What is the relationship between duty cycle and current output in a welding power source?

What is the relationship between duty cycle

Multiple choice — select the best answer

ACurrent output has no effect on duty cycle
BDuty cycle only depends on voltage, not current
CAs current output increases, duty cycle decreases
DAs current output increases, duty cycle increases

✓ Correct answer: C. As current output increases, duty cycle decreases Duty cycle and current output have an inverse relationship. Higher current outputs can only be sustained for shorter periods (lower duty cycle) due to heat generation in the power source components.
