A welding power source must not be used continuously in long time without care. The rated duty cycle is fixed for safe use of welding power source without burned out of insulator. When a power source of a rated output 300A and a rated duty cycle 60% is used at 235A, calculate the allowable duty cycle of Manual Metal Arc (MMA) machine.
