Best Plastic Welders 2021

Welding plastics seems like an uncommon thing, but plastics too can be welded. If you are looking to purchase a plastic welder, you should probably read through this guide to find out. 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.

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 result isn’t always visually appealing. Dried glue smears are unsightly and oftentimes impossible to remove. Also, 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.

PLASTIC WELDER BUYER’S GUIDE

Amount of Power the Plastic Welder is capable of

The power of plastic welders is measured in wattage. Unlike topside creepers, the higher the wattage a plastic welder has, the higher its max heat setting will be. However, in most plastic welders’ guns, 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. Unlike nut drivers, 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, like that in a hot glue gun, a temperature range suitable to your plastic-type, and a visible temperature display in the form of a dial, or display.

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, which is not a feature found in staple guns.

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.

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, like grass shear.

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.

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 the 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, like in digital torque adapters, 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.
