2 seconds is a long preflow time. You are aware that the arc will not even try to start for two seconds from when you push the switch? The HF should be able to jump a gap of at least .125-.250". If it doesn't transfer to the main arc, check for possible ground issues. One person had the ground wire come out inside the rubber boot at the plug.

I've had the preflow all over the place. The 2 seconds is a +/-.
Yes, I can hold it 1/2" away and still get spark.
I'll have to check that.
