Best Soldering Torches for Copper Pipe

Soldering copper pipe is one of the fundamental skills of home plumbing repair. A good propane or MAPP gas torch heats the fitting quickly and evenly, the solder flows into the joint by capillary action, and you have a leak-free connection that will last the life of the house. The torch you choose matters less than technique, but the right tool makes the job faster and safer.

Propane vs MAPP Gas

Propane torches burn at around 3,600 degrees F – plenty of heat for 1/2-inch and 3/4-inch copper pipe. MAPP gas (now typically MAP-Pro) burns hotter (around 5,300 degrees F) and heats fittings faster. For occasional household use, propane is sufficient. For 1-inch and larger pipe, or high-volume professional work, MAP-Pro is worth the extra cost.

Our Top Picks

1. Bernzomatic TS8000 High Intensity Torch

The professional benchmark for copper pipe work. The swirl flame heats fittings faster and more evenly than pencil-flame designs, the trigger ignition is reliable, and the valve holds a steady output. Compatible with both propane and MAP-Pro cylinders.

2. Bernzomatic ST500T Basic Torch

The right starting point for homeowners soldering their first few joints. Pencil flame, simple valve, inexpensive. Slower than the TS8000 but perfectly adequate for 1/2-inch and 3/4-inch work.

3. Lincoln Electric KH990 Soldering Kit

A complete kit with torch, solder, flux, and sandcloth for the first-time DIYer. Nothing premium, but everything you need arrives in one box.

FAQ

Can I solder in a confined space?

Yes, with caution. Use a heat shield behind the fitting to protect the wall. Keep a wet rag handy. Work in a well-ventilated area – flux fumes are irritating. If the space is very tight, SharkBite push-fit fittings eliminate the need to solder entirely.
