Why would you use hot start on an SMAW welding power supply? D It provides extra amperage for 1/10 th of a second to help start the arc The electrode burns hotter allowing it to melt more quickly into the weld pool It optimizes the size and shape of the arc cone It provides deeper penetration throughout the weld

Answer 1

The correct answer is:D. It provides extra amperage for 1/10th of a second to help start the arc.Hot start on an SMAW (Shielded Metal Arc Welding) power supply is used to provide an initial surge of current to help initiate the arc more easily. This extra amperage for a brief moment helps the electrode to melt and form the arc, making it easier to start the welding process.
