Miller Smith ST825 Heavy-Duty Propylene Heating Tip 830,000 BTU

Miller ST825 Propylene Heating Tip: Power and Precision

Maximize your oxy-fuel heating capabilities with the Miller ST825 Heavy-Duty Propylene Heating Tip. Designed to tackle the toughest industrial heating jobs, this tip produces a massive 830,000 BTU/hr output using propylene or propane-based fuels. Whether you are working in shipbuilding, railcar repair, heavy fabrication, or pipeline construction, the ST825 provides the concentrated, high-volume heat needed to bring thick metals to temperature quickly and efficiently. Its 16-inch length allows operators to maintain a safe distance from the heat source while directing the flame with precision.

Rugged Construction for Industrial Environments

Built to withstand harsh work environments, the ST825 features a composite construction of high-quality materials. The tip end is crafted from copper to withstand intense reflected heat, while the tubes are made from stainless steel to resist bending and corrosion. The base utilizes nickel-plated brass for a secure, long-lasting connection. This robust design ensures that the tip maintains its shape and flow characteristics over time, providing reliable performance shift after shift.

Efficiency and Compatibility

The Miller ST825 is engineered for seamless integration with Miller and Smith heavy-duty torch handles, specifically the WH200, WH200A, and SW1B models. One of its standout features is the "Graf-Tite" soft seat material and hand-tighten design, which ensures a leak-proof seal without the need for tools. This feature not only speeds up tip changes but also extends the life of the torch head by eliminating thread wear. The in-tip mixing design further enhances efficiency by optimizing the fuel/oxygen ratio right at the point of combustion. Note: Due to the high volume of gas flow, heating tips like the ST825 must be used in conjunction with high-flow flashback arrestors and appropriate regulator settings to compensate for flow restrictions.
