Answer Posted / Bharti Kathuria
Arc welding machines require a parallel earthing system because they draw high currents and generate large amounts of heat. Parallel earthing ensures that the welding machine is earthed directly, reducing the resistance in the earth circuit and minimizing the risk of ground loops. Each machine is connected to the earth pit by separate wires during earthing to ensure a safe and effective ground connection for each welder. The advantages include reduced potential for electrical shocks, improved equipment performance, and enhanced worker safety.
