A Preliminary Experiment on the Oxy-Arc Cutting

Abstract

The authors have studied fundamental data on oxy-arc cutting, using a cutting rod made of welding rod and an aluminum tube. The results of the investigation are summarized as follows:
1) Oxy-arc cutting is speedier with less oxygen consumption than ordinary oxy-acetylen cutting, provided proper cutting conditions are given
2) In the case of oxy-arc cutting, the nature of cutting is rather different from that of ordinary oxy-acetylene cutting, and it appers more reasonable to call it "Fusion Cutting". However, , ordinary cutting as is obtained from oxy-acetylen cutting can be performed at lower current.
3) As shoun in Fig 7, cutting speed and oxygeq pressure at lower current are converted to opposite characters at higher current.
