TYPE79E-4 - Uniweld Type 79E-4 Harris Style #4 Brazing Elbow Tip for UM43 Mixer

Technical Overview of the Uniweld Type 79E-4 Brazing Tip

The Uniweld Type 79E-4 is a specialized brazing and welding tip designed to provide professionals with precision and flexibility in oxy-fuel applications. Engineered as part of the Type 79E series, this tip features a distinct elbow geometry, which is critical for operators working in confined spaces where a straight tip cannot maintain the proper angle of incidence relative to the workpiece. The #4 orifice size is calibrated to deliver a medium heat output, making it highly versatile for a range of material thicknesses commonly encountered in HVAC/R installation, plumbing, and general maintenance repair operations.

Manufactured from high-grade copper, the Type 79E-4 ensures excellent thermal conductivity, preventing the tip from overheating during prolonged use while maintaining a stable flame cone. This specific model is a "Harris Style" replacement, designed to interface seamlessly with the Uniweld UM43 mixer. The compatibility with the UM43 mixer allows this tip to be used on standard 43-series torch handles, providing a modular solution for users who already own Harris-compatible equipment. The threaded connection is precision-machined to ensure a gas-tight seal, minimizing the risk of flashbacks and leaks which are critical safety concerns in oxy-acetylene processes.

The tip is optimized for use with oxy-acetylene fuel gas mixtures, providing the concentrated heat zone required for capillary action in brazing copper pipes or welding mild steel. The elbow design not only aids in physical access but also reduces operator fatigue by allowing for more ergonomic hand positioning during overhead or vertical-up brazing tasks. Whether used for silver soldering refrigeration lines or fusion welding steel brackets, the Type 79E-4 delivers consistent performance and reliability.
