ARCAIR

ARCAIR is a brand of arc gouging equipment, including electrodes and torches, used in metal fabrication, foundry, and maintenance applications. The brand is associated with air carbon-arc gouging, a process that uses a carbon electrode and compressed air to remove metal. ARCAIR products are designed for use with direct current electrode positive (DCEP) polarity and require a minimum air pressure of 80 psi for torch operation. The product line includes pointed and jointed copper-coated electrodes in diameters from 3/16 in to 1/2 in and lengths from 12 in to 17 in, with current ratings from 250 A to 1,000 A. Electrodes are supplied in packs of 50 or 100. Torch models include the K3000 (rated 600 A) and K4000 (rated 1,000 A), each with a 10 ft cable length. Replacement parts such as swivel cables and valve and bonnet assemblies are available for specific torch series. 3G Electric stocks ARCAIR electrodes, torches, and accessories, supporting global procurement for plant engineers and maintenance managers who require consistent arc gouging consumables and tooling. The copper coating on electrodes provides electrical conductivity and oxidation resistance during the gouging process. Jointed electrodes allow for longer continuous operation by connecting multiple rods. Pointed electrodes concentrate the arc for precision work. All specifications are based on manufacturer part numbers and standard industry ratings. No additional certifications or performance claims are made beyond what is listed in the product data.

Frequently asked questions

Common questions about ARCAIR from 3G Electric.

What current ratings are available for ARCAIR pointed electrodes?

ARCAIR pointed, copper-coated arc gouging electrodes are available in current ratings of 250 A (3/16 in x 12 in, 50-pack) and 450 A (5/16 in x 12 in, 50-pack). Both are designed for DCEP operation. The 250 A electrode is suitable for lighter gouging tasks, while the 450 A electrode handles heavier material removal. These ratings are based on manufacturer specifications for the MPN 22033003 and 22053003 respectively.

What is the difference between ARCAIR K3000 and K4000 torches?

The ARCAIR K3000 torch is rated at 600 A and the K4000 torch is rated at 1,000 A. Both are manual air carbon-arc gouging torches with a 10 ft cable length and require a minimum air pressure of 80 psi. The K4000 is designed for higher-current applications, allowing faster metal removal rates. The K3000 is suitable for medium-duty work. Replacement parts, such as the 360-degree swivel cable for the K4000, are available separately.

Are ARCAIR jointed electrodes available in different sizes?

Yes, ARCAIR jointed, copper-coated arc gouging electrodes are available in 3/8 in x 14 in (600 A, 100-pack, MPN 24062003) and 1/2 in x 17 in (1,000 A, 100-pack, MPN 24084003). The jointed design allows multiple electrodes to be connected end-to-end for continuous gouging without stopping to change rods. Both are rated for DCEP operation.

What replacement parts are available for ARCAIR torches?

3G Electric stocks replacement parts for ARCAIR torches, including a 360-degree swivel cable for the K4000 torch series (MPN 70084207) and a valve and bonnet assembly for the K-5 torch series (MPN 94104023). These parts allow maintenance of torch functionality without replacing the entire unit. Always verify compatibility with your specific torch model before ordering.

What is the typical application for ARCAIR pointed electrodes?

ARCAIR pointed electrodes are used for precision arc gouging, such as removing welds, cutting grooves, or preparing surfaces for repair. The pointed tip concentrates the arc for controlled metal removal. They are commonly used in fabrication shops, foundries, and maintenance operations where accuracy is required. The copper coating helps maintain electrical contact and reduces oxidation during the gouging process.

Does 3G Electric supply ARCAIR products?
