Don't need extra flux when welding, because this wire contain flux
Instructions for use of low temperature aluminum flux cored welding wire
Step 1: physical cleaning, polishing the surface.
Step 2: Heat the surface of the base material at the welding place until the temperature reaches the working temperature, so that the welding wire can be melted by the heat conduction of the base material to form a weld. When the surface temperature of the material is sufficient, the welding wire can flow and penetrate into the metal capillary well.
Step 3: When repairing thinner aluminum, just heat the aluminum base material to a suitable working temperature, and then use the welding wire to friction and fuse to form a weld. Only use a metal brush to melt the welding wire to fill the weld to form a weld.
Step 4: Small parts are welded with propane gas, and large parts are heated and welded with industrial gas or induction heating device. After welding, let it naturally slow down.
