Evening,
I know this post is madly late....but I have just made my first tentative steps into the world of PMC...very excited by the whole prosect of learning to work with it

I used my micro torch (that came from Cooksons) for the first time, all went well....but once switched to the off position I could still hear a hissing sound for ages. It has stopped now, but am quite nervous about these things (as is my OH who for some reason strongly dislikes the thought of me using one of these when he isnt in the house!!! No iea why....)

So- I am leaving windows open, and shutting the cats out of the living room for the night....is this normal, am I over reacting?? I mean the torch doing hissing for a good few minutes after being switched off????

Advice greatly appreciated.
