ABSTRACT:
A torch angle measuring device, comprising: (a) a support rigidly clampable to the nozzle of the torch; (b) a reference member; (c) joint means between the reference member and the support providing axes of rotational movement therebetween, the axes being at 90.degree. to each other and each being transverse by 90.degree. to the nozzle axis; and (d) plumb level means on the reference member for displaying levelness in planes parallel to the joint means axes. The joint means has the first of the axes effective to determine lead angle and the second of said axes effective to determine transverse angle. The device additionally includes means for holding the device in an adjusted angle position.
