## HOW ARE METALS CLASSIFIED?
Metals play a major role today in all areas of society’s development. These materials are present daily in…
Covered electrodes require an amperage range to melt properly; it is important to know the current characteristics, penetration type, and arc transfer. The table below indicates the main coating characteristics.
