Best Plastic Welder Buying Guide 2021

Consider Before Buying the Best Plastic Welder

Before shopping for the plastic welding kit, you have to do your homework thoroughly. Failure to do so means, buying a product that will not deliver the results you need. To help you with your shopping experience, we have researched factors to consider before buying a plastic welder.

Here are the important things to take into account before buying a plastic welder.

  • Which Is the Best Heating Type?

In the market, you will come across three types of plastic welders. You have airless or contact welders, heat guns and high-frequency models. The airless model comes with a metal tip. When heated, it melts the plastic material.

This tool is useful for projects that need small or filler welds. The airless plastic welder model cannot make repairs to the structural integrity of the plastic material. This is because they form a thin bond between plastic materials just like glue.

Heat guns blast hot air softening the plastic material. Designed with microprocessors, they control the temperature allowing you to weld plastic materials together. Since plastic welder gun softens plastic materials, they create a stronger bond. This makes them suitable for structural repairs.

The last type generates ultrasonic waves to melt the plastic. This is commonly used in labs and factories.

  • How Much Power Do You Need?

Power is a top consideration when shopping for a plastic welder. Some models will have a higher wattage while others will not. For melting tough plastic, we recommend choosing a plastic welder with 200 W and over.

This will soften the plastic and create a strong bond. For repairing surface cracks, we recommend a plastic welder with 200 W and below.

Airflow goes hand in hand with heat generated. If the plastic welder generates too much heat but poor airflow, the repairs take longer. Also, the heating element will burn out and damage the welder. If there is too much airflow and little heat, the airflow will impact the weld.

DIY plastic welding should generate consistent airflow and heat.

  • What Type of plastic Are You Welding?

In plastic welding, there are three primary techniques: speed, tack, and pendulum. Each technique is suitable for different projects. Also, each technique produces a different type of weld.

What you need to know is that different tips produce a variety of welding styles. Some are effective while others are not. Welders can use different types of tips to assist in their repairs.

For example, you have the flat slit nozzle, pencil tip nozzle, triangle speed welding nozzle, and round speed welding nozzle. To have different designs when making repairs, use suitable attachments.

  • Are You a Hobbyist or a Professional?

Not all plastic welders are suitable for all repair jobs. Some can make stronger bonds while others cannot. If you are a hobbyist, we recommend that you choose an easy to use device. It should have a wattage of less than 200 W. Also, it’s should be inexpensive.

For professionals, we recommend powerful and high wattage plastic welders. These welders have a temperature gauge and microprocessors. As such, users can adjust the temperature depending on the project
