Plastic Welder Buying Guide

Before you start spending on plastic welders, know that essential research can help you get the right product. Otherwise, you will get stuck with a product that does not meet your needs! Here are some of the important factors you need to consider before purchasing a plastic welder.

Heating Type

For common usage, there are two types of models available for plastic welders. First up, we got an airless model. This welder is equipped with a tip made out of metal, and it gets heated and fixes the upper layer of plastic.

Such type of welders is not so good compared to heat guns, and they are only used for filler works. A heat gun emits hot air, and you can control the temperature by yourself. As a result, you can do more sophisticated tasks and make the hardest repairs possible.


The power of a plastic welder is an essential consideration while shopping for one. Usually, the recommended wattage for a plastic welder is around 200 W. Make sure that both the heat emission and airflow remain consistent.


Plastic welding kits should come with necessary attachments that will help you with the welding process. For example, kits for different types of welding (speed, pendulum, and tack welding) are essential. Moreover, plastic rods and other attachments make the process easier. So, always look for plastic welders provided with all the essential attachments.

Temperature Control

Controlling the temperature of a plastic welder is essential for precise work. Usually, professional welders will prefer welding machines with a sophisticated temperature control system.

Along with temperature, controlling the airflow is pretty crucial. A welding machine that allows you to control both the temperature and airflow seems to be excellent for plastic welding. As a result, if you want more control and looking for welders that can do complicated welding, it is better to have something that allows temperature and airflow control.


Speed, pendulum, and tack – these are the three techniques used in plastic welding. Each of the methods requires a unique type of weld. So, not all plastic welder is suitable for every technique. Also, for following a unique technique, you need to use the right attachments.

Hobbyist or Professional

If you are just a hobbyist who wants to repair their own items, you can go for a product that requires a lesser amount of wattage or power. As we have discussed before, not all plastic welders are the same. Some are suitable for stronger bonds, while others are used for everyday tasks.

If you are a hobbyist, you can purchase a welder that has lesser power. You should also go for a welder that is easier to use. Moreover, make sure that you are not getting something too expensive.

When you are a professional welder, you need something more powerful and a high amount of wattage. Usually, the welders you are looking for have microprocessors and temperature gauge. You can easily control the temperature and also do complicated tasks.

Frequently Asked Questions

Is plastic welding stronger than glue?

Plastic welding is significantly better than using glue. Moreover, it is very quick and can be done without spending a lot.

Can you plastic weld PVC?

Almost all kinds of plastics can be welded and it is no different for PVC. Heating a PVC or using a liquid plastic welder on PVC can weld it properly.

How long does plastic welding take?

If you are using liquid plastic welders for fixing smaller pieces, it only takes around 10 seconds to work. However, hot air welders can take more time as it requires time to cool down. It also depends on the thickness of the plastic and what kind of plastic it is.

Final Note

After this, forget about taking anything made out of plastic to repair and spend a large amount of money. Just use a  welding machine for plastic that can easily help you fix it without any additional cost.

Make sure to purchase the right kind of welder because not every tool is suitable for a specific task. As you can see above, not every welder is the same, and they also have dissimilarities on their function.

Whether or not you are a professional or doing this out of a hobby, with the help of the right guide, purchasing a welder wouldn’t be too much of a hassle. Hopefully, this review will allow you to pick the right welder you need!
