Very slow though. I've got a monument electrical inductance soldering machine and it takes around 4 times as long as with a blow torch. Very handy if you're working very close to highly flammable materials. I was doing a boiler and cylinder swap a few years ago and the cylinder cupboard was lined with polystyrene tiles. Even with a heat mat the tiles would have melted using a blow torch. The customer queried why I was using it and I explained about the fire risk and he seemed quite impressed. He was even more impressed next day when I went back and the front page of his paper had a picture of a listed building burnt to the ground by a plumbing apprentice.
I always remove the gas bottle. I heard that you can be fined up to £1000 if the police stop you and see it. Anyone know if that's actually true?
I've heard of them leaking and blowing up too along the way
I dont use any , if it goes of the alarm I let it run ......
,but if its one of them places where the fire alarm is linked worth the local fire station then is a big risk as the could be charged for a them coming over and not been a real fire (bit disappointing really ) pmsl
