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. It is this one that the weld is protected while it cools. A gas known as carbon dioxide is what is used for general welding. Creating a good weld can be done with this gas and it is also very cheap. You will have a cleaner weld the moment that you will mix argon gas and it also will create less spatter. The moment that you will be welding aluminum, then you should use pure argon gas . 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. This is because the welding gun is much better as you can position without striking any arc. It is pulling the trigger that you have to do the moment ta you have the gun positioned at the exact spot.

Due to the inert shielding gases that you can create seams that are clean and smooth. You will no longer be chipping off any slag. The moment that you will be working with sheet and thin metals, then a MIG welder is also good for that. By welding in lower amperage that you will be able to do this one. For it to strike the arc, a MIG welder uses DC to do that. You will not be having a steady arc the moment that you will use AC. The voltage, amperage and the speed can also be adjusted in a MIG welder. It is also possible to adjust the tensioner on the welding wire as it also has a valve to control the flow of gas. The MIG welder that you have can also be used without the use of any gas. It is this one that is called as an FCAW or flux cored arc welding. The FCAW uses a wire that is hollow and filled with flux. It is possible that you will do the FCAW outdoors as you will not be worrying with any shielding gas being blown away. If you are working with thick metals, then the FCAW is also great as the flux core wire is much hotter. The moment that you will be using an FCAW, then you will be removing slags which are similar to an ordinary welder and that is the downside of it. It is also this process that can also be used to weld thinner and light sheet metals.
