Burners for sievert professional torch.

I have been using the above with the needle flame 3537 for my small soldering jobs and then a large unwieldy go gas torch for larger bits. I want to get a new burner for my sievert kit instead. I do have a general burner 3941 but that is like taking a sledge hammer to crack a walnut!.....Which burner would you advise? I assume a needle type flame is most controllable.??? The specific problem I have met is soldering heavier bangles. The needle point 3537 just doesn’t have the welly to heat up that weight of silver.

When I bought my sievert decades ago I bought 3 burners, the needle, a medium and the big scary one The needle has never been out of its box and the only time I use the big one is if I’m making cuffs and I need a bit of welly. I’ve just about got used to the noise and size of flame but scared myself the first time. I use the medium one for all my soldering and have a wee cooks torch for making balls or balling up ear wires. Hope this helps Caroline Ps I would give you the number but not sure it’s the same one as it’s so old

I’m assuming that STD doesn’t stand for what came up when I searched so sorry I’m being a big dim!
The number on the nozzle I use is 3940 but not sure if that relates to present parts

Burner 3940.....perfect ! The ideal balance. A controlled dragon compared to the 3941 which is good for plumbing!
