Been following Ourei's advice from
this thread and it's been working great for me.
Just keep blowing on the coil as I burn, continue blowing for cool down after releasing the batt's manual button.
If I need to take a breath I let go the button, take a quick breath and blow a second or two to aid in cool down, then crank it up again.
I use my pt to burn as it will run 8-9 seconds before auto shut off so I can get good long burns, I count to 5-6 for each burn. Then count to 3 on cool down.
The other weird thing I do (and we all have some weird .... thing we doing in our pv maintennace), I use a drinking straw to blow through. Use it to aim the air right into the atty.
I keep burning until there is no smoke. Sometimes I have to dry burn a little while until it will start smoking. Then I keep going until it won't anymore. I might do it every 3rd day, I might do it twice a day, been working ok for me and my 510 attys so far.
ymmv....
