Argon is far more narcotic (about 2.3 times more) than the cheaper and more readily available nitrogen at depth, so it loses out to nitrogen in all roles as a primary breathing gas. If the maximum operating depth for air owing to narcosis is taken to be 40 metres (130 ft), then for 20% argox (20% O 2 , 80% Ar) it would be 14.5 metres (48 ft).
The more carbon dioxide that is added to the inert gas, such as argon, will increase penetration. The amount of carbon dioxide is often determined by what kind of transfer is used in GMAW. The most common is spray arc transfer, and the most commonly used gas mixture for spray arc transfer is 90% argon and 10% carbon dioxide.
Argon-39, with a half-life of 269 years, has been used for a number of applications, primarily ice core and ground water dating. Also, potassium–argon dating and related argon-argon dating are used to date sedimentary, metamorphic, and igneous rocks. [25] Argon has been used by athletes as a doping agent to simulate hypoxic conditions.
Argon with 25–35% helium and 1–2% CO 2 provides high productivity and good welds on austenitic stainless steels. Can be used for joining stainless steel to carbon steel. Argon-CO 2 with 1–2% hydrogen provides a reducing atmosphere that lowers amount of oxide on the weld surface, improves wetting and penetration. Good for austenitic ...

In such puzzles shaded squares are typically limited to about one-sixth of the total. Crossword grids elsewhere, such as in Britain, South Africa, India and Australia, have a lattice-like structure, with a higher percentage of shaded squares (around 25%), leaving about half the letters in an answer unchecked. For example, if the top row has an ...
[5] Non-consumable electrode processes, such as gas tungsten arc welding, can use either type of direct current (DC), as well as alternating current (AC). With direct current however, because the electrode only creates the arc and does not provide filler material, a positively charged electrode causes shallow welds, while a negatively charged ...
