One of the most common welders is a MIG welder. The Mig Welder uses Gas Metal Arc Welding which works by a wire which is fed through a welding gun. The wire is the electrode. At this instant shielding gas is flowed through which protects the weld while it is setting and cooling down.
Most commonly used for this weld is carbon dioxide. It is the cheapest to use and also it makes great weld. Argon is used with carbon dioxide sometimes because it is a great mixture. It creates less mess, which makes the weld a lot cleaner. Argon alone can be used with aluminium for the best possible mold.
This method has great advantages over other methods in welding. Mainly because the welding gun has a control which will aim the electrode so that you do not hit an arc by accident. The gun is positioned in the right place and then all that is left for you to do is simply aim the gun and start your welding.
Alternating current will not give you a steady arc when welding, which is why MIG welders use a DC current. Using the inert shielding gases makes the welds smooth and clean with no slag to chip off. MIG welding is best used for thinner metals and weld sheet metal, because they can be welded at much lower power than other welders.
The tensioner on the wire is variable and you can also control the flow of the gas with a valve. Also adjusting the voltage of the MIG welder as well as the power as the wire feeds through is very useful for creating clean welds.
Filling the hollow core of the electrode with flux is flux cored arc welding, FCAW. You can use the mig welder without shielding gas, and also switch the polarity of the arc. This creates cleaner welds and is easy to use. This process is easy with a MIG welder.
