Nitrogen Welder for Every Budget
Established in 1981, Polyvance was the first company to commercialize nitrogen plastic welding. Since 2006, Polyvance has delivered more nitrogen plastic welders and trained more technicians to plastic weld than all other companies combined. Our expertise allows Polyvance to manufacture the most advanced nitrogen plastic welders and provide the best quality training in the industry.
Polyvance’s Nitro-Fuzer® nitrogen plastic welders are the most advanced and fully featured on the market. Each welder comes with everything you need to make the fastest and strongest plastic repairs on virtually any type of plastic.
Our line of Nitro-Fuzer® welders offers an option to every shop and every budget, from our basic 8002 model to our top-of-the-line 8203. Welding with nitrogen gas creates the strongest welds possible because it eliminates oxidation of the plastic during the welding process. Think of it like TIG welding for plastic; there's no oxidation, no burning, and no weld contamination.
View the table below to see the differences between our nitrogen plastic welders. We have a handy PDF file with information on all 8 welders.
