Abstract: A system for using a cutting torch for making accurate curved, straight and beveled cuts. A supporting and guiding device is attached to cutting torches, which may be of various sizes and shapes, and includes an elongated bar having a ring and opposed set screw clamp at one end to receive the torch tip. A member on the elongated bar carries a workpiece engaging knife-edge wheel and supports the lower parallel tube of the torch, this member being removably mounted on and slidable along the bar to desired positions. The height bar above the wheel is adjustable for positioning the burning tip at the correct angle and spacing with respect to the workpiece. The wheel can be positioned with its plane transverse to the bar for making curved or lateral cuts, or parallel to the bar for making longitudinal straight, perpendicular or bevel cuts. A centering pin is slidably positionable on the bar for making long radius cuts.
