Storage
Storage and Re-baking It is recommended that the WB range of electrodes are stored in a dry heated store at
a minimum temperature of 18C, and a maximum relative humidity of 60%. To avoid
damage to the coatings no more than 6 cartons should be staked on top of another.

Re-drying
Re-dry @ 350C for 2 hours and then transfer to holding oven and hold @ 100 -
200C, or 50-100C in heated quiver.

Current Conditions AC OCV70 DC +/- and Welding Positions
