Can You Solder Copper With A Butane Torch?

  • Take a close look at a butane flashlight when you’re out buying. Is it primarily made of plastic, with only a few metal components? If that’s the case, despite the wonderful price, put it back on the shelf. Torches that have been left on for a lengthy period of time (during the soldering process) get extremely hot. The heat is concentrated around the torch’s top and torch head. If you use too much plastic, your torch head may melt slightly. This will impede the supply of butane to the torch tip, making it impossible to light the torch. Metal-based torches can be used for long periods of time without causing damage.
  • There are six requirements for a successful set-up: These are the six things I can’t live without. My tiny torch (in this case, the Max Flame), a quench cup, soldering tweezers, safety glasses, and a jellyroll pan as a heat-resistant protecting surface. Next to my workshop, I also have a fire extinguisher. It’s always better to be safe than sorry. Knock on wood, I’ve never had to use it, but safety comes first.
  • If a butane micro torch isn’t filled with fuel, it’s useless. For refills, I use normal butane gasoline from the hardware store. Even if you believe it is better to use “To keep your torch head clean, use “triple-refined” gasoline. I use standard, off-the-shelf fuel, and my torches operate well. This is not a recommendation; rather, it is based on my personal experience.
  • I always have my window open when I light my lamp for optimal airflow. Butane is a clean-burning fuel with a relatively short burn period for soldering. What you’re heating, in my opinion, is the biggest source of potentially dangerous emissions. There are certain vapors produced by melting solder and heating flux and metal. The vapors will be kept to a minimum if you work in a well-ventilated environment. For further precaution, you can always use a respirator and a carbon monoxide detector.
  • To protect your table, you’ll need a fireproof work surface, such as a sheet of metal or huge ceramic tiles. Then you’ll need a Solderite board or a charcoal block for soldering. I placed my charcoal block in an annealing pan loaded with pumice for added protection.
  • You don’t need solder when working with tiny silver wire since it fuses to itself. You’ll need flux and solder if you’re soldering sterling or copper. Flux is a paste that keeps the heat where you want it while still allowing the solder to flow. To avoid ruining my good tools, I use pliers, tweezers, and picks only for flame work.
  • Before each usage, refuel the torch to ensure the hottest flame possible. This can also prevent your torch from running out of fuel in the middle of a task–for example, right as your solder is ready to flow!
  • When scraps of silver are burned with a tiny flame, they almost instantaneously convert into perfectly round silver balls. Silver accent balls can be made in practically any size to add to your wire or metalwork jewelry creations.
  • The most basic rule of soldering is that the entire component, not just the connection, must be heated (the place where the two metal ends meet). Concentrating solely on the junction results in the metal being burned away. Instead, swirl the torch around the entire piece slowly and carefully until it’s all very hot. Then concentrate on the joint to make the solder flow (or fuse the fine silver), then quickly extinguish the flame.
  • Because butane torches don’t get much hotter than 2500 degrees Fahrenheit, the amount of heavy gauge sheet and wire you can use, as well as the size of your items, are limited in micro torch jewelry production. Larger components necessitate a greater amount of heat. However, if you want to broaden your skills and make bezels for cabochons or resin, micro torch jewelry manufacturing is a great place to start.
  • Keep the joints or seams all facing the same way when soldering or fusing many parts on a block at the same time so you have a convenient point of reference for where to aim the heat.
  • In comparison to the bright shine you started with, fine silver will appear more white when it’s almost ready to fuse. Focus the heat on the join until it appears whitish or powdery, and it will fuse. Remove the heat as soon as you see the seam join to avoid melting the silver.
  • Cassie shows what happens when you apply too much heat after you’ve fused your join.
  • She explains what happens if you don’t start with a good join before turning on the heat (top right ring). These are all excellent teaching examples that may be used in the classroom “What not to do,” but also to show that life goes on even if something bad happens to you.
  • So you don’t spoil your good tools, dedicate some cheap pliers to your flamework.

What kind of a torch Do I need to solder copper pipe?

