MT610 - Smith MT610 18-Inch Medium Duty Acetylene Rosebud Heating Tip

Technical Overview of the Smith MT610 Heating Tip

The Smith MT610 is a precision-engineered medium-duty heating tip designed to facilitate high-thermal-energy applications within the oxy-acetylene process. Manufactured by Smith Equipment (a division of Miller Electric), this component is part of the MT Series, specifically developed to provide efficient heat transfer for tasks such as pre-heating, brazing, and metallurgical forming. The tip assembly features a multi-flame head configuration consisting of 12 individual flame ports, drilled to size #57. This array allows for a broad, stable flame pattern that distributes heat evenly across the workpiece, preventing localized overheating while ensuring rapid temperature elevation.

Technically, the MT610 is rated for an average heat output of 128,970 BTU per hour when operating at optimal pressures. The assembly measures 18 inches in overall length, a critical design specification that ensures the mixing chamber and handle remain at a safe distance from the radiant heat of the workpiece. The head is constructed from solid copper, a material chosen for its exceptional thermal conductivity and resistance to deformation under high-temperature cycling. This tip is strictly compatible with Acetylene and Hydrogen fuel gases and is not suitable for alternate fuels such as Propane or Propylene due to injector and mixer design constraints.

Compatibility and Safety Protocols: The MT610 is designed to interface seamlessly with Smith's medium-duty torch handles, specifically the WH100, MW5A, and CW5A models. Operators must adhere to strict gas withdrawal safety protocols. Generating 128,970 BTUs requires a significant volume of acetylene. To prevent the withdrawal of acetone from the cylinder, the withdrawal rate must not exceed 1/7th of the cylinder's capacity per hour. Consequently, manifolding multiple cylinders is frequently required to safely supply the necessary flow rate for this tip. Furthermore, the installation of high-flow flashback arrestors is mandatory to mitigate the risks associated with high-volume gas flow and potential backfires.

This component represents a critical accessory for industrial maintenance, repair, and fabrication environments where controlled, high-intensity heating is a prerequisite for welding preparation or metal manipulation.
