Hi Dom,

I was pondering the temp reduction for the tip after we had our 
discussion the other day...

The current is fully off for half of the cycle and reduced by some 
percentage on the other half, but I can't remember the procedure  to 
determine it....The figure .7 sticks in my mind...

That percentage would probably be close to the idling tip 
temperature, influenced by radiation and some other factors of course...

These kind of things (queries) pop in, but the answerers don't pop in 
as easily any more!!

Ready for a math lesson, tnx!!
