* Machine strikes an arc between the work and a consumable wire electrode, melting a pool of metal
** Welding isn't like soldering, welding melts the pieces of metal and allows them to flow together and mix with the filler material. When it re-solidifies it's one continuous piece of metal
* Wire dips in and out, adding metal to the pool
* Gas shields the hot metal from the air
