How to tell if shielding gas is contaminated? : Welding - reddit

Unless specified, the general rule of thumb is the point should be 1.5x the diameter of the tungsten, with a flat on the end 20% the diameter. Hangout is also a bit too long. When you have a high rate of gas flow and tungsten hanging all the way out like that, the gas flow will actually draw in oxygen and affect your shielding.

A Comparison Between Water-Based and Solvent-Based Coatings

Solvent-Based Coatings The liquefying agents in solvent-based paints react in a specific manner: when oxygen and chemicals react, the liquefying agents evaporate. Drying times can be reduced by the reaction being sped up because the air surrounding the process is moving. Compared to water-based coatings, one major advantage is possessed here.
