When something made of plastic breaks, what do you usually do? Well, I used to toss those out and get a new one. It’s pretty evident if the item isn’t so expensive. But, what if it’s something expensive? Like a part of your car? What to do then? Do you still throw it out? You can’t!

Using glue might be a temporary solution, but not the best one. It’s messy, and it doesn’t look good after it dries up. Also, the bond can break away anytime, and you won’t even know it. If the car parts are separated that you glued together, one of them could be coming off while you drive, and you won’t even know it!

This is why plastic welders are necessary. It’s the most cost-effective solution to fix any plastic items around the house, including car parts. It’ll save you time, money, and effort. But, finding the best plastic welder in the market isn’t an easy task.

That’s why, we’ve brought a list of the 10 best welders for plastic and a buying guide to help you out with your purchase.

How To Choose The Best Plastic Welders?

Now that you know about the finest plastic welders available in the market, it’s time for you to make a decision. To choose the best plastic welder, you need to know the factors you have to consider before purchasing.

Type of the Welder

Depending on the purposes, you have to choose the plastic welder with a suitable type of welding. You have the option to select from airless guns, heat guns, LED UV guns, etc.

Airless guns are perfect for creating a thin bond. They come with metal tips that melt the plastic after the tip is hot. It’s not suitable for fixing structural integrity as the bond isn’t thick enough.

Heat guns create hot blasts of air that softens the plastic and creates a strong bond. Most of them come with microprocessors that ensure precise welding. The hot blasts can make the plastic soft, allowing you to fix the structural integrity.

Lastly, you have the UV gun that works with liquid plastic as adhesive. When you put UV light on the liquid plastic, it gets hot and creates a strong bond instantly. You can use these for wooden materials as well, along with plastic items. Also, the hardened adhesive can be polished with sandpaper.

So, each of the plastic welders is suitable for a distinctive type of welding. You have to choose the best one depending on your purpose.

Temperature and Airflow Settings

Plastic welder offers several types of functions. Some of them come with an adjustable setting feature, while some have fixed settings. Which one you should get mainly depends on your need and preference.

But, to make sure you’re getting the most out of your plastic welder, it’s always best to go for the one that comes with an adjustable setting feature. In such devices, you can adjust the temperature and airflow depending on the welding task you’re doing.

Some of them might also come with an LCD panel as an added benefit. With the LCD, you can monitor the adjustments you’re making.


It defines the amount of power your plastic welder can generate. The more wattage it comes with, the more power it can produce. If you’re buying a plastic welder for heavyweight works, you have to go for the 1300W or 1600W plastic welders. 200W plastic welders will be suitable for lightweight to medium range of welding tasks.


Most of the plastic welders don’t weigh much. But, if you’re going to use it for a long welding session, you have to keep the weight in mind. If you choose something too heavy, your hands will go numb after a while, and there’s also a chance of getting less precise welding work.

Moreover, if you need to perform any task outdoors, you’ll have to carry the whole kit with you. So, if the kit weighs a lot, you can’t carry it easily as you want.

Price Range

If you’re on a budget, price is the most significant factor that you have to consider. Even if you’re not, you shouldn’t invest in something that’s not going to serve you properly for a long time. Good quality plastic welders last for years. So, invest in something that’s durable and performs well.

The finest plastic welders will surely cost a bit more than the average ones. But, that doesn’t mean that you’ll have to spend a fortune to buy one. A lot of the excellent plastic welders are available within an affordable price range. Make your pick, and buy the one you need.
