The main difference between the tungsten arc welding process and the MIG process is indifference of the electrodes. Whereas the tungsten electrodes at the tungsten arc welding process are only arc producing electrodes (non depositing electrodes), the almost endless spooled wire electrodes are at gas metal arc welding arc producing electrodes and depositing filler material. The arc space, the dissolving filler and the melting pool are screened from the air atmosphere by the active and inert shielding gases. The operative range of steels and non iron metals determines the choice of wire and shielding gas combinations. In the case of steel welding only active shielding gases are used and in the case of treatment of non iron metals inert gases are usually used.
