1. Choose One-Piece or Two-Piece Nozzle:
   Acetylene - one-piece nozzle always.
   Other Fuel Gases - two-piece nozzle provides most efficient operation for normal cutting. One-piece nozzle extends life where heating is very severe.
2. Choose Series:
   OXWELD® 1500 Series Nozzles -
   CW-23, CW-400 and CW-500 Cutting Attachments
   C-32, C-66, C-77 and C-97 Hand Cutting Torches
   All Machine Cutting Torches
   PUROX® 4200 Series Nozzles -
   CW-200, CW-250, and CW-300 Cutting Attachments
   Type “E” and C-84 Hand Cutting Torches
3. Choose Preheat Capacity: Choice of nozzle depends on preheat capacity. Steel coated with rust and scale, as well as bevel cutting, requires heavy preheat.
4. Choose Size:
   Select size recommended for thickness of steel to be cut. Oversize nozzles waste gas. Use oxygen pressure recommended for nozzle.

OXWELD® and PUROX® Cutting Nozzles

• Hard drawn, electrolytic, tough pitch copper used in one-piece nozzles – withstands heat and wear – outlasts any copper alloy nozzle
• One-piece nozzle has triple swaged interior – gas passages are mirror smooth with internal angles rounded for non-turbulent, more efficient gas flow – clean, smooth cuts with minimal kerf
• Preheat ports are closely spaced around cutting orifice for greater concentration of preheat flames
• Long, parallel preheat passages – permit re-dressing nozzle without affecting performance
• One-piece nozzle is a single piece of solid copper – provides maximum cooling – recommended always for acetylene, and for other fuel gases when heat exposure is unusually severe
• Two-piece nozzles – recommended for high efficiency with fuel gases other than acetylene – solid copper, heavy-wall external sleeve and brass internal sections can be ordered separately to minimize replacement cost
• Conical seats – instant aligning provides tight seal, prevents leaks around nozzle nut
