The torch guide encloses a structural metal section to be cut on four sides of that metal section. The cutting torch guide has co-planar top and bottom guiding surfaces and parallel first and second side guiding surfaces. The top and bottom guiding surfaces intersect the first and second side guiding surfaces at four points lying in a same plane. All four guiding surfaces being aligned perpendicular to a longitudinal axis of the structural metal section to be cut, for guiding a cutting torch around the entire structural metal section to be cut. The top and bottom guiding surfaces are adjustable at angle of 90° to 45° from the longitudinal axis, while maintaining the alignment of all four guiding surfaces along a planar cutting plane through the structural metal section to be cut. |
