MIG welding, also known as metal inert gas welding, is one the most common techniques in welding often used to fabricate metals thicker than inch. This method is quite similar to TIG welding; the main difference is that the electrode is consumable. It utilizes the wire electrode and also needs continuous voltage supply.
In this technique, the MIG gas torch contains a wire fed through the handle which transmits an electric current to the piece, and it brings in a filler metal during the melting process. One of the advantages of this welding method is that it requires minimal post-weld cleanup and the easiest process to learn and do among the welders. Many people can learn to run good beads with MIG in a few hours. It can also be used to weld stainless, mild steel, and aluminum metals.
Here are some of the basic yet important tips to make your MIG welding project safe, hassle-free, and successful at all times:
Use a good ground clamp. Choose the one that has a very strong spring holding. The stronger the spring holding it shut, the better the earth connecting will be.
Always clean the ground surface. A dirty ground will result in unnecessary spattering and popping, and will prevent you from operating at the power it is set to.
Pay attention to your stick-out. For the unacquainted, stick-out refers to the distance from the mig welding tip (also known as contact tip) to the arc. In most cases, opt for a quarter-inch of stick-out for the best outputs. When using a longer the stick-out, a cooler weld is needed. Some experts also recommend the use of a wire stick-out as small as possible; however, you need to be very extra careful not to fry the tip.
Choosing the right wire is very important. Bear in mind that not all welding wires are created the same. Welding projects involving thick metals usually call for .045" or .035" size wire.
Get a quality auto darkening helmet. MIG welding produces lots of heat and lots of harmful light, thats why you need to wear this to protect yourself. Harmful UV rays can quickly damage your eyes.
