Top Welder Accessories – The Best for Plastic Welding

When it comes to plastic welding, having the right tools makes all the difference. Using high-quality welder accessories that are designed for specific applications is the best way to ensure a smooth, efficient weld every time. Check out the guide below to see which welding supplies you should add to your list.

Indispensable Accessories

Hand Rollers


Hand rollers are handheld tools that apply pressure to the thermoplastic during a weld to ensure a tight seal. From roofing rollers to seam rollers, these devices feature a user-friendly, ergonomic design and easy grip. They come in various widths and are commonly used for roofing and flooring projects. Hand rollers require minimal pressure. Since users must hold a welder in one hand and a roller in the other, this feature allows them to complete welds easier and quicker than ever.

Generators deliver reliable power during a weld, eliminating the need for utility power.


Plastic Welding Rods

Plastic welding rods are long, cylindrical rods used for applications such as tank welding, plastic repairs, pipe and tube welding, and more. Plastic welding—including TPO welding—uses a combination of air and heat to bond thermoplastics. Welding rods help bond the plastic materials used in this process—including polypropylene, polyethylene, PVC, CPVC, polycarbonate, and ABS.


Industrial Line Cords

Line cords are durable cords that power the metal rod during a weld. They’re often brought onto a roof to provide a continuous power supply for welding tools. One end plugs into the welding tool, while the other end plugs into a power source. Their flexibility makes them easy to move around during a weld.


Accessories That Make Welding More Precise

Heat Gun Nozzles

Heat gun nozzles are interchangeable attachments that fasten to the tip of heat guns to direct the hot air stream onto the welding material. Our nozzles are made of stainless steel, are available in various shapes and sizes, and are designed for specific applications to ensure the most precise welds. Since various nozzles can be compatible with the same welding tool, users don’t need a separate welder for each nozzle.

Adapters convert power to provide the right amount of power for each weld. They make the power source safer and more reliable, enhancing overall precision.


Accessories That Make Welding More Convenient

Standing Profile Wheel

Standing Seam Profile Wheel Kit

A profile kit allows the contractor to install a rib made of the same roofing material as TPO or PVC, which allows the roof to resemble a standing seam roof when completed. This kit makes installations more convenient in the commercial roofing industry.


Accessories That Make Welding More Efficient

Air Hose

Honda Pump WX10 Hose

An air hose is a type of industrial tubing that transfers air from the compressor to the nozzle. These devices are strong yet flexible, which enhances overall efficiency.


Air Filtersairfilter for BAK RiOn welding machine

Air filters protect the welding tool’s internal components from dust and other debris that would impede its operation. This essential feature reduces malfunctions and breakdowns, which enhances operational longevity.
