E4043 is a general purpose aluminum electrode for arc welding aluminum alloys.  The arc is stable and operates at low temperatures with a minimum of spatter and fuming.  The welds are strong, dense, and free of porosity on both production and maintenance applications.  E 4043 is a great choice when welding heat-treated aluminum parts.  This welding rod may also be used in brazing applications.
 
Typical Applications:  arc welding aluminums alloyed with copper, silicon and manganese, excellent for joining dissimilar grades of aluminum
