This may change your mind.

These are the measurements on my oscilloscope. Using PWM pin 4 of an Arduino Mega at 980Hz.

  1. My terminology is correct.
  2. I have already mentioned latency.
  3. A PWM signal of 490Hz or 980Hz can hardly be compared to the working patterns of a welder.
  4. There are plenty of resources on the net, without me having to explain PWM.

Woha, calm down fella...

1) I was questioning my own knowledge and terminology
2) I never said you didn't?
3) I wasn't comparing the patterns... I was trying to clarify that the meaning of the term "duty cycle" could be confusing to some readers, as it has a different meaning in the electrical/electronics world depending on context
4) I did not ask for a lesson on PWM, and I did not doubt you were seeing the results you reported - I was simply seeking to clarify, your tying of the PWM (% of cycle on time) to voltage.
