OVERVIEW

Heavy-Duty Oxy-Acetylene Heating Performance

The ESAB #250 Multi-Flame Heating Tip (12Y44) is a high-performance industrial nozzle designed for heavy-duty heating applications using oxy-acetylene gas. Commonly referred to as a "rosebud" due to its multi-port face, this tip is engineered to deliver a massive amount of heat quickly and efficiently to a localized area. It is an essential tool for metalworkers, fabricators, and structural steel professionals who require rapid thermal transfer for processes such as preheating prior to welding, flame straightening, and hot bending of thick steel sections.

Precision Multi-Flame Design

Unlike standard cutting tips that focus a single stream of oxygen to sever metal, the #250 heating tip features a cluster of precision-drilled flame ports. This configuration produces a broad, soft, yet intensely hot flame that wraps around the workpiece, ensuring uniform heat soaking. This is critical when working with materials that require specific interpass temperatures or when relieving stress in welded assemblies. The tip is constructed from high-quality copper and brass alloys to resist the intense reflected heat generated during operation, ensuring a long service life even in demanding environments.

Operational Safety and Efficiency

Designed specifically for Acetylene gas, this tip maximizes the high flame temperature characteristics of the fuel. Users must be aware of the withdrawal rate limitations of acetylene cylinders when using large heating tips like the #250. Because multi-flame tips consume significant volumes of gas, it is often necessary to manifold cylinders together to prevent solvent withdrawal and ensure a stable flame. This tip is compatible with standard heavy-duty torch handles, making it a versatile addition to any professional oxy-fuel outfit.

Applications

  • Preheating: Raising the temperature of thick plate or pipe before welding to prevent cracking and ensure proper fusion.
  • Straightening: Applying localized heat to correct distortion in structural beams and frames.
  • Bending: Heating bars, pipes, and flats to make them malleable for forming.
  • Descaling: Using thermal shock to remove heavy rust or scale from metal surfaces.

FAQ

This tip is designed specifically for Oxy-Acetylene gas mixtures. It should not be used with Propane or Natural Gas, as those fuels require different tip designs (typically recessed) to maintain a stable flame.

A 'rosebud' is a common industry term for a multi-flame heating tip. It gets its name from the appearance of the tip face, which has a circular pattern of flame ports resembling a flower.

Heating tips usually attach directly to a welding handle or a specific heating adapter, not a cutting attachment. You typically remove the cutting attachment and screw the heating assembly onto the torch handle.

You need heavy-duty regulators capable of flowing the high volume of gas required by a large multi-flame tip. Standard light-duty regulators may starve the tip, causing flashbacks or unstable flames.

Acetylene cylinders should not be withdrawn at a rate exceeding 1/7th (or conservatively 1/10th) of their capacity per hour. Large heating tips like the #250 consume a lot of gas, so you may need to manifold multiple cylinders or use a large industrial cylinder to operate safely.

MFA tips are designed for Acetylene gas. MFN tips are designed for Natural Gas or Propane. Using the wrong fuel gas with a tip can lead to flame instability, overheating, or dangerous flashbacks.

Use a standard tip cleaner set. Select the wire size that fits the small flame ports gently. Do not force a large cleaner in, as enlarging the holes can distort the flame pattern.

A popping sound usually indicates a 'starved' flame or a flashback. This happens if the gas flow is too low for the tip size or if the tip is too close to the work, causing it to overheat. Check your regulator settings and cylinder capacity immediately.
