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 equipment is used for arc welding?

The arc welding equipment includes a power source, welding cables, electrode holder, chipping hammer, wire brush, hand screen, protective clothing, etc.

What is arc gouging welding?

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.

What are weld consumables?

Welding is the process of joining metals and thermoplastics by means of coalescence. Flux and filler metals together are known as welding consumables. Stick electrode, flux-cored wires, solid wires, SAW wires and fluxes are some of the welding consumables employed during the welding process.

How many amps do you need to arc gouge?

Gouging Electrodes

ELECTRODE 5/32 3/16
MIN. AMPS DC 90 200
MAX. AMPS DC 150 250

What are the 5 basic types of welding joints?

There are five basic welding joint types commonly used in the industry, according to the AWS:

  • Butt joint.
  • Tee joint.
  • Corner joint.
  • Lap joint.
  • Edge joint.

What is arc cutting?

A process of cutting or removing metal by melting it with the heat produced between an electrode and the metal being cut.

What is considered a consumable item?

Consumables are goods used by individuals and businesses that must be replaced regularly because they wear out or are used up. They can also be defined as the components of an end product that is used up or permanently altered in the process of manufacturing such as semiconductor wafers and basic chemicals.

How much air do you need for arc gouging?

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.

How many CFM is carbon arc gouge?

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 is carbon arc gouging used in welding?

Air carbon-arc gouging removes metal through the intense heat of an arc created between a carbon electrode and the workpiece. The air carbon-arc gouging process does not require oxidation to maintain the cut, so it can gouge or cut metals that the oxyfuel process cannot.

When did air carbon arc gouging first start?

1.02 HISTORY Air carbon-arc gouging began in the 1940s, evolving from the existing carbon-arc cutting process. Myron Stepath, a welding engineer, developed air carbon-arc gouging to remove several hundred feet of flat, cracked, stainless steel weld.

What does arcair stand for in welding category?

Today, Arcair is part of the ESAB family of brands, and the name Arcair is synonymous with the gouging process. The rate at which metal is removed is based on the efficiency of the air stream, diameter of the carbon electrode, output of the welding power source and skill of the operator.

What should the arc voltage be for air carbon cutting?

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. The actual arc voltage in air carbon-arc gouging and cutting is governed by arc length and the type of gouging.
