WebThe major equipment is the power source of SMAW process that may include- welding transformer, a dc rectifier or a dc generator set. A consumable electrode is used which has protective coating which melts when heat is produced on the weld area. When the coat melts, it provides shielding to weld pool from gases like oxygen and other impurities. portable toilet shower rental
