What problems should be paid attention to in flame cutting of steel plate cutting?

In flame cutting, what can be divided into cutting? What are the main tools used?

In flame cutting, the cutting can be generally divided into two types, specifically:
Cutting torch: it is generally operated manually, and the mixed gas used is mainly oxygen acetylene, with acetylene pressure of 0.01-0.12MPa and oxygen pressure of 0.5-1MPa. Its application is mainly used for supplementary cutting.
Cutting machine: it mainly includes cutting torch, sizing mechanism and cutting seam cleaning device, among which the sizing mechanism includes mechanical, pulse and photoelectric, which can realize automatic sizing. It can be used to cut steel plate and tube blank.

The main tool of flame cutting is the cutting torch, which is divided into manual and machine. The latter is used in the cutting machine, but no matter which one is, there are two types: injection type and equal pressure type.
