ST615 Heating Tip for WH200A Torch Series

The Miller-Smith Equipment ST615 is a 15.75 in heating tip built for the WH200A torch series and ST600 tip series. It uses a tube-and-head design and accepts natural gas, propane or propylene as fuel sources for heating applications.

Multi-Flame Output Across Three Fuel Types

Switching fuel changes the delivered heat: natural gas provides 155,145 BtuH, propane raises output to 244,000 BtuH, and propylene reaches 280,000 BtuH. The multi-flame pattern distributes heat evenly over the work area without needing separate tips.

Suited for High-Capacity Heating

Welders using Smith SW1, SW1A, SW1B, WH200 or WH200A torches can mount this tip directly. Operators needing lower heat output, different thread patterns, or tips for cutting rather than heating should select another model.

Questions about this item

How often will the ST615 tip tube or head need replacement under normal heating work?

The ST615 uses a tube-and-head design built for heating; replace the tip when the head shows erosion or the tube cracks from thermal cycling.

Which output limit is reached first when running the tip continuously on propane?

At 244,000 BtuH on propane the tip reaches its rated heating capacity before gas flow or torch duty cycle becomes the bottleneck.

How much heat and noise does the multi-flame head produce during an all-day shift?

The multi-flame head delivers up to 280,000 BtuH on propylene with a broad, quiet flame pattern; the torch body stays warm but not extreme.
