ST625 heating tip for high-output heating

This Miller-Smith Equipment ST625 heating tip delivers up to 455,000 BTU per hour on propane and 313,950 BTU per hour on natural gas. It belongs to the ST600 tip series and fits WH200A torch models including SW1, SW1A, SW1B, WH200 and WH200A. The multi-flame tube-and-head design is built for industrial heating applications.

Suited for propane or natural gas heating jobs

Welders and maintenance crews needing a single tip that handles both fuel types at high output will find this model practical. It is not intended for cutting, brazing or fine-detail work, and it will not fit torches outside the WH200A series. Buyers who need lower heat ranges or different tip geometries should look elsewhere.

Threads onto compatible WH200A torches

Installation consists of threading the tip onto a listed torch model and verifying the fuel supply matches the chosen rating. The most common issue is using an unlisted torch or mismatching the fuel type, which can produce unstable flames or insufficient heat. Always confirm the torch part number before fitting.
