MW201 - Smith MW201 Acetylene Welding Nozzle 1/32 Inch Slip-In Style

Technical Overview of the Smith MW201 Welding Tip

The Smith Equipment MW201 is a precision-engineered welding tip belonging to the MW200 Series, designed specifically for medium-duty oxy-acetylene applications. This component is characterized by its 1/32-inch welding capacity and its compatibility with Smith's WH100, MW5A, and CW5A torch handles. A defining technical feature of this nozzle is the proprietary "Soft Flame" internal geometry. Unlike standard tips that may produce a harsh, turbulent gas stream, the MW201 is calibrated to deliver a stable, concentrated heat source. This reduction in turbulence is critical for maintaining consistent puddle viscosity and achieving proper root penetration without blowing the molten pool, a common issue in precision welding tasks.

Structurally, the MW201 is manufactured from heavy-wall copper. This material choice is not merely for durability but serves a thermodynamic function; the increased thermal mass allows for superior heat dissipation, keeping the tip cooler during extended duty cycles and reducing the risk of flashback or tip deformation. The tip is bent to a standard 63-1/2 degree angle, optimizing the approach angle for general bench and positional welding.

The connection interface utilizes Smith's "Slip-In" design, which represents a significant deviation from traditional threaded assemblies. The MW201 seats into the torch head using a double O-ring system (replaceable part MW15) to establish a gas-tight seal. This design eliminates the need for wrench tightening, preventing thread galling and allowing for rapid changeovers. The assembly is secured via a hand-tightened nut, ensuring that the tip can be rotated to the desired orientation before locking, providing operational flexibility in restricted access environments.
