SW207 - Smith SW207 SW Series Heavy Duty Acetylene Welding Tip, 3/16 Inch Capacity

Smith SW207 Heavy Duty Acetylene Welding Tip Overview

The Smith SW207 is a premium-grade consumable designed for professional oxy-acetylene welding operations requiring precision and durability. Part of the renowned SW200 Series, this heavy-duty tip is engineered to handle material thicknesses up to 3/16 of an inch (approximately 4.8mm). It is specifically manufactured to interface seamlessly with Smith Equipment's WH200 and SW1B torch handles, as well as legacy SW1 and SW2 models. The tip features a 63.5-degree bend angle, optimized to provide the welder with a comfortable working position and clear visibility of the weld pool during flat and horizontal operations.

Technically, the SW207 distinguishes itself through its swaged construction. Unlike standard drilled tips, the swaged design creates a smooth internal gas path that streamlines the flow of the oxy-acetylene mixture. This results in Smith's proprietary "Soft Flame"—a stable, concentrated heat source with minimal turbulence. This aerodynamic stability is critical for preventing the molten puddle from being blown out or agitated, thereby ensuring consistent bead profile and penetration. The flame characteristics allow for precise heat localization, making it an ideal choice for critical structural welds where heat input management is paramount.

Material selection for the SW207 emphasizes thermal management and longevity. The tip is machined from heavy-wall copper, which provides superior thermal conductivity compared to thin-wall alternatives. This mass allows the tip to dissipate reflected heat more efficiently, allowing for cooler operation even during prolonged welding cycles in confined spaces. The robust copper construction also enables the tip to be refaced; the long straight-away section at the nozzle end permits maintenance personnel to dress the face of the tip if it becomes damaged or fouled, significantly extending the service life of the consumable. Furthermore, the SW207 utilizes Smith's "Slip-In" connection technology, utilizing a double O-ring seal that allows for hand-tightening. This eliminates the need for wrenches, preventing thread damage and reducing changeover time to approximately six seconds.