A propane or MAPP gas torch can be used to solder copper (methylacetylene-propadiene propane). A yellow tank holds MAPP gas, while a blue tank has propane. MAPP gas is normally a little more expensive than propane, but it heats the pipe considerably faster. Propane works OK, but it takes longer—which could be advantageous if you’re new to soldering copper and working with 3/4-inch or 1/2-inch piping. The torch you choose is entirely up to you.

Can I use butane to solder copper pipe?

A butane torch is an essential item to have on hand, whether you’re searing the perfect crust on a rump roast or brazing a copper pipe fitting in a bathroom remodel. A butane torch produces a flame with a maximum temperature of around 2,500 degrees Fahrenheit. These high temperatures, along with the long flames of butane, which may reach up to 6 inches in length, allow these torches to melt and solder metals such as copper and silver. Butane torches are compact and easy to wield, despite their ability to generate a bright blaze. They are normally under 2 pounds and just about 10 inches long.

If you’re in the market for one of these useful tools, keep reading to find out what qualities to look for when shopping. Also, don’t miss this roundup of the greatest butane torches available.

Is a butane torch hot enough to silver solder?

If you’ve never heard of silver solder before, you might suppose it’s just a specific solder for working with silver. But there’s a lot more to it. It’s one of the most useful home repair supplies you may have. Why? Because it can fix a wide range of metals, including iron, steel, brass, stainless steel, cooper, and, of course, silver. It’s also because it’s really easy to use.

After all, it is a silver alloy, so it is not inexpensive. However, once you have it, you’ll be able to repair items that you would ordinarily discard or take to a welding shop. As a result, the silver solder is likely to pay for itself in a short period of time.

My lawnmower’s throttle lever, for example, broke last summer. I mended it in five minutes and saved myself the cost of a new one, as well as the hassle of ordering and waiting for it to come. When the handle on our saucepan came off, I quickly replaced it. When a visitor’s glasses wire frames snapped, I got him seeing clearly again in the blink of an eye.

Silver solder is available at some hardware stores, however it is usually the low-temperature variety with a tensile strength of around 10,000 psi. Silver solders with a tensile strength of over 60,000 psi are a little more difficult to come by. A welding supply shop may have some, but a mailorder house is the most convenient option. Five feet of 1/16th-inch wire costs around $8 at The Brookstone Co., 125 Vose Farm Rd., Petersborough, N.H., 03458. Make sure you have some flux on hand, and make sure it’s designed for use with silver solder.

A standard household propane or butane torch can suffice, but one of the new MAPP gas-burning torches is preferable. They’re available at most hardware stores. They burn far hotter than regular torches, allowing for faster and easier silver soldering.

Use silver solder in the same way you would regular solder. Parts that will be linked should fit snugly together; you may need to bend or file the parts slightly to achieve this.

Cleanliness is also vital. Wash the pieces to be bonded before lightly sanding or steel wooling the mating surfaces to reveal shiny, bare metal. Don’t touch the surfaces once they’ve been cleaned. Apply a small coat of flux to both surfaces next. Place the parts snugly together and use a clamp or another method to keep them in contact. The joint will fail if the pieces move during soldering.

Apply heat to the area where the work is being done. If one portion is significantly larger than the other, direct the majority of the heat to the larger part; otherwise, the smaller part will heat up considerably faster. Keep an eye on the flux as you apply the torch. At first, the pasty white flux will bubble, then clear up and resemble molten glass. It will then start to flow and stretch out. When that happens, use the hand that isn’t holding the torch to attach the silver solder wire to the job. The solder should be melted now that the job is hot enough. If this is not the case, remove the solder and heat the job for a few more seconds. Reapply the solder after that.

It’s critical that the solder is melted by the work rather than by a direct flame. This ensures that the solder penetrates the parts being joined, resulting in the strongest bond possible. Another tip: silver solder, like regular lead/tin solder, flows toward heat. As a result, you can lead the molten solder wherever you like, even uphill. Simply point the torch in the direction you want the solder to flow.

