Premium range of shielding gases for welding

ARCAL™ is Air Liquide's leading brand of high-quality, ready-to-use shielding gas solutions for your welding applications. It comes in four ready-to-weld argon mixture solutions that cover virtually all welding application needs.


ARCAL™ 1 is our primary high-quality shielding product for most welding applications. These include TIG and plasma welding of all materials including titanium, MIG welding of aluminum and copper alloys, and universal root shielding of all materials. 99.998% argon ensures reliable integrity of the weld bead making ARCAL™ 1 the pure gas solution for your arc welding needs.


ARCAL™ 12 is the most efficient gas mixture for all stainless steel MAG welding. This product is carefully selected to match with chromium – the key component of steels for corrosion resistance. From household appliances to chemical vessels and pipes, for both austenitic and ferritic stainless steels, ARCAL™ 12 offers brilliant welding performance with a clean weld aspect.


Mixed for high-travel speed and high-deposition rate MAG welding of carbon steels, ARCAL™ 21 is the essential arc welding gas when weld time is a critical factor and is ideal for automatic and robotic applications. Highly adaptable with low fume and spatter emissions that reduces post-welding operations, characteristics of ARCAL™ 21 make it the choice when high productivity is needed without sacrificing quality.


ARCAL™ 5 is the ready-to-weld solution for MAG welding of heavy carbon steel structures. From earthmoving and agricultural equipment to bridge building and ship modules, ARCAL™ 5 was engineered with heavy use in mind. No matter the surface – oxidized or contaminated, gapped or mismatched – it is extremely tolerant to preparation. ARCAL™ 5 is ready for your toughest and most challenging welding applications.
