What is a Plunger in Welding?

A plunger is a device that is installed behind the removable seat in a plasma torch head. Its purpose is to enable the safety interlock feature on the torch. Without a plunger, the torch would not be able to sense when the seat is removed, and it would be unsafe to operate.

The plunger itself is a small metal disk with a hole in the center. There is a spring-loaded ball bearing inside the hole. When the seat is in place, the ball bearing sits flush against the disk. But when the seat is removed, the ball bearing pops up, triggering the safety interlock. This prevents the torch from being operated without the proper safety precautions in place.

While the plunger is a small and simple device, it plays an important role in ensuring the safety of those who use plasma torches. Without it, the risk of injury or death would be much higher. So if you’re ever curious about what that little metal disk is for, now you know!

Advantages of using a Plunger in Welding

There are several advantages to using a plunger in welding. First, it helps to ensure that the operator is following all of the safety procedures. This is because the torch will not operate without the seat in place. Second, it prevents accidental ignition of the torch. This can be a serious safety hazard if the torch is not being used properly. Finally, it helps to prolong the life of the torch by preventing wear and tear on the components.

Disadvantages of using a Plunger in Welding

There are a few disadvantages to using a plunger in welding. First, it can be difficult to install the plunger properly. If it is not installed correctly, it may not work properly. Second, the plunger can become damaged over time and may need to be replaced frequently. Third, if the plunger is not working properly, it may cause the torch to malfunction.

How to properly install a plunger in welding?

Installing a plunger in welding is not difficult, but there are a few steps that must be followed. First, make sure that the torch is turned off and cooled down. Next, remove the seat from the torch. Then, locate the hole in the back of the torch head. The plunger will fit into this hole. Finally, insert the plunger into the hole and replace the seat.

What are the main types of welding plungers?

There are two main types of welding plungers: automatic and manual. Automatic plungers are triggered by a sensor that is activated when the seat is removed. Manual plungers require the operator to manually push a button or lever to trigger the safety interlock.
