Comprehensive Buying Guide of The Best Plastic Welder

Power of The Plastic Welder

Whereas power is a vital factor to consider when trying determining how useful a piece of equipment is, it can get a bit redundant when searching for the plastic welder kit. Nevertheless, it still is essential for a plastic welder but requires the ideal features for it to make the job much easier.

The power of plastic welders frequently is rated in watts, thus, the more the watts, the hotter the welder can get. However, it requires an air pressure or temperature regulator to prevent this heat from becoming counter-productive. Usually, ensuring the temperature maintains a narrow range to melt the plastic without burning, and this is one of the significant challenges when it comes to plastic welding. Furthermore, burned plastic as well as the seal are fragile and easily break after the slightest stress is placed on them.

Moreover, this challenge is even worse when dealing with hot air guns since the amount of air flowing will intrinsically change the air temperature.

Therefore, the best plastic welder is one which produces enough power but still does not lead to this negatively affecting its practicality.

Pro Tips

There exist three main methods for welding plastic, that is, speed, pendulum, and tack with these different welding techniques neither merely dependent on the application of the equipment nor by the movements.

Also, every technique needs a different attachment, and this has subsequently led to the invention of numerous attachments to aid in their use. With a slight variation in design, each technique can make use of a different attachment.

So, depending on the plastic material being welded, the attachment type also varies with heat guns being useful with more techniques and a broader number of attachments in comparison to contact welders. Usually, contact welders make use of a different kind of attachment, which changes the contact point instead of the superficial component placed on top.

Intended Use

There is no perfect plastic welder which will be ideal for all its consumers. Typically, a professional welder would require an entirely different plastic welder to that which the hobbyist uses to carry out minor repairs. The plastic welders appropriate for experts feature a powerful heating element which usually is equipped with various gauges that control temperature. Additionally, the wealth of the included attachments lets you successfully achieve any type of plastic weld. However, as a hobbyist, you ordinarily require a plastic welder that offers you more speed to effectively make legitimate plastic welds whereas still being affordable and easy to use.

The Heating Type

Generally, there are three different types of plastic welders. The first type is the contact welding which like a soldering iron, heat is applied through its metal tip to the plastic which subsequently starts due to the high temperatures hence forms a desirable joint.

Other plastic welders make use of a focused flame and are closely similar to traditional metal welding. However, these plastic welders utilize super-heated air to melt the plastic, and the air usually does not catch fire but gets hot enough to burn similar to fire.

Finally, the last type of plastic welders utilizes high-frequency or ultrasonic waves to produce heat which consequently melts the plastic. Nevertheless, this kind of plastic welding is only often used by massive, fine or ultrasonic high-frequency projects. Thus, for the limited professionals and consumers, the two kinds of plastic welders which are often used are the contact and hot air plastic welder, with these two being considerably smaller in comparison to ultrasonic.

Furthermore, they both do not need powerful generators similar to high-frequency welders, are very much smaller and are very affordable. Nevertheless, with contact welders, the scale and scope of your project are often limited since the contact tip needs conductive heat. Also, in terms of size, it is more limited; therefore, contact welders frequently are utilized for smaller projects.

With hot air guns, you have the freedom to work on bigger projects; nonetheless, they still need the use of an air compressor. It subsequently leads to an increase in the cost of more equipment to the project since the air gun frequently requires to be of a better quality unlike lots of other pneumatic tools, thus increasing the initial cost even further.
