And that's why we are here with tech support to help in that, but there are threads that deal with this as well so you wouldn't have had to go it alone.
As far as the arc, is it like a small spark plug arc, sort of like little lightening bolts? This is the HF. Loosen them up to .035" to . 040". AND are you using your foot pedal? What is your start amps, upslope,downslope, and end amps set at? Are you in 2T or 4T? What are your panel amps?
