Calcite
Calcium carbonate used as a slag former and gas shield source in electrode coatings.
Calcite decomposes in the arc, releasing carbon dioxide that shields the weld pool from the atmosphere and leaving calcium oxide behind to form part of the slag. It does two jobs at once, which is why it appears in so many coating formulations.
The lime it leaves behind raises the basicity of the slag, and basicity is what governs how much oxygen and sulphur end up in the deposit.
