Here you can find all the information on our seamless flux and metal cored wires and solid core electrodes.
MEGAFIL® seamless flux- and metal-cored wires are totally insensitive to moisture absorption. They can be stored for an indenite period of time. Like solid wire, however, they are copper-coated and direct contact with any liquid – particularly water – must be avoided to prevent the formation of rust on the wire surface. Rust is a potential source of weld metal hydrogen, but it can also cause poor wire feeding.
It is therefore recommended to store MEGAFIL® wires in a dry area – away from weather influences – and in their original packaging. Any sudden drop in temperature should be avoided to prevent the formation of condensate water. It is sufficient to slightly warm the storeroom during winter months. Partly used wire spools must be re-packed in their original plastic bag, carefully sealed, and stored in their original cardboard boxes.
