In What is a Low-Carb Diet?, I outline three approaches to low-carb eating, only one of which focuses on ketosis as a goal throughout the diet. Diets such as the Atkins Diet start out as a very low-carb ketogenic diet, but as people add carbohydrate, many or most will be eating too much carbohydrate to be in ketosis.
At the core of any custom motorcycle project is the welding process used to join the tubing that makes up the bike's frame. This article will discuss how both MIG and TIG welding fit into this process and how even a novice welder can get started. (As seen in the Welding Journal, October 2005)
It comes out of the same nozzle your welding wire is fed through so it literally creates a protective cloud around the arc as you're welding. A MIG welder is also a wire-feed type welder. The metal that it uses to create the weld material is held on a spool inside the welder. The type of material it uses depends on what type of metals you're joining, but it's always a metallic wire. For beginners, or for welders who need ultimate portability, some welding wire contains flux inside it, eliminating the need for a separate tank of welding gas. This works, but is inferior to a proper gas setup.
