Helium / argon mixtures are sometimes used for their higher heat characteristics. Gas mixtures, usually 25% helium and 75% argon are sometimes used and can help to increase travel speeds when AC - gas tungsten arc welding.

R407C Applications
R407C is a zeotropic blend composed of difluoromethane (R32), pentafluoroethane (R125), and 1,1,1,2-tetrafluoroethane (R134a). Each component serves a specific function:
R32 provides heat capacity.
R125 reduces flammability.
R134a lowers operating pressure.
R407C is recognized as a long-term replacement for R22, sharing similar performance characteristics. It is widely used in air conditioning systems and non-centrifugal refrigeration systems for medium and high temperature applications, making it an ideal solution in a variety of HVAC setups.

Helium is colourless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Itsboiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions.
Helium is the second lightest element and is the second most abundant element in the observable universe.
Usages:
1. Helium is used as a shielding gas in arc welding processes on materials that at welding temperatures are contaminated and weakened by air or nitrogen.
Helium is used for many purposes that require some of its unique properties, such as its low boiling point, low density, low solubility, high thermal conductivity, or inertness. Of the 2008 world helium total production of about 32 million kg (193 million standard cubic meters) helium per year, the largest use (about 22% of the total in 2008) is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners. Other major uses (totalling to about 78% of use in 1996) were pressurizing and purging systems, maintenance of controlled atmospheres, and welding. Other uses by category were relatively minor fractions.
