Auckland Club Meeting

Grant Williams will give a display using Liquid Nitrogen (-196 degrees Celsius), this can be used for freezing food stuffs to shrink fitting bearings and burning the odd wart or two off. We will also have some Dry Ice to play with as well (-78 degrees C). Bring all your questions that need clearing up about any gas, especially acetylene, oxygen, argon and argon mixes used for welding. If you have never seen liquid nitrogen before then you will definitely find this an interesting evening.
