As plastic car parts age, they become brittle and are more prone to cracking. Cracks can also come from accidents, stress and improper use. This leaves us in a position where we have to repair, or replace the cracked part and it is often expensive. Glues can be messy and the end result isn’t always visually appealing. Dried glue smears are unsightly and oftentimes impossible to remove. In addition, glue isn’t always a long term solution, sometimes it just doesn’t hold up well. The best plastic welders offer a quick, easy and long term solution. When done correctly a plastic weld will blend in and hold up indefinitely, making it an effective solution.
There are many plastic welders available in the market and this can leave you with a lot of questions. Which one is the best? Which one will produce the best weld? Which one offers the most use? It can be overwhelming for someone who doesn’t know a lot about plastic welding and just wants to fix their Plastic Car Bumper (for example), instead of replacing it.
That’s why we’ve created this review of the top rated plastic welders and we’ve included a buying guide. We’ve gone over the good and the bad about each one, to make it easier for you to choose the right plastic welder for your needs.

Things to Consider Before Buying the Best Plastic Welder
There are some important things to consider before purchasing a welder. These things are:
1. Amount of Power the Plastic Welder is capable of
The power of plastic welders is measured in wattage. The higher the wattage a plastic welder has, the higher its max heat setting will be. However, in most plastic welders gun, airflow is required to distribute this heat and effectively soften the plastic to form a strong weld.
Too much heat, with poor airflow, will result in the repair taking longer to finish, as well as, burned out heating elements and potential damage to the material being welded. This can also lead to burned plastic and an ineffective weld. Too much airflow can also negatively impact the integrity of your weld as it cools the air temperature.
The best plastic welder will have a narrow and consistent airflow, a temperature range suitable to your plastic type and a visible temperature display in the form of a dial, or display.
2. Welding Type and Tip Compatibility
There are 3 types of plastic welding, these are tack, pendulum, and speed. Each method is used for different types of repairs, or fabrications and will produce a different kind of weld. These methods rely on the application of the device, as well as the movements of the welder. Different tips also produce certain weld styles more effectively than others. Depending on the style of the welder, the tip you need may, or may not be included, or compatible.
Contact welders are less useful in this aspect, as they use a limited selection of tips, that change the shape of the contact point. Heat guns, on the other hand, offer a wider variety of uses and are compatible with a larger selection of tips.
3. The Intended Use of the Plastic Welder
Not all plastic welders will work for every repair job, or project. Professional welders require powerful, high wattage devices, with adjustable heat settings. They need their welders to be able to effectively heat and join industrial plastics while being durable enough for prolonged, frequent use.
In contrast, a hobbyist, or someone only needing to do a few quick repairs would be better suited to a simpler, easier to use the device. They need a plastic welder that is inexpensive but can still finish a job quickly, with the user needing minimal experience.
Therefore the intended use of your plastic welder and your experience in using one directly relates to which plastic welder is best for your needs.
4. The Heating Type
There are 3 styles of plastic welders. The first style is contact welders (airless). These welders use a heated metal tip, much like a soldering iron, to melt the plastic as it touches it. This style is useful for quick welds that require small, precise welds. Welds produced by contact welders are usually only suitable as filler welds and not for structural integrity. This is because they form a thin bond between the two pieces, much like glue, instead of melting the pieces together. These devices are better suited to small projects.
The second style of plastic welders are heat guns, these devices use a blast of hot air to soften the pieces being joined while allowing you to weld them. The softened state allows the pieces to bond with each other, as well as, with the welding material. Which makes for a much stronger bond, suitable for structural repairs. This style of device will produce a durable and long lasting weld. These devices are good for both large and small projects.
The third style of plastic welder uses high frequency, or ultrasonic waves to create heat and melt the plastic. This style of the welder is often only used in factory and laboratory settings and is not readily available to most professionals, or hobbyists.

How to use a Plastic Welder Safely
In order to avoid injury to yourself, or others while using a plastic welder there are some guidelines you should always follow. Plastic welders can reach temperatures well over a thousand degrees. Both the welders and the plastic can easily reach temps that will result in serious injuries, as a side note, some plastics can release noxious fumes while being welded. Plastic welding should be treated with the same precautions that are used when welding metal.
Wear Proper Clothing and Welding Equipment
Anyone operating a plastic welder, or in the area during the welding process should wear the proper attire. This includes, but is not limited to clothing that fits snugly and minimizes exposed skin, to protect against airborne plastic, such as splatters. Gloves rated for hot materials and welding are necessary to prevent burns to your hands. Protective eyewear should be worn to protect your eyes from the heat and any splatters. In addition, a respirator should be worn by all parties to protect against the inhalation of chemicals released during the welding process.
Read the User Manual and Follow instructions
You should always read the user manual before operating any welding device. Not only to understand how the device works, but also so you know if the device is malfunctioning. If you are unsure of something or need clarification, do not hesitate to contact the manufacturer of the device and ask questions.
Have Emergency Procedures in Place
Before using a welding device, familiarize yourself with, or implement safety procedures. This ensures that in the event of an emergency everyone, including yourself will know what to do. This can prevent harm and ensure necessary actions are quickly executed, should an accident occur.
- Maintain a Clean Work Environment
By reducing clutter in your workspace you will not only increase your productivity, but you will also remove potential hazards. Less clutter means you will not bump into, or trip over things while welding. Falling, or knocking things over while welding can result in damaging the project, or severely burning yourself.
- Read the M.S.D Sheets
Many people overlook this critical step, but it is important to always review the M.S.D sheet before welding. These sheets include important information, including a hazardous chemical in the plastic, as well as, details pertaining to fire and explosion hazards and first aid recommendations. If you do not have M.S.D sheets related to the kind of plastic you are welding, they can be obtained from the manufacturer.
How to Use Welder safely (Video Instruction)
In this review, we have discussed the details, pros, and cons of each welder. We have also gone over the important aspects you should consider when purchasing a plastic welder and the general safety guidelines you should follow while operating one. We hope our review and the included information has educated you in your decision on choosing the best plastic welder for your needs.
If you are a professional welder, a stronger, more expensive welding kit will better suit your needs. More expensive welding kits include more materials, as well as better quality welders. A quality welder will ensure your welds are strong, effective and visually appealing while being completed in a timely matter. These devices will also hold up to daily use, over a longer period of time than cheaper options.
If you are a hobbyist or only need to complete a quick, one-time project, a cheaper device is your best option. Cheaper plastic welding kits normally include fewer accessories and materials, as well as, the welders themselves being less powerful. However, if you only intend to use the welder a few times, there is no need to invest in a more expensive device.
Ultimately the best plastic welding kit for you will rely on your personal preference and the intended use of your welder.
