the plate assemblies 1 on a welding table 10 separated by a distance lightly larger than the length of a pipe 3 hold one flange 2 next to one s plate 5 turn the oh plate 4 clockwise or counterclockwise about its center 8 using handle 7 to align studs 15 to two screw holes 16 of flange 2 attach flange 2 to studs 15 turn oh plate 4 further counterclockwise to remove any end play between studs 15 and the screw holes 16 and make sure that the center of flange 2 is aligned with center 8 of the oh plate 4 fix the other flange 2 to the other plate assembly 1 in the same manner insert one end of pipe 3 onto one flange 2 and the other end of pipe 3 onto the other flange the position of the plate assemblies on both ends can be adjusted accordingly then the welding job of pipe 3 to flange 2 can be performed on both ends an additional welding table accessory 11 serves as an adjustable height rest mechanism for supporting a substantial portion of a pipe 39 s weight making it easier to properly fit the flanges 2 to the pipe for successful welding the table accessory 11 as shown in fig8 12 is comprised of a base 21 a cylindrical post 23 a cylindrical knob 22 a snap ring 24 locating pins 25 a and 25 b and a screw 26 screw thread is equipped around the top portion of base 21 there are two cylindrical recess areas in the middle of base.
