10 Best Plastic Welders
for September 2023

Plastic welders have been around for a long time, and we've tested dozens of them over the years. Our top choice, the BQI Portable Plastic Welding Kit, has a number of features that make it stand out, including a powerful 50-watt heating engine, a sturdy, comfortable handle, and a built-in light. We also like the BQI's built-in staple remover, which makes it easier to remove staples after welding. The BQI Welding Kit is heavier and bulkier than our top pick, but it's smaller and more comfortable to hold, and it carries a 4-star average rating on Amazon, which is the highest rating we've received by any welder. The BQI's heating engine is more powerful than most competitors', and it also has a couple of built-in features, such as a dial for adjusting the heat level and a cap that blocks the dial when it's not in use. The BQI Welding Kit also relies on staples, which you can pick up at any hardware store, whereas our top pick uses welding wire. (We like welding wire because it lets you weld two pieces together without removing any pieces.) The BQI Welding Kit is a bit more expensive, but it's the best welder we've tested, and it's definitely worth the extra expense.

The Wrdlosy Portable Plastic Welder does exactly what it says it will do and it does it well. The plastic welding process seems quite quick, and the tools, which consist of the welder itself, a stapler, a pliers, and a case, are well designed and work well. The welder is simple to operate and has enough power for plastic welding on bumpers, dashboards, and other parts on cars without melting the plastic. Some of our testers found the process to be a little slow, but if you're repairing plastics that are new or in good condition, it makes little difference. If you're welding onto older, worn plastic, the welding process may take longer. The welder is lightweight, making it easy to transport, and it's small enough to fit easily into a toolbox or suitcase, making it a great tool to take with you on an RV or camping trip.

If you're in the market for a small hot-air gun, the TryE 110V Heat Gun 1500W is a fairly decent value. It is easy to use and powerful enough to weld plastic, though it's a bit underpowered to weld metal. It has a range of 30C to 680C, which is more than enough for most welder jobs. The biggest drawback is that the gun overheats quickly, and it gets hot to the touch after only 15 minutes of use it. The heat gun comes with a 6-foot welding rod, a roller, and an adjustable nozzle. The roller makes it easier to use the hot-air gun, and the adjustable nozzle allows you to adjust the heat for different materials. Overall, the TryE 110V Heat Gun 1500W is a decent hot-air gun for arts and crafts projects, but it's best suited for smaller projects.

The Plastic Welder is a handy tool to have around the house. It's small and compact, so you should have no trouble storing it in any drawer, cabinet, or closet. The hot stapler is easy to operate, and the four different types of staples ensure that you can repair almost any crack or hole. The staples are reusable, so you won't have to buy new ones as often. The Plastic Welder comes with a carry case, so you'll always have it with you whenever you're working on a car. One downside, however, is that the Plastic Welder can only be used on plastic. You can't use it on metal, and the brass stand isn't magnetic, so you can't store it on your dashboard. Also, the staples aren't very sharp, and it can be difficult to pry them out of the crack. Another downside is that it's fairly noisy, and when the staples are heated, they make a high-pitched buzzing sound.

It heats quickly and evenly, and the temperature control dial is easy-to-use. The welds are sturdy, and the heat-resistant plastic handle provides comfort and control. We like the included pencil tip nozzle, which makes it easier to work in tight spaces, and the dual speed nozzles, which allow you to use this tool on a wide range of materials, including metal, plastic, and wood.

The Beyondlife 1600W Plastic Hot Air Welder Heating Gun is the most powerful and most versatile hot glue gun in our test group. It's the most powerful, too, putting out more than 1600 watts of power. This hot glue gun is well suited for both heavy-duty and light duty projects, such as repairing truck curtains and boat seats. It's also versatile enough to work with a wide variety of plastic materials, including PVC and PE. The gun has several different nozzles, so you can heat the plastic to the exact temperature needed, and you can control the heat with a dial on the gun, so you don't have to constantly adjust the temperature on the gun as you're working. The gun is also very handy, with a built-in carry case, and it's powered with a 15-volt DC power adapter. One drawback: The gun isn't very portable, as it weighs 3.5 pounds, so it's best used on a desktop.

The Mxmoonant Handheld Ultrasonic Welder 500W is a very handy and lightweight tool that's perfect for small projects. It's battery-powered, so you won't have to deal with an power cord, and it has a 500-watt output, which is sufficient for most DIY projects. The Mxmoonant Handheld Ultrasonic Welder 500W is best suited for welding plastic, but if you only want to weld fabric or metal, we recommend going with the Mxmoonant Handheld Ultrasonic Welder 200W instead. While the 500W does produce stronger welds, it's more difficult to use, and it's heavier and more expensive. The Mxmoonant Handheld Ultrasonic Welder 500W is also somewhat noisy and vibrates slightly, so it's less comfortable to use on projects where you don't want your hands moving. The Mxmoonant Handheld Ultrasonic Welder 500W is best suited to welding plastic, but if you only want to weld fabric or metal, we recommend going with the Mxmoonant Handheld Ultrasonic Welder 200W instead.

The 3/8-inch tip is best suited for welding thinner metals. The Triac ships with a 30-minute welding cable, a 5-minute welding cable, a 2.5-minute welding cable, and a 1-minute welding cable. The Triac comes with a 120-volt AC power cord, a 6-foot welding cable, and a protective bag. The Triac weighs about 3.5 pounds, and it's relatively lightweight, so it's easy to carry.
