How To Welding Aluminum Mig. If it starts slowing down you may end up with a fused tip. The recommended electrode angle of travel is 5 to 15 degrees.
This ensures proper gas coverage of the weld puddle. If it starts slowing down you may end up with a fused tip. This process is a very smooth transfer of molten metal droplets from the end of the electrode to the molten pool.
Well then you have to pull.
But what if the position of the weld or other objects in the way prohibit using a push angle. The recommended electrode angle of travel is 5 to 15 degrees. When welding aluminum you are dealing with a much softer metal. Ideal numbers are between 25 and 30 cubic foot-hours.
