WDW17401 - Miller Smith MAPP/Propylene Pilot Light Assembly

Miller WDW17401 Pilot Light for MAPP and Propylene

The Miller WDW17401 is a specialized Pilot Light assembly designed specifically for oxy-fuel systems utilizing MAPP or Propylene gases. As a genuine OEM component from Miller Electric (often associated with Smith Equipment lines), this part is engineered to meet precise specifications for flow rate and flame stability. In industrial brazing and heating applications where torches are frequently turned off and on, a reliable pilot light is critical for maintaining workflow efficiency and safety.

This assembly is constructed to withstand the thermal stresses common in welding and brazing environments. It provides a steady, low-consumption flame that allows operators to instantly ignite the main torch tip without the need for a striker every time. The WDW17401 is calibrated for the specific density and burn characteristics of MAPP and Propylene, ensuring that the pilot flame does not blow out easily and does not consume excessive fuel when the main torch is idle.

Installation of the WDW17401 should be performed according to the specific equipment manual to ensure a leak-free connection. Using the correct pilot light for your fuel gas is essential; this model is not intended for Acetylene or Natural Gas, as the orifice sizing and mixing dynamics are tailored for MAPP/Propylene. By choosing genuine Miller parts, maintenance teams ensure compatibility and longevity for their heating equipment.
