Cut Pipe to Length
Part of project
How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 2 of 9
In this video
The process begins by cutting the metal pipe to the required length. A manual pipe cutter is placed on the pipe. The handle is turned to tighten the cutting wheel against the pipe, and the entire tool is rotated around the pipe's circumference. This process of tightening and rotating is repeated until the pipe is cleanly severed. After the cut, the manual cutter is removed from the pipe.
Goal: Prepare pipe for threading
- For a clean thread start, it is recommended to deburr the inside and outside edges of the cut pipe using a deburring tool or file.
Used in this video
- Manual Pipe Cutter (Pipe Cutter Type: Manual pipe cutter) — Cutting the metal pipe to the correct length.
- Metal Pipe (Material: Metal) — The workpiece being threaded.
- Gloves (Insulation Type: Insulated) — Protecting hands from sharp edges and tool operation.

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.
