3.1.2Function of the Stick Electrode Coating

Stabilization of the

arc and lonization

of the arc space

Protection of the weld

metal from atmospheric

oxygen and nitrogen

This protection is achieved by the generation of shielding gases and slag during the

melting of the electrode.

Compensation of alloy burn-off.
