1504 - Miller Smith 1504 Replacement Heating Tip Head for ST625/ST628

Miller Smith 1504 Replacement Head for ST625 & ST628 Heating Tips

The Miller Smith 1504 Replacement Head is a critical component for maintaining the performance of your heavy-duty heating equipment. Designed specifically for use with the ST625 and ST628 heating tip assemblies, this replacement head restores the high-output capabilities required for intensive industrial heating applications. Manufactured by Smith Equipment (now under the Miller Electric umbrella), this component ensures that your oxy-fuel setup operates at peak efficiency, delivering the massive heat transfer needed for preheating, straightening, and bending thick metal sections.

One of the defining features of the 1504 head is its optimization for alternative fuels. It is engineered strictly for use with Propane and Natural Gas, making it an economical choice for shops that utilize these readily available fuel sources. When paired with Propane, this head is capable of producing an impressive average output of 455,000 BTUs. For facilities utilizing Natural Gas, it delivers a substantial 313,950 BTUs. This high thermal output is achieved through a specialized fluted flame design, which stabilizes the flame at high flow rates and ensures a broad, even heat distribution pattern that prevents hot spots and promotes uniform soaking of the workpiece.

Replacing a damaged or clogged head is far more cost-effective than purchasing an entire new heating tip assembly. The 1504 screws directly onto the existing tube mix assembly of the ST625 or ST628, allowing for quick field repairs and minimal downtime. Heavy industry professionals rely on this specific head for its durability and resistance to the intense reflected heat generated during operation. Whether you are working in structural steel fabrication, shipbuilding, or heavy equipment repair, ensuring your heating tips are in top condition is vital for safety and productivity.

By utilizing genuine Miller Smith replacement parts, operators guarantee proper gas flow characteristics and safety compliance. The fluted design not only maximizes heat but also aids in noise reduction compared to standard multi-flame tips. This replacement head is a testament to the robust engineering that has made Smith Equipment a leader in oxy-fuel technology. It provides the reliability needed to tackle the toughest heating jobs where deep heat penetration is required in a short amount of time.
