ST625 - Miller Smith ST625 Heavy Duty Propane & Natural Gas Heating Tip Assembly

Miller Smith ST625 Heavy Duty Propane & Natural Gas Heating Tip

The Miller Smith ST625 is a premier solution for industrial professionals requiring high-performance heating capabilities without the high cost of acetylene. Designed as a heavy-duty heating tip assembly, the ST625 is engineered to function exclusively with alternate fuel gases, specifically Propane and Natural Gas. This unit is a complete assembly that includes both the nozzle and the tip, providing a seamless integration into your existing heavy-duty oxy-fuel setup. It is specifically calibrated to work with Miller Smith torch handles, including the WH200 and SW1B models, ensuring a secure fit and optimal gas flow.

Performance is the hallmark of the ST625. When utilizing Propane, this heating tip is capable of generating an impressive average of 455,000 BTU per hour. For facilities utilizing Natural Gas, the tip still delivers a substantial 313,950 BTU per hour. This massive heat output makes it an indispensable tool for preheating heavy steel plates, large castings, and structural members prior to welding. The tip features a fluted flame design which stabilizes the flame at high output levels, preventing the flame from blowing out even under aggressive heating conditions.

Safety and ergonomics are critical in heavy heating applications. The ST625 boasts an overall length of 31-1/2 inches. This extended reach is a vital safety feature, keeping the operator's hands and body at a safer distance from the intense radiant heat generated during operation. Due to the high volume of gas required to produce this level of heat, it is mandatory to use this tip in conjunction with high-flow flashback arrestors. Standard arrestors may restrict flow too significantly, leading to starvation and potential safety hazards. Additionally, users must ensure their fuel supply is adequate; continuous use requires manifolding 2-3 fuel cylinders or utilizing a 100lb propane tank to prevent tank freeze-up.
