The pressure of acetylene in welding torch for oxy-acetylene welding is maintained at _________

The pressure of acetylene in welding torch for oxy-acetylene welding is maintained at _________ Correct Answer 0.66-1.0 bar

The oxy-acetylene system is employed depending on the manner in which acetylene is supplied for welding. In the high-pressure system, the pressure of acetylene at the welding torch is 0.66-1.0 bar and it is 0.1-3.5 bar for oxygen. The low-pressure system pressure for oxygen should be 0.5-3.0 bar.
