The tip of a welding or cutting torch is where the action is (see Figure 1). Welding tips usually produce positive pressure (higher than 1 pound per square inch [PSI]) and are used at equal pressures of acetylene and oxygen. These single-hole copper-alloy tips are attached to a torch handle...

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.
