Oxygen is supplied in the liquid form. Industrial grade oxygen comes in various levels of purity broadly categorized as regular purity and high purity oxygen depending on the applications they have in the various industries.This grade of oxygen is mainly used in industries for cutting, brazing and soldering and also in the oxygenation of the water. Industrial oxygen vigorously supports combustion and significantly increases the flame temperature. It is widely used as fuel gas to give much higher flame temperature than air. It is also used as a shielding gas to stabilize the arc and increase fluidity.
