How To Weld with Propane Torch?

Many people prefer using a propane torch when welding because it makes the welding process simpler, safer, and more efficient. It can be used to weld different kinds of metals. You can see propane torches being used in manufacturing, metalworking, and construction. 

If you don’t know what propane torches are, they are considered air-fuel torches since it requires a mixture of propane gas and oxygen to working for the welding process. This is highly recommended as it can produce a clean-burning flame that can be best used for your heating or welding purposes. Because of this attribute, propane torches are considered affordable and environmentally friendly since they are recyclable. 

Now, we will dig into details on how to properly weld using propane torches. Without further ado, let’s discuss the step-by-step guide.

What are the Steps in Welding with a Propane Torch? A Detailed Guide

First things first: ensure safety. Make sure you perform the welding process in a place where there are no children because propane gas can be very dangerous to them. Then, you need to prepare all the things you need. Wear personal protective equipment and clothing such as safety goggles for eye protection, a welding mask, a welding apron, welding gloves, and Auto-darkening helmets.

Afterward, you can now proceed to the first step of welding with the use of a propane torch.

Step 1: Lighting the Propane Torch

Make sure that you’re already wearing your face shield, thick gloves, and safety goggles first before you even start with anything. First, check if the torch fixture is well-attached to the propane tank. If so, you can now start to turn on the tank’s fuel knob. This will generate a small amount of fuel in the torch’s spark cup.

Now, you can light up the torch with your spark lighter. Keep in mind that you should never use a butane lighter when lighting a propane torch because it is extremely combustible and is not suitable to be placed near a propane gas. In addition, don’t use a plastic lighter too. They can melt easily and will be harmful to the person holding them.

Since certain welding needs the right frame size, you can adjust it. You can make it higher or lower by opening or closing the oxygen valve of the tank. You can tell that you’ve successfully lighted the torch if the flame becomes color blue and if it starts to produce a slight hissing noise. Hence, it’s better to observe it from time to time.

Step 2: Welding With a Propane Torch

Once you’re done lighting the torch, you can now get the materials or metals you will weld.

Start touching the edge of the metal with the right flame and you can notice it melting after seconds. Continue doing this in moderation to get the exact desired result. When you move the flame slowly, the metal you’re welding will be overheated. On the other hand, when you move it too fastly, the metal won’t be heated enough to be welded. 

To join two different metals, put them together then move the flame around. This will create a strong bond between the two.

Step 3: After Welding with a Propane Torch

When you’re done welding, don’t forget to turn off the tank’s fuel knob. Then, store your propane tank in a safe place. 

After all the necessary welding procedures, you can now let the finished weld harden overnight so you can better see the output the next day.

Important Tips for Safety

If you are still confused about how to apply these steps in your welding process, you may look into the user’s manual to know what the specific instructions are. This will greatly help you prevent injuries and damage caused by fire.

To prevent fire, get rid of all the combustible materials in your working area. 

Moreover, do not throw your used propane torch anywhere. Instead, you can bring it to a registered propane recycler. 


Welding with the use of a propane torch is not critical as long as you follow the step-by-step procedures and take note of safety precautions. Using a propane torch is advisable because it is accessible, inexpensive, and environmentally friendly. However, it is not suitable for a large variety of gas welding operations due to its limit in temperature.
