SMAW Welding questions with correct answers

Hot start provides an extra boost of current to help establish an arc when using electrodes that are hard to start. CORRECT ANSWER-T A constant-current welding machine is used for shielded metal arc welding. CORRECT ANSWER-T Current is the amount of electron flow through an electrical circuit. CORRECT ANSWER-T SMAW cannot weld carbon steel, low- or high-alloy steel, stainless steel, cast iron, or ductile iron. CORRECT ANSWER-F In North America, alternating current is rated at 50 Hz. CORRECT ANSWER-F Direct current is electrical current that flows in one direction only. CORRECT ANSWER-True A welding machine with a 60% duty cycle can operate at rated output for 6 min out of every 10 min without overheating. CORRECT ANSWER-True The workpiece lead is connected to the workpiece or to the workbench. CORRECT ANSWER-True Duty cycle is the percentage of time
