What is a Welding Trolley?

A welding trolley is a type of welding equipment that you use to help in the automation of your cutting, welding, and other types of operations.

What is a Welding Carriage_ Image of a welding trolley

The “trolley” part utilizes magnet so that it can clamp and hold onto the job, making it versatile and flexible across a wide array of business industries.

In simpler terms, they’re machines you can use to help you with whatever type of welding procedure you want and need!

Welding Trolley vs. Welder Operator 

A lot of people, even those that have little experience in welding misunderstand these two (2) terms.

Welding Carriage vs. Welder Operator Image of what a welder operator is

A welding trolley is a type of equipment you use to help and assist in the automation of welding. Welder operators, on the other hand, are people who operate on the controls of the device like its adaptive controls, movement, programs, etc.

Welder operators and welders are two (2) different types of people, too. We know what the former is – and the latter simply is the person who conducts and performs the act of welding.

What is a Portable Welder Generator?

For you to understand what a portable welder generator is, it’s imperative that you know what this particular machinery or equipment is first.

What is a Portable Welder Generator_ Sample image of what a portable welder generator looks like

A welder generator, for the benefit of everyone, is a type of machine that is the source of power for welding. It’s a good substitute or alternative for main electricity, as you’ll often use it in sites and locations that don’t have near electrical outlets.

Therefore, we can easily come to the conclusion that a portable welder generator is a machine or equipment that you can use as the source of power for your welding equipment, which is far from what a welding carriage is.

What is a Welding Oscillator?

Welding oscillators, more commonly referred to as welding weavers, are machines or technologies that you use to help in the controlling of the arc heat that’s produced by the weld.

What is a Welding Oscillator_ Image of what a welding oscillator looks like

You use it so that the welding head can move back and forth or sideways, depending on the perspective you are in.

And to answer one of the most frequent questions asked, no, a welding carriage isn’t a welding oscillator. As a matter of fact, the two (2) can complement each other depending on your project or your welding requirement!

There are welding carriages that have welding oscillators for better and more useful operations!

When Do You Need to Use a Welding Trolley?

When Do You Need to Use a Welding Carriage_ Welding trolley being used for automated welding

It’s not necessarily a “need” if you think about it. However, using a welding carriage can give you the assistance you’ve been looking for, especially if you want your results to be precise, accurate, while it’s being done without inducing too much fatigue and stress on your welder.

You can think of a welding trolley to be a type of machine that will help you reach the goals of your projects.

Benefits of Using a Welding Trolley

Why do you think businesses love using welding trolleys? It’s because of the advantages and the benefits that they promise to welders!

Benefits of Using a Welding Carriage Freehand welding – one of the many benefits of welding trolleys

To name a few of the beneficial and advantageous things you can get with it, here they are:

Heightens and Improves Productivity

Welding carriages can help welders be free from fatigue and numbness by maintaining a specific position.

Therefore, it’s easy for us to come to the conclusion that welding carriages can absolutely improve and develop overall productivity without sacrificing the quality and the aesthetics of the weld.


Imagine a manual long weld to be done and completed by a professional welder. While it’s going to be good, it can shave off a lot of time since the welder would have to make sure that it’s precise.

With a welding carriage, on the other hand, it can be programmed so that it’ll move according to how you programmed it. This eliminates the need for a welder to spend time welding it even in complex positions.

Accuracy and Precision

With a welding carriage, the welder can stay in a consistent and a constant position while welding. In long welds, especially if done manually, the welder would have to stop, pause, and reposition himself to make sure that the weld will be accurate.

But, if there’s a welding carriage, it can be done in a straight, single time without the need for the welder to pause and to stop.

These are just some of the benefits and the advantages of utilizing welding carriages in general. Depending on how you’ll use it, you can find a ton of other benefits and advantages to them, too!

What Are Programmable Welding Trolleys?

Programmable welding trolleys are welding carriages that you can program for them to be automated. More often than not, these are the welding trolleys that you can use for high-quality and consistent welds.

Here with us at Waldun, we provide a ton of automated and programmable welding carriages that you wouldn’t be able to find in regular businesses and companies. We will get to that a little bit later.
