Mig welder terms and defintions

Here are some basic terms and definitions for a mig welder.

The MIG in Mig welder is an acronym for "metal inert gas" and the gas is most often argon. There is also MAG which stands for "metal active gas" and the gas here is usually CO2, or mixes containing CO2 or O2. Then finally there is MOG. MOG is not as easy to define. It possibly stands for "metal without gas". Basically, none of these acronyms really describe what Mig welding is all about and are a little deceiving. Mig welding is really using a wire feed to do the welding. You will notice all of the Mig welders on this site have a wire feed roller with them that dispenses the wire. These a great and easy to use little welders and highly recommended for a beginning welder or a hobbiest. Mig welding is an arc welding process where metals are joined by heating them with the arc. The arc is fed by a spool of metal filler. The metal is only used when the wire actually touches the surface you are working on or around.
