Clutch the electrode at a 10- to 15-degree angle from the vertical, sharp toward
the way of the weld. It can be significant to use this push process when MIG
welding light weight aluminum. The pull process would prevent the argon gas from
sufficiently in the weld, resulting in a great inconsistent weld.
Create a pool of molten aluminum with the electrode and gradually push the electrode
forward. Regulate the voltage in the welding machine to get spray transfer with
the aluminum electrode. In bottle of spray transfer, the electrode release small
droplets of the metal into the weld. This will results in a smooth weld and the
droplets do not get in the way while using the electrode arc.
