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.
