Torching can and likely will weaken the ceramic and this is most important during the immediate moments after. Have spares in hand. And even when the ceramic cools give it a day to recover. try to avoid using it within the hour or longer of possible. It may feel cool and normal but the mounting process may find you breaking them easier.
This is not just a free tip. Its happened to me.![]()
Thanks for the Tip yankee. I normally make up my own ready coils, then when needing changed just pop in a pre-prepaired coil, so it may be a week before I put one into use, but it is really good to know.



however the 5 can be a tricky little bastage to get back out sometimes
