MODEL 138
138 Oxy-Acetylene Cutting Tip · Airco Style
The 138 series is a one-piece oxy-acetylene cutting tip built for Airco / CONCOA style torches. A solid copper body and light-preheat design keep the preheat flame tight and concentrated, which suits hand cutting, machine cutting and fine contour work on clean carbon steel. Eight sizes from 00 to 6 cover cutting-oxygen orifices of 0.8 to 2.4 mm and plate from 1 to 150 mm, so the tip can be matched to the thickness on the job.
- Fits Airco / CONCOA style torch seats

- Light preheat with a concentrated flame for clean, narrow kerfs
- Eight sizes (00–6) cover 1–150 mm plate
