Welding Aluminium Lead. The forehand also referred to as lead angle is the electrode angle that is always used for welding aluminum. Even if you are experienced in welding steels aluminum welding can present quite a challenge.
Also feeding aluminum welding wire during gas-metal-arc-welding GMAW presents a challenge because the wire is softer than steel has a lower column strength and tends to tangle at the drive roll. Because aluminium is such a sensitive material. The forehand also referred to as lead angle is the electrode angle that is always used for welding aluminum.

Pure aluminum melts at 1200F 650C and the oxide that protects the metal melts at 3700F 2037C. It is best to use a microfiber cloth that you have previously soaked with solvents such as butanol acetone or paint thinner. Typical grades include 4043A 5 Si and 5356 5 Mg. Aluminum and its alloys have a great affinity for oxygen.
