Some call them rosebuds, others call them multiflame heating heads, and a few call them heat sticks. No matter what you call torch attachments, this article is a frank discussion about these tools that use oxygen and a fuel gas to make a lot of heat quickly. When used properly, they can make quick work of many heating jobs.
