OVERVIEW

Master the Heat with the ESAB Rosebud #55

When you need to bend a 1-inch steel plate or straighten a twisted frame, a standard welding tip just won't cut it. You need the ESAB 998797 Rosebud O-A Tip AY #55. This is the heavy artillery of your oxy-fuel kit. Designed for professional welders and fabricators, this multi-flame heating head—commonly called a "rosebud"—pumps out massive amounts of heat, allowing you to soften thick metal quickly and evenly. It is specifically built for use with Acetylene, giving you that intense, controllable heat that propane alternatives sometimes struggle to match on specific steel grades.

The #55 size indicates a serious capacity for heat output. Whether you are in an automotive frame shop, a farm repair center, or a heavy fabrication floor, this tip allows you to work faster. Instead of waiting forever for a spot to turn cherry red, the multi-port design spreads the flame across a wider area, soaking the heat deep into the metal. This is crucial for preventing cracking during welding by ensuring your preheat temperature is reached thoroughly and maintained.

Durability is built into the ESAB name. The tip features a heavy copper end that resists deformation from accidental bumps and withstands the extreme heat reflected back from the workpiece. It attaches securely to compatible Purox and Oxweld style handles, giving you a balanced and reliable tool in your hand. Remember, this beast drinks fuel—make sure your acetylene supply is up to the task so you can keep the flame steady and safe. Upgrade your torch setup with the ESAB 998797 and stop struggling with undersized heating tips.

Why Choose This Rosebud?

  • Fast Heating: Multiple flame ports deliver BTUs fast, reducing wait time.
  • Rugged Build: Solid copper construction stands up to daily shop abuse.
  • Precision Control: Designed for stable flame characteristics without sputtering.
  • Versatility: Perfect for everything from freeing rusted nuts to bending heavy bar stock.

FAQ

This tip is designed exclusively for Oxy-Acetylene. Do not use it with Propane, Natural Gas, or MAPP gas as the injector/mixer design is specific to Acetylene flame propagation rates.

The ESAB 998797 typically fits heavy-duty Purox and Oxweld style handles (such as the W-300 or W-400 series). Always check your torch handle's compatibility chart for 'Type 55' heating heads.

Because rosebud tips consume a large volume of acetylene, you must ensure you do not withdraw more than 1/7th of the cylinder's capacity per hour. For a size #55 tip, you may need a large cylinder or multiple cylinders manifolded together to prevent drawing acetone into the regulator.

No, this is a heating tip (rosebud). It does not have the central oxygen jet required for the oxidation process used in cutting. It is strictly for heating, bending, and preheating.

Use a standard tip cleaner set. Select the wire size that fits the small flame ports snugly but without forcing it, and move it in and out to remove carbon buildup. Do not use a drill bit as it may enlarge the holes.

Popping or 'backfire' can occur if the tip is overheated, if it touches the work, or if gas pressures are too low. Ensure you are using the recommended pressure settings and that the tip is not starved for gas.

Yes, most ESAB heating head assemblies like the 998797 include the necessary mixing chamber or are designed to work with the mixer already in the compatible torch handle. Check the specific breakdown, but 'Assembly' usually implies it is ready to thread on.

A welding tip concentrates heat in a tiny point, which can melt the surface before the core is hot. A rosebud spreads the heat over a larger area, allowing for deep thermal saturation without surface melting.
