Seamless flux and metal cored welding wire for all climate conditions. MEGAFIL® is hermetically sealed and resistant to moisture absorption. It means you can do perfect welds under extreme climatic conditions, even in tropical temperatures and high relative humidity. The filling remains dry throughout the entire process of storage and use, preventing hydrogen induced cracking caused by moisture in the consumable. MEGAFIL® requires neither special storage conditions nor re-drying prior to use.
