It is best to start a weld as far to one side as possible so that it can be made with as few interruptions as
possible if a complete circumferential weld cannot be made.
High-speed hand welding with round rod
The step-by-step procedure for high-speed hand welding of rigid PVC with round rod is as follows:
1. Obtain a flat piece of PVC, preferably 18 to 24 inches long, two inches wide, and at least 3/32 inch
thick, and clamp it to the work bench or table.
2. Select the high-speed tool designed for use with the diameter of welding rod to he used. The cold rod
should fit the tool loosely. Prepare the rod by cutting one end at a 600 angle.
3. Conned the welder to a source of either compressed air or inert gas. Turn on air to desired pressure.
Connect electricity (115 volts A.C.) and allow the unit to warm up.
4. Hold the welder upright in the hand, as illustrated.
5. Hold the shoe of the high-speed tool about one-half to three-quarters of an inch above the surface of
the work piece, and hold it at the starting point until the material starts to soften.
