the intense heat is created by the arc.the electric arc is the best source of the heat energy.the arc is able to melt base metals.sometimes the arc is created between the two non-consumable electrodes.there are two types of current, alternating and direct.the depth of fusion is named penetration.the electrode holder is used for holding an electrode.when the electrode is in contact with the work, the circuit is completed.the electric current and polarity, both straight and reverse are an important factor in producing high quality welds.the ground cables connect the base metal with a source of energy.the filler electrode is a conductor and at the same time a consumable metal.intense heating results in melting the base metal and the electrode.
