MIG welding is also called Metal inert gas welding, gas metal arc (GMAW) welding. MIG welding uses an arc of electricity that creates a short circuit amidst a constant anode and a cathode. The short circuit produces heat and a non-reactive gas. This melts metal, enabling it to be mixed together. After the heat is removed, the metal cools down and then solidifies, creating new fused metal. MIG wire is used in MIG welding. Tungsten inert gas (TIG) welding utilizes a non-consumable tungsten electrode that produces the electric arc for the weld. Unlike MIG welding, TIG welding does not require additional metal to be added.

Arc welding is any welding process that uses electricity, which includes MIG, TIG, and SMAW. SMAW Shielded metal arc welding is most commonly referred to as stick arc welding. In SMAW welding the stick electrode contains a flux that keeps the atmosphere from contacting and contaminating molten metal. It is a good choice for welding thicker metals. It is a manual process, that is hard to get a hand of. yet once done. MIG welding is a semi-automated process that is a much better option to use on thinner metals. It is easier to get hang of than SMAW welding. A welding MIG wire is used in the MIG welding process. TIG welding is the hardest as compared to SMAW & MIG welding. It is capable of producing an autogenis weld which is one does not use any filler. These are some differences in arc welding processes.

Go to your local welding supply store. A TIG welder is a specialized welder that cannot be found at a building supply store. Stores like Maine Oxy-Acetylene Supply or Grainger Industrial Supply will carry them. Look in the classifieds of publications like Uncle Henry's. There you might find a TIG welder that someone is selling—and it may be at a good price. Be sure to ask the owner questions and take a look at the TIG welder before buying it. Explore eBay. Yes, even eBay has TIG welders. You'll need to ask the buyer questions about the welder's history and more. Perhaps, if the seller is near enough, you might be able to pick up the TIG welder yourself and save on shipping. Visit online retailers. Retailers like Welders Direct or Welding Mart carry TIG welders and would be able to answer any questions you might have (see Resources below). Consider the manufacturer of the TIG welders themselves. Lincoln, Miller, Hobart and others have their own websites. Call the companies directly and ask a lot of questions. These vendors are the best product source for welders (see Resources below).
