Blue Demon Aluminium ARC Welding Rods 

4043 Electrodes

2.4mm x 0.45kg

E404324M/300016H (Bossweld)
Blue Demon - 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. 
E4043 is a great choice when welding heat-treated aluminum parts.
This welding rod may also be used in brazing applications.
