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

Smith ST625 High-Output Heating Tip for Propane and Natural Gas

Maximize your heating efficiency and minimize fuel costs with the Miller Smith ST625 Heating Tip. This heavy-duty accessory is designed for fabricators, welders, and MRO professionals who need to generate significant heat for bending, straightening, shrinking, and preheating applications. By optimizing the combustion of Propane or Natural Gas with Oxygen, the ST625 provides a cost-effective alternative to acetylene heating heads, allowing for longer soak times and larger heat zones without breaking the budget.

The ST625 is built for heavy industrial environments. It features a robust construction that withstands the rigors of daily shop use. With a length of 31.5 inches, it provides excellent reach, allowing you to apply heat to large workpieces while maintaining a comfortable working posture. The tip is compatible with Smith Equipment's heavy-duty torch handles, specifically the WH200 and SW1B. Its medium-pressure design ensures consistent performance, but operators should be aware of the high flow requirements. To achieve the rated 455,000 BTU (Propane) or 314,000 BTU (Natural Gas), adequate gas supply is non-negotiable. Small 20lb propane tanks are insufficient for continuous use; a 100lb tank or a manifold system is required to maintain the necessary vaporization rate at 70 degrees Fahrenheit.

Key Operational Notes:

• Gas Compatibility: Strictly for use with Propane or Natural Gas. Do not use with Acetylene.
• Safety Equipment: Must be used with high-flow flashback arrestors. Standard arrestors may cause flow restrictions that necessitate increasing outlet pressures.
• Applications: Ideal for preheating weldments, forming heavy metal parts, and stress-relieving large components.

Invest in the ST625 to bring superior heating power to your oxy-fuel kit, backed by the quality and reliability of the Miller Smith brand.
