Possible Solutions To Weller 7200 Not Getting Hot Issue

Do you ever feel like your soldering guns like the Weller 7200 not getting hot for a while? And for this, we have to start from the very core of the weller solder guns. 

What are the Weller and soldering guns mainly? Weller soldering gun is mainly a heat-producing kit that helps to join metal surfaces. The structure of this soldering gun makes it look like an actual pistol. 

You have to hold the gun between metal surfaces for seconds to heat them and sync afterward properly. There are always some quick fixes available out there if you seek help properly.

This guide also serves the same cause and will explain in a detailed manner to fix Weller 7200 soldering guns. Let’s start right away with why such situations occur, shall we? 

Reasons Behind Weller 7200 Malfunctions

Reasons Behind Weller 7200 Malfunctions

The first and foremost thing, knowing why such heat-up fails occurs. As we acknowledge the reasons behind such malfunctions, things will become much easier. 

So why such failed attempts occur while using The Weller 7200? 

The main reason is often included with wiring and connections. If your wiring is not correctly done or anything with connecting wire, it won’t heat up. 

Structure body low voltage interferes with iron’s high voltage, and as a clash, they both stop working. Sometimes It can also be a bad connection with the tip. 

As ironic as it may sound, the better 7200 gun is one of the lowest watt powers out there. Yet, the problem occurs many times with the gun. 

That is why while giving you in-depth knowledge and ideas on curing Weller 7200’s malfunctions, we will ensure your safety measures first. 

Sounds spooky yet exciting at the same time, right?

Before We Start

Troubleshoot 1 –

The first and foremost issue that often arises with most other soldering guns is the weak wiring setup. What to do? 

  1. First and foremost step, plug in the gun. 
  2. Check the temperature if it’s below average. 
  3. Finally, try plugging in other slots to ensure and confirm that the problem is with the wire

Right after you find the issue, it’s the part we fix it. 

Solution 1 – 

The problem is with the wiring. Therefore, you need to bring change to the wiring set. That way, it will ensure that bolt surveys properly again. All we have to do is – 

  1. Firstly, Take a scissor on hand
  2. After that, cut near the two rear ends to expose the vital wires
  3. Entangle both the wires you find together
  4. Therefore, get a wire barrier and cover it up 
  5. Lastly. try switching the button on and see the magic 

That’s how the wire problem solves easily with a few basic ingredients. But what would happen if the trouble-causing material is the tip head of the gun? 

Troubleshoot 2 –

Now let’s focus on the head part of this gun. Frequently the issue is caused because the headgear is not properly fixed or adjunct with the gun. 

  1. The first step is by turning the plug on 
  2. Notice if the whole gun is working.
  3. Touch the head part on the surface to see if the rod is heating up. 
  4. At last, confirm if the problem is with rods

After confirming the problem comes the solution part. In many cases, it happens due to tip adjustment.

Solution 2 –

The process and simple, yet make sure you wear gloves for this one. 

  1. At first, Turn the plug off
  2. Then, with gloves on, pull the rod part to take it off. 
  3. Addition to the previous step, If the rod part is not coming out, use a wrench to loosen it. 
  4. After loosening it, use the wrench to tighten it again. 
  5. Lastly, turn the plug on. As a result, you’ll be happy to see it work. 

Troubleshoot 3 –

Is the trigger malfunctioning? Sometimes the trigger does mess up and result in troubling the whole soldering gun progress. Giving off wrong signals as well. 

  1. Turn the plugin 
  2. Press the trigger button
  3. See if the wire is properly fixed
  4. Check the heat detector as well to check it’s all good. 
  5. Finally, confirm it’s the trigger button malfunctioning. 

Solution 3 –

The first and foremost thing to keep in mind is that the solution is a bit lengthy. Therefore, it is worth the effort you give in it. Here is how to solve such cases

  5. If it is loose, use flux to make it tightly attached. 
  6. Likewise, check if it is not attached properly and keep the strings inside together and add extra plastic or paper. 
  7. Now you are all set, so make up the gun again. 
  8. Lastly, do the plugin and shoot to see if the trigger is working now. 

These are all the possible issues that may arise while working with a soldering gun, especially Weller 7200.
