Bernzomatic TS8000: the best torch for copper pipe soldering
The TS8000 is the torch recommended by most professional plumbers for copper pipe work. The piezo ignition eliminates the need for matches in tight spaces and the trigger lock allows consistent flame without hand fatigue during longer soldering sessions. The swirl flame tip heats the entire fitting circumference simultaneously rather than requiring the user to move a pencil flame around the joint - a significant advantage for getting consistent heat across the full solder area. In our comparison, the TS8000 achieved soldering temperature on a 3/4 inch fitting in 12 seconds with MAP-Pro fuel versus 18-22 seconds for competing torches. All 15 joints pressure tested clean at 150 PSI.

Bernzomatic ST500 Basic Torch: the runner-up for occasional use
The Bernzomatic ST500 is the appropriate choice for a homeowner who solders infrequently and does not want to invest in the TS8000's swirl tip premium. It requires a lighter or match to ignite and delivers a standard pencil flame, but the quality of heat output is reliable and adequate for basic residential copper pipe work. For a first-time plumber doing a single bathroom repair, the ST500 at plus a propane cylinder gets the job done. For anyone planning more than occasional use, the TS8000's additional features pay for themselves quickly in improved results and convenience.
Before you buy
Fuel type compatibility
Most quality torches accept both propane and MAP-Pro cylinders, giving you the flexibility to use standard propane for small work and the hotter MAP-Pro for larger diameter pipe. Verify dual-fuel compatibility if this matters to you.
Ignition method
Piezo auto-ignition is a significant convenience upgrade, especially when working in tight spaces where a lighter is difficult to manage with one hand. Manual ignition torches require an external ignition source.
Flame type
Swirl/turbo flame tips heat fittings faster and more evenly than pencil tips. For copper pipe soldering specifically, a swirl tip is the right tool.
Flow control
Trigger-lock flow control maintains consistent flame without requiring constant hand pressure, reducing fatigue during extended soldering sessions and preventing the tendency to throttle back the flame unintentionally.
Cylinder attachment security
Check reviews for any reports of cylinder attachment issues. A torch that does not seat securely on the gas cylinder is a safety risk and should be avoided.
Quick answers
Both propane and MAP-Pro work for soldering residential copper pipe. MAP-Pro burns hotter (2400F vs 1800F for propane) and heats joints faster, which is an advantage for larger diameter pipe (3/4 inch and up). Propane is less expensive and adequate for most 1/2 inch work.
Yes. Copper pipe must be cleaned with emery cloth or a copper cleaning brush to bright metal, then fluxed before soldering. Any oxidation, oil, or moisture on the pipe surface will prevent a proper solder joint.
A pencil flame tip creates a narrow, concentrated flame good for targeted heating. A swirl flame tip creates a broader, rotating flame that heats the entire circumference of a fitting more evenly - better for pipe soldering where the whole joint needs to reach temperature simultaneously.
Touch the solder to the joint (not the flame). When the copper is hot enough, the solder will melt and flow by capillary action into the joint without flame contact. If you must apply the flame to the solder, the joint is not hot enough.
