi, which is a flow sufficient enough to prevent trapping carbon in the gouge.
What equipment is needed for arc carbon gouging?
Required equipment includes an air compressor, welding power source, carbon electrode and a gouging torch. The air carbon arc process is shown in figure 10-75.
What DC current is recommended for use with air carbon arc cutting?
The open-circuit voltage should be higher than the required arc voltage to allow for a voltage drop in the circuit. The arc voltage used in air carbon-arc gouging and cutting ranges from a low of 35V (volts) to a high of 56V; thus, the open-circuit voltage should be at least 60V.
What is the compressed air used for in air carbon arc cutting?
How Does Air Carbon Arc Cutting Work? In this process, an intense arc is used to form a molten pool on a metal workpiece, and compressed air is used for blowing the molten metal thoroughly from the metal surface. It is important that the metal is only gouged or cut along the airflow direction.
What is air carbon arc gouging?
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.
What polarity does carbon steel need?
DC positive polarity allows for a high level of penetration into the steel, while DC negative polarity means less penetration but a higher deposition rate (used on thin sheet metal, for instance).
Can you arc gouge without air?
ZENA NO-Gas arc cutting/gouging rods let you gouge, bevel, and cut metal without needing a 300+ Amp air-arc gouging/cutting rig or an acetylene cutting torch and bulky gas bottles.
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.
Which polarity is suggested use with shielded metal arc cutting?
Electrode-negative (straight polarity) welding results in faster melt-off of the electrode, and therefore a faster deposition rate. Deposition rate refers to the amount of filler metal melted into the weld joint. DC welding offers many benefits, making it a popular choice in shielded metal arc welding (SMAW).
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.
What is the process of carbon arc cutting primarily used in gouging?
Air carbon arc cutting is an arc cutting process in which metals to be cut are melted by the heat of a carbon arc and the molten metal is removed by a blast of air. The process is widely used for back gouging, preparing joints, and removing defective metal.
Can you air arc gouge Aluminium?
This process is useful for cutting a variety of materials, but it is most often used for cutting and gouging aluminum, copper, iron, magnesium, and carbon and stainless steel. Because the metal is blown away by the air jet, it does not need to be oxidized.
Can aluminum be arc gouged?
However, in gouging, specially designed consumables produce a somewhat wider arc, the torch is held at an angle, and only some of the material is blown away. Plasma gouging works on any conductive metal, including mild steel, stainless steel, aluminum, and copper.
What type of electrode is used for CAC A?
The electrodes are rods made from a mixture of graphite and carbon, and most are coated with a layer of copper to increase their current-carrying capacity.
