Inert gas can be found which is inexpensive and common. For example, carbon dioxide is sometimes used in gas mixtures for GMAW because it is not reactive to the weld pool created by arc welding. But it is reactive to the arc. The more carbon dioxide that is added to the inert gas, such as argon, will increase your penetration. The amount of carbon dioxide is often determined by what kind of transfer you will be using 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%
Phase-out of incandescent light bulbs 2010 in favor of more energy-efficient fluorescent globes to help cut greenhouse gas emissions and household costs during her closing remarks at the Philippine Energy Summit. Once put in effect, the country will be the first in Asia to do so. The Government will stop all production, import and sales of incandescent light bulbs by or before January 2014, as part of efforts to save power and to help cut greenhouse gas emissions. Phase out of 60W and over incandescent light bulbs has been implemented from 1 January 2012. As a measure to increase awareness a national awareness campaign has