Remove the solder wire and torch once the solder has flowed into all portions of the junction and allow to cool. Do not touch the work again until the solder has completely solidified. Remove any remaining glasslike flux with a chipper, and the operation is finished.

Can butane braze copper?

Is it possible to weld with a butane torch? No, butane torches do not provide enough heat or energy to effectively braze or weld metals.

The metal will not be affected by a butane blowtorch since it does not get hot enough. It’s important to remember that a blowtorch loses 90% of its heat through contact with the air, making it one of the least efficient welding processes without a shield.

What is the best solder for copper pipe?

Copper pipe is soldered with what type of solder? Copper pipes carrying drinking water should be soldered with lead-free solder. It won’t include any contaminants that you don’t want in your drinking water. It will, however, necessitate a greater melting temperature than a 50/50 solder.

What is the best way to melt copper?

You won’t need an industrial induction furnace to melt copper at home, as you’ll be thrilled to learn. If you’re only melting a small bit of copper, a blowtorch or a cooktop will suffice. It can be melted down into ingots for storage or used for home crafts. Copper conducts heat and electricity quickly, therefore attempting to melt copper at home should be done with caution.

Can you use a soldering iron on copper pipe?

Soldering copper pipe necessitates the use of specific tools. Safety equipment, in addition to your supplies, is required. Because soldering emits fumes, it’s important to keep ventilation in mind.

  • Soldering Torch: Also known as a soldering iron, a propane torch is used for this project. It could possibly be a MAPP torch, which uses a hotter gas than propane to burn.
  • Deburring Tool: This tool is used to remove small jagged and uneven pieces of metal from pipes and fittings. In a pinch, a metal file will suffice.
  • Wire Brush: For cleaning the inside of your pipe fittings, you’ll need this small wire brush.
  • Cut your pipe to size with a pipe cutter. A deburring tool is frequently included with a pipe cutter.
  • Emery tape, also known as plumber’s tape or emery cloth, is a type of tape that is used to polish surfaces. The abrasive surface of plumber’s tape is similar to that of cloth sandpaper. It’s designed to soften rough pipe edges.
  • Steel Wool is sometimes offered as an alternative to emery tape. This isn’t the best way to deburr your pipes. It could leave microscopic metal splinters behind, which could disrupt your soldered bond. If you can’t find emery cloth, use a scouring pad.
  • Pipe Fittings: Select copper fittings that are compatible with your pipe. Before you start soldering, make sure they fit. If you’re going to use the press-connect approach, make sure you have press fittings on hand.
  • Copper Pipe: You’ll need a short stretch of copper pipe to make a repair. Otherwise, you’ll be working with existing copper pipes that require a soldered-on fitting.
  • Solder, often known as soldering wire, is the liquid that melts and flows between two sections of copper pipe to form a junction. It’s packaged on a spool.
  • Soldering paste is often referred to as flux. It acts as a flame retardant for the pipe fitting.
  • Using a rag, wipe away any excess flux. Also, any water that has seeped from the pipes should be dried up. To soak up surplus droplets, plumbers occasionally use a piece of white bread.
  • Wear a respirator if you’re particularly sensitive to scents or smoke. Also, work in a well-ventilated area.
  • Protective Safety Glasses: Protect your eyes from any flying sparks or solder shards.
  • Gloves for soldering: Heat-resistant soldering gloves are ideal. They’re a little more flexible than welding gloves, but they still keep your hands safe from the flame.
  • Heat Shield: This fireproof cloth, often known as a burn blanket or torch blanket, is a must-have. It protects neighboring flammable walls, floors, and other items.
  • Fire Extinguisher: Keep a fire extinguisher nearby in case of an emergency. Make sure it’s full and pressured.
  • Soldering Iron Stand: For the hot iron, you’ll need a stand. If your torch didn’t come with one, make sure you have a non-flammable place to set the iron down.

It’s almost time to get started now that you’ve gathered your resources. You are free to begin your repair right away. It is recommended, however, that you practice soldering with extra fittings and tubing first.

Getting a good bond may take numerous attempts. Work on your actual copper pipe project once you’ve gained confidence and experience.
