1499 - Miller Smith 1499 Replacement Head for ST635 Propane Heating Tip

Miller Smith 1499 Replacement Head for ST635 Heating Tip

The Miller Smith 1499 is a specialized replacement head designed exclusively for the Smith Equipment ST635 Heavy Duty Heating Tip. Engineered for industrial environments where high heat input is required, this component is critical for maintaining the performance of your oxy-fuel heating setup. The head is specifically calibrated for use with Oxy/Propane gas mixtures, leveraging the high total heat content of propane to deliver substantial thermal energy to the workpiece. Unlike standard acetylene tips which focus heat in the primary cone, this propane-specific head utilizes a fluted design to stabilize the flame and project heat effectively over a larger surface area.

Technical specifications for the 1499 head indicate a massive thermal output, with an average rating of 614,195 BTUs. This level of heat generation makes it suitable for the most demanding metalworking tasks, including preheating thick plate prior to welding, post-weld heat treating, and large-scale bending or straightening operations. The fluted flame configuration is essential for managing the high volume of gas flow required to achieve this BTU rating, preventing flame blow-off and ensuring consistent combustion even under heavy load.

As a genuine Miller Smith replacement part, the 1499 ensures seamless compatibility with the ST635 mixer and tube assembly. Using OEM replacement parts in oxy-fuel equipment is vital for safety, as it guarantees that gas seating surfaces and thread engagements meet the original manufacturer's strict tolerances. This head allows operators to extend the service life of their existing ST635 heating tips by replacing only the component most subject to thermal wear and slag damage, rather than discarding the entire assembly. It represents a cost-effective solution for maintaining heavy-duty heating equipment in shipyards, structural steel fabrication shops, and heavy equipment repair facilities.
