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 to delay new energy efficiency standards for light bulbs until 1 January 2014, when it will become illegal to import inefficient incandescent lighting across the country. In December 2011, Ontario Energy Minister [Chris Bentley] confirmed that Ontario is scrapping the five-year-old plan "to avoid confusing consumers". The Energy Star program, in which Natural Resources Canada is a partner, in March 2008 established rules for labelling lamps that meet a set of standards for efficiency, starting time, life expectancy, colour, and consistency of performance. The intent of the program is to reduce consumer concerns about efficient light bulbs due to variable
