Structural ironworker uses heat from acetylene torch to melt and cut temporary steel bolt to remove it and replace it with another bolt, following enlarging lower bolt hole so upper column section can be bolted to splice plate. Torch is fed acetylene and oxygen through hoses from acetylene and oxygen compressed gas tanks. Photo shows the gas control lever in the left hand of the ironworker.
