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 The directive EC 1194/2012 relates to mains voltage directional halogen lamps and means many common halogen reflector lamps such as D rated GU10's are affected. Iceland is following the same route as the EU. Montenegro banned incandescent bulbs over 100W from 1 July 2018, part of a phased ban. Norway has implemented the EU directive for the phase-out of incandescent light bulbs and has followed the same phase out route as the EU. There was a half-year delay in implementing the directive compared to the EU, but the phase out occurred at the same time since the affected light bulbs
