Air Carbon Arc Cutting (CAC-A) ~ A cutting process by which metals are melted by the heat of an arc using a carbon electrode. Molten metal is forced away from the cut by a blast of forced air. To remove large amounts of metal, look for a welder that can use carbons of at least 3/8 in diameter. Consumables: carbon electrodes, compressed air supply.

MIG (GMAW or Gas Metal Arc Welding) ~ An arc welding process which joins metals by heating them with an arc. The arc is between a continuously fed filler metal (consumable) electrode and the workpiece. Externally supplied gas or gas mixtures provide shielding. Common MIG welding is also referred to as short circuit transfer. Metal is deposited only when the wire actually touches the work. No metal is transferred across the arc. Another method of MIG welding, spray transfer moves a stream of tiny molten droplets across the arc from the electrode to the weld puddle. Consumables: contact tips, shielding gas, welding wire.
