Basic Information About A MIG Welder It is the MIG welder that is considered as neo of the most used welder of today. It is this type of welding that uses the process known as the GMAW or the gas metal arc welding. The electrode which is the wire is fed into the welding gun. It is also here that there is a use of the continuous flow of inert gases. The gases are used to protect the weld as it cools. It is the carbon dioxide gas that is commonly used for general welding. Creating a good weld can be done with this gas and it is also very cheap. Argon can also be mixed so that the arc will have less spatter which can give you a cleaner weld. It is the pure argon gas that you should use the moment that you will weld aluminum. It is when you will be using the GMAW that there will be a number of benefits that you can get compared to all others. It is by using the welding gun that you can position the electrode properly without accidentally hitting any arc. The moment that you have it in the right position, then all you have to do is to pull the trigger.

Due to the inert shielding gases that you can create seams that are clean and smooth. It is this one that you will not be needing to chip off any slag. Whe y are working with sheet and thin metals, then a MIG welders are also perfect for it. By welding in lower amperage that you will be able to do this one. It is a MIG welder that also use DC in order to strike the arc. You will not be having a steady arc the moment that you will use AC. The moment that you will be using a MIG welder, then it is possible to adjust the voltage, amperage, and speed. It is a MIG welder that you can also control the flow of gas because of the valve that it have, making the tensioner on the welding wire variable. You can also use a MIG welder without using any gas at all. It is this one that is called as an FCAW or flux cored arc welding. A hollow core that is filled with flux is what is being used in this one. It is possible that you will do the FCAW outdoors as you will not be worrying with any shielding gas being blown away. It is by using the flux core wire that is more hotter which is why it is also great for thick metals. Similar to the ordinary welder, there are slags that you need to be removing in a FCAW. Thinner and light sheet metals can also be weld by an FCAW.
