I have a sievert 96 handle with their jewellery head which I have been using for a few months..

I took a class recently and used an identical set up and found the torch had a much bigger range of flame... Despite having a flow regulator on my handle it's usually close to "on" or "off" when lit no matter how much I turn it...

I emailed the supplier the other day and they suggested the bottle is running out.. But im sure the tutor said her bottle has lasted "years" ... As I only make stuff at weekends it gets used regularly but not hours at a time...

I don't mind if it is empty but I am wondering if I have a handle with a faulty valve 😯

Anyone else using propane only had to replace a cylinder a lot? I got the biggest one I could carry as I can't leave it where my bench is.. 11kg

Well I never

Could be the handle could also be the regulator/vale on the cylinder it may be restricting the gas flow

An 11kg bottle should last a very long time with only occasional use. There's either a flow problem, as China suggests, or you've got a gas leak somewhere along the line.

I`ve been using Sievert torches for 35+ years,an 11kg cylinder will last up to a year on daily use [Full time !] with a jewellery burner.Don`t use reduction valve,use straight thro valve with jewellery burner to avoid any pressure drop.The other cause will be a dirty manifold at burner end.If old type sievert brner,unscrew head section and carefully remove "cap" from end of tube and wash out with warm soapy water or ultrasound.There is a tiny [I mean very tint]hole in this manifold to allow gas thro.Do not try to poke it clean unless you want a 12"+flame![Yes I did!"]If this don`t work unfortunately you`ll have to get a new burner as these manifolds are no longer available.If the burner is the newer sievert/primus then unscrew head then unscrew manifold section and do as above.Good luck.
Sometimes the gas companies either don`t rinse the cylinders properly and leave too much fluid/water in tem,this comes thro to the burner and congeals.Take cylinder and torch outside and blast gas thro without burner attached to get rid of build up.This won`t cure the problem but might prevent it happening again.
