NE835A - Miller Smith Handi-Heet Air-Acetylene Soldering Kit with B-Tank Regulator

Technical Overview of the Miller Smith NE835A Handi-Heet Outfit

The Miller Smith NE835A Handi-Heet Air/Acetylene Soldering Outfit is a comprehensive solution designed for professionals requiring reliable heat application without the logistical burden of an oxygen cylinder. This system utilizes the venturi effect to draw atmospheric air into the acetylene stream, creating a concentrated soft flame ideal for soldering, heating, and thawing applications. The core of the outfit is the NE180A torch handle, machined from solid brass to withstand the rigors of industrial environments. Unlike composite or plastic handles, the brass construction ensures thermal stability and longevity, while the full-length fluted grip offers superior operator control and comfort during extended use.

A defining feature of the Handi-Heet series is the proprietary slip-in tip interface. This engineering choice eliminates the need for wrenches when changing tips, increasing operational efficiency. The tips seat perfectly by hand, utilizing an O-ring to provide a gas-tight seal while allowing the operator to rotate the tip to any angle. This 360-degree rotation capability is critical for accessing joints in confined spaces often encountered in plumbing and HVAC maintenance. The outfit includes three specific tip sizes—NE180-1 (Light), NE180-2 (Medium), and NE180-3 (Heavy)—enabling the technician to match the heat output to the thermal mass of the workpiece effectively.

Gas regulation is managed by the included 30-15-520 single-stage regulator, specifically calibrated for Acetylene B-Tanks (CGA 520 connection). This regulator maintains consistent delivery pressure, ensuring a stable flame profile even as cylinder pressure fluctuates. The kit is completed with a 12.5-foot Grade R single-line hose equipped with standard "B" size fittings (9/16-18 LH), providing ample reach and safety compliance. All metallic components, including the tips and torch body, feature nickel plating to resist corrosion and reflect radiant heat.
