Yes, it is the SSC pedal and is very nice. Highly recommend. The tape idea is good. I was just going to take a Sharpie and do little tag'n.

Using my 250EX, try to match audible frequency. But, I'll play with it before I get too anal about this. A good welder should be able to set-up, and any critical chit deserves test pieces prior to the real deal.
I want this machine to provide a good stable arc and consistent performance, all the rest is up to me. Been busy and not able to do anymore testing, but maybe tomorrow.
Thanks for your input, appreciate it!
