Try the pedal on a different machine.

We send them back to miller, it just seems that the machines that have actual high frequency start never seem to have a problem.

I've been told the miller maxstar has a capacitive discharge arc start and not high frequency. I was wondering if that is why the maxstar seems to lose it's striking ability as it racks up the hours in use

what is the difference between capacitive discharge arc start and high frequency arc start
