りテ１１い笠の問題点を右していた。Conventionally, fusing and drilling work on the workpiece has been carried out using gas cutting, powder lance, oxygen lance, etc. However, in the case of gas cutting, the cutting torch is easily damaged and the damage to the concrete, structure, etc. However, in the case of a powder lance, powder such as iron powder is continuously fed into the oxy-combustion part, so some of the powder may be scattered around. There was a risk that the oxygen or compressed air used to feed the powder could backfire and cause an explosion. In addition, in the case of an oxygen lance, it is troublesome to replace the lance, and moreover, the lance supply is automatically continuous, which is a problem with the cap.
