Factors to consider when buying plastic welding kits
Power of the plastic welder
Watt is the main criterion to measure the power of any welder. Higher watt refers to the ability of the Welder to raise higher heat. So, before buying any welder, one must focus on the power of the tool. Besides, check if the tool’s airflow can distribute heat evenly to soften the plastic. It will make your task easier. Otherwise, excessive heat with less airflow can entirely ruin the plastic.

Welding type and tip compatibility
Tack, pendulum, and speed are the three types of plastic welding. Each type is distinctive from the others in terms of repairing tasks and tips. So, a buyer firstly should determine for which purpose they are buying the tool. If a person buys a welder based on the repairing task, the output will be more effective and effortless.

The heating type
Different welders have different heating systems. Each heating system is ideal for a specific task. So, try to buy a welder based on the needed heating system. Generally, plastic welders generate heat in 3 ways which are mentioned below:
- Airless: in this case, a metal tip gets connected with the damage point of the plastic and melts it. This type is suitable for small repair tasks.
- heat guns: The Welder throws a blast of hot air to melt the plastic or to join different plastic parts. The heat gun method is ideal for structural repairing tasks.
- UV waves: The Welder uses ultrasonic waves to produce heat in order to melt the plastic. This method is applicable to factory and laboratory work.
Weight
You may require to carry your welding tool for outdoor jobs. You need something light and portable. Consider a package with a plastic casing rather than a metal one, which can be bulky and heavy.
Nozzles and accessories
A welding tool may require some specific accessory nozzles to weld particular plastics. Always make sure your kit is complete with the nozzles and find out if they are easily interchangeable when the need arises and whether you require special rods for a particular type of plastic and nozzle.

How to use a plastic welder safely?
A plastic welder can generate temperatures over thousand degrees. So, the vast heat can cause serious injury in case of any carelessness. Therefore, it is vital to follow some instructions to complete your task accurately while being safe. I have mentioned some of the crucial steps below:
Wear proper clothing and plastic welding equipment
Firstly, a person needs to wear proper attire to escape from any accidents. Try to cover up your whole body. Otherwise, hot plastic splatters can burn your skin. Don’t forget to wear gloves. Most importantly, protective eyewear is a must to save the eyes from excessive heat and hot splatters.
Read the user manual and follow instructions
Anyone who is going to operate the Welder must read the instructions provided by the manufacturers carefully. It can not only save the user from many hassles but also to understand if the tool is going wrong. If you don’t understand any points or face difficulties in operating the Welder, you must contact the manufacturer.

A person needs to try to get familiar with the device thoroughly. It will help the users to understand what to do if anything goes wrong. It is vital to the extent that having sufficient knowledge about Emergency Procedures enhances one’s capability to execute necessary actions as quickly as possible.
Clean work environment
During work time with the Welder, a user needs to ensure that the surrounding is clean enough. Sometimes, a chaotic working environment with thousands of pieces of plastic creates not only mental pressure but also makes the task difficult. Moreover, if you stumble over those piles of plastics, severe damage can occur.
Go through the M.S.D sheets
Many individuals skip the M.S.D Sheets out of negligence. But it is always necessary to examine the MSD sheet before welding. Because, these papers provide critical information, including the presence of a dangerous chemical in the plastic, as well as specifics on fire and explosion threats and suggestions on first aid.
If a user doesn’t have MSD sheets for the type of plastic he is welding with, he may get them from the manufacturer.
Frequently Asked Questions (FAQs)
How does plastic welding work?
A plastic welding tool features a heat gun, also known as a hot air welder. The heat gun produces a jet of hot air, which softens both the parts being joined and the plastic filler rod, which all must be of the same plastic.
Once melted, they join together, and when cooled, the welding becomes strong and can be finished to create a smooth surface.
Does a plastic welding kit work?
Yes, it works so long as you use the right type of rod for that particular plastic you are fixing. Rather than replacing the whole bumper of your car, you can use a plastic welder to fix the crack, and once smoothened, it goes back to its original state.
