How to dry out 6018 welding rod?

Dry E6018 welding rod in a drying oven at a temperature of 500°F to 800°F (260°C to 425°C). After keep in holding oven at a temperature of 50°F to 250°F (30°C to 140°C) for welding application.

The 6018 welding rod must be completely dry before beginning a weld. Any moisture on the rod will cause problems with the weld.

To dry out the rod, place it in a drying oven at a temperature of 500 degrees Fahrenheit to 800 degrees Fahrenheit.

Once the rod is dry, place it in a holding oven to keep it at that temperature until you are ready to use it.
