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

Heavy-Duty Heating Performance with Miller Smith ST825

The Miller Smith ST825 Heavy-Duty Propylene Heating Tip is an industrial-grade component designed for professionals who require substantial heat output for demanding metalworking tasks. Engineered by Smith Equipment (now under Miller Electric), this heating tip is optimized for use with propylene and propane-based fuel gases, delivering an exceptional 830,000 Average BTU/Hour. This level of thermal energy makes it ideal for preheating heavy plate, bending, straightening, and other high-intensity heating applications where efficiency and speed are paramount.

Advanced Safety and Design

Safety is a core feature of the ST825. It utilizes Miller's renowned in-tip gas mixing technology. By mixing the oxygen and fuel gas within the tip itself rather than in the torch handle or tube, the system isolates any potential sustained backfire to the tip, protecting the operator and the equipment. This design also improves gas flow efficiency. The unit features sturdy stainless steel tubes that provide structural integrity and permit higher gas flow rates compared to standard brass tubes, ensuring consistent performance even under continuous heavy use.

User-Friendly Operation

The ST825 is designed with the operator's convenience in mind. It features a hand-tighten tip seating mechanism, allowing users to change tips quickly and securely without the need for wrenches or tools. This reduces downtime and prevents damage to the seating surfaces from over-tightening. Additionally, the tip assembly includes double O-ring seals that allow the tip to be rotated 360 degrees while seated. This flexibility helps reduce hose drag and operator fatigue during long heating sessions. Compatible with WH200, WH200A, and SW1B torch handles, this tip is a versatile addition to any heavy-duty oxy-fuel setup.
