Moisture is still the main enemy for welding consumables. The minerals being used to form the slag that covers the weld pool are highly hygroscopic and should be taken very seriously for submerged arc powder and covered stick electrodes. Moisture also know how to find his way very quickly at folded flux cored wires and it only takes a few hours exposure to humidity before the general requirement of less than 5ml hydrogen in 100gr weld metal is exceeded. The most important steps to prevent hydrogen induced cracking are:
1) Use airtight packing for covered electrodes
2) Use seamless fluxcored wires for Mig/Mag welding
3) Always redry sub arc powders directly before use
