How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 2 of 9
In this video
Using a manual pipe cutter, the pipe is cut at a pre-marked location. The cutter is placed around the pipe and tightened until the cutting wheel makes contact. The tool is rotated around the pipe, and the handle is tightened incrementally (about a half turn per rotation) to slowly deepen the cut. This process is repeated until the pipe is severed, ensuring a clean and straight edge.
Goal: Make a Clean Cut on the Pipe
- Tighten the cutter gradually with each rotation to avoid damaging the cutting wheel and to ensure a smooth cut.

FAQs
What are the most important safety precautions when soldering copper pipes with a propane torch?
Always work in a well-ventilated area to avoid inhaling fumes from the flux and solder. Wear safety glasses and heat-resistant gloves, and keep a fire extinguisher or a bucket of water nearby as a precaution against accidental fires. Ensure no flammable materials are within the K Tool International Self Igniting Propane Torch's reach.
Is lead-free solder mandatory for plumbing, and why is flux so important for a good joint?
Yes, lead-free solder is legally required for plumbing potable water systems in most regions to prevent lead contamination in drinking water. Flux is crucial because it cleans the copper of oxidation and prevents new oxidation during heating, allowing the Oatey Safe Flo Lead-Free Silver Solder to flow properly via capillary action, creating a strong, watertight bond.
My solder isn't flowing into the joint, or it's beading up on the outside. What am I doing wrong?
This usually indicates insufficient or uneven heat. Ensure you are heating the fitting, not just the pipe, and letting the heat transfer until the copper itself is hot enough to melt the Oatey Safe Flo solder on contact, not the torch flame directly. Also, verify that all surfaces were thoroughly cleaned with 3M emery cloth and the HDX 4-in-1 Fitting Brush, and properly coated with Oatey H-20 Lead-Free Water Soluble Solder Flux Paste.
How difficult is soldering copper pipes for a beginner, and how much time should I allocate per joint?
Soldering is a beginner-friendly plumbing skill, but it requires some practice to master the heating technique. With proper preparation and the right tools like the K Tool International Self Igniting Propane Torch, a single joint can typically be soldered and cooled in about 5-10 minutes, not including initial pipe cutting and cleaning.
