Mercury and carbon two electrodes can't be used with an inactive or inert material.
<h3>What is an electrode?</h3>
The electrode is the element which is used to complete the electric circuit in welding. Some time electrode is connected with the positive terminal and sometimes with a negative terminal, it depends on the requirement of the welding process.
Inert electrode is an electrode that serves only as a source or sink for electrons without playing a chemical role in the electrode reaction. Precious metals, mercury, and carbon are typically used as inert electrodes.
Therefore, neither of the two electrodes can be used with an inactive or inert material.
