6. Oxidation is just air, oxides from the air, getting into the weld. If you allow oxygen or other gases from the air specifically into the weld pool, and other gases in the air into that weld pool, you are going to get oxides in the weld pool.7. The advantages of
is that it is used to get better arc action. Less spatter, on your base metal when welding.B. When you get into other metals beyond steel and different modes of transfer, you are going to have to change up the gas mixture or the type of shielding gas being used.Wire Drive System1. For those of you that have done some welding in the past or maybe using some older equipment, you are going to note that the wire feeds from the drive rolls down on the newer machines.2. Different types of wire need different kinds of tension. So for example, aluminum wire, if you are running a push-pull setup, and you are running aluminum wire through this machine, you are not going to use near the tension that you would use on mild steel because aluminum is very very soft and you are going to cause it to not want to feed through that lead.3. It is very important and a lot of people do not think this is important for whatever reason, to change the drive rolls to match the diameter of the wire that you are using.4. There are even specific types of drive rolls available that have little teeth in them for other applications.Changing Filler Wire Spool1. This is where the shielding gas is going to be directed out onto the base metal.2. And I am using these welder-style or welder's nozzles. These are great for most MIG and TIG applications because of the way they are designed - they are designed for this very reason.3. Contact tip - this is what carries the electrical current from the power source that I am going to show you inside this lead to the weld itself.
