BRANCH JOINT WIPED FLAT
The materials required for this joint do not differ from the preceding one. If the pipe used for the branch joint at a 45° angle is in good shape, it can be used for this joint by simply changing positions. The tools needed will not be any different. The ladle and the wiping cloths, of course will be required. A pair of pliers can be used to advantage in picking up the hot solder. The wiping cloths should receive a little more oil to keep them soft and pliable. Oil the edges of the cloths well.
Supporting.—To support this pipe for wiping have each end rest on a brick. Each end can be weighted to hold it in place.
Wiping.—To wipe this joint, proceed to drop the solder on the joint. When the pipe is thoroughly heated and the solder works freely around the pipe the joint can be wiped. The procedure is like the preceding one. The wiper is cautioned to move the ladle constantly while dropping the solder.
BRANCH HELD VERTICAL
After a number of the previous joints have been wiped successfully, the pipe is placed in such a position that the branch will be vertical. The supporting of the pipe to hold the joint in this position for wiping is very easily done after handling the 5⁄8-in. joint in this position. The following points may be found helpful: The solder is splashed on the joint from the ladle. The top edge of the joint is kept hot by keeping the solder covering it. When the proper heat has been got up, the top edge is wiped first, then the bottom edges both front and back. The body of the joint is wiped last and a cross wipe finishes the joint. I have found that the beginner in many cases, when this joint is reached, tries to wipe it with many short strokes. The habit is a bad one and should be stopped as soon as noticed. Learn to wipe the top edge with only two strokes, the bottom edge with not more than four, the body of the joint with four, and one cross wipe to finish. This joint should be finished as symmetrically as possible and wiped while the solder is hot.
RUN HELD VERTICALLY
When the vertical branch has been conquered and the wiper can get a good joint every time it is tried, the pipe can be changed to a different position. The run is placed in a vertical position and the branch horizontally to the left. The catch pan is put under the end of the pipe. Follow the same directions for supporting this joint as were given under the 5⁄8-in. branch placed in a similar position. The wiping of this joint is so nearly like the preceding branch joints that I will not give any instructions at all. This joint is finished at the same point that the other branch joints are finished. However, there are one or two matters that should be kept in mind. Some of the small matters are often overlooked and should be called to mind occasionally. Do not allow the solder to accumulate in the pan. If the cloths are burned, they should be turned, or new ones made. If the paper has started to come off from the pipe, new paper should be put on at once. Test the solder occasionally and see that it does not get too hot. Upon completion of the joint in this position, the branch joint in its various positions is finished. The beginner has found out while wiping these various joints a number of points that were not mentioned in my description. No amount of detailed description will make a good joint wiper. Patience and practice are as important in joint wiping as good preparation and good solder.
