Polyvance Nitro-Fuzer Digital Single Ga, With Cart and Generator 8203

Product Overview:



The 8203 Nitro-Fuzer combines Polyvance's most advanced plastic welding equipment with the state-of-the-art Nitrocell nitrogen generator. The system includes everything needed to become immediately productive making strong and fast plastic repairs on virtually any type of plastic. Using nitrogen gas to weld plastic creates superior strength bonds by eliminating oxidation while the plastic is heated.

The 8203 Nitro-Fuzer simplifies nitrogen plastic welding by using a continuous flow of nitrogen gas. Eliminating the compressed air source allows the welder to run on nitrogen 100% of the time and eliminates the need to switch back and forth from air to nitrogen. Using only nitrogen also helps the heating element last longer by reducing oxidization. Plus, the Nitrocell generator system allows the strongest welds to be made without the worry of ever running out of nitrogen.

The 8203 is a technologically advanced plastic welder capable of welding virtually any type of plastic. The analog flow gauge, precision regulator, and digitally encoded temperature controls allow for precise and consistent welds. A pressure sensor shuts off the power to the heating element if the nitrogen pressure drops below a safe level, reducing the likelihood of accidentally overheating the element. The integrated airless welder is used for smoothing welds and repairing thermoset polyurethane. With the 8203 Nitro-Fuzer®, it's never been easier to make high-quality plastic welds.

The system is shipped completely assembled and requires only a few minutes to set up before use. The Setup and Use video and Quick-Start Guide can be found below. The 8203 is packaged with three welding rod organizer cases filled with a large selection of welding rods, a hand seamer, and aluminum tape. It is covered by a two-year "bumper-to-bumper" warranty covering all parts except the heating elements and misuse.

Application Tips


  • Make stronger repairs than with any other method.
  • Profit from repairing plastic rather than replacing it.
  • Make more profit by welding rather than using two-part adhesives.
  • Repair tabs, mounting holes, and slots that are impossible to repair with two-part adhesives.
  • Strength: Make repairs that are stronger than any two-part epoxy or hot air weld. Plastics are melted together with no oxidation to form the strongest possible plastic weld.
  • Speed: Complete repairs in a fraction of the time of two-part epoxies. Typical welding speeds are 4 inches (10 cm) to 6 inches (15 cm) per minute. No waiting for cure time. Cool with water, then sand, prime, and paint.
  • Versatility: Do repairs that are not possible with two-part epoxies: Mounting tabs (thick or thin), grille bars, high-stress areas, flexible tabs, and fender liners. Plus, it's not just for automobile plastics. It can be used on ATVs, boats, motorcycles, appliances, toys, etc.
  • Cost Savings: An average 6 inch (15 cm) repair costs less than $2.00. You pay that much just for the mixing tips when using two-part adhesives. The same adhesive repair can cost over $30.00!
  • Ease: Repairs are simple to do. Your techs already have the skill set; with the 8202 Nitrogen Welding System, they have the tools.
  • Estimating Options: Gives you more flexibility in the estimating process. Save totalled vehicles. Get an edge on the competition. A bargaining tool with insurance adjusters.
  • Keep Profits in Your Shop: No need to replace bumpers, headlights, and other plastic parts. Keep labor dollars in house!
  • Insurance Relations: Show you are on the side of cost savings while increasing your profits at the same time. By making a QUALITY repair you become an ally of insurance adjusters, decrease cycle times, and help steer additional work to your shop.
  • Create Loyal Customers: 25% of a shop’s business is customer-pay. Save customers money on small hits and they will return to your shop with the big hits.
  • Blend in the Panel: Repair the damage to the bumper and blend the color in the panel. Avoid the risks and costs involved in blending into the undamaged fenders.
  • Revolutionize the Repair Process: Just as polyester filler replaced lead, and the wire-fed welder replaced brazing, the nitrogen system will replace all other types of plastic repair.
  • Avoid Fit Issues: Why put on an aftermarket cover when you can easily repair the OEM part?
  • Plastic Use Will Continue to Grow: The amount of plastic parts on cars will continue to grow. This means ever increasing repair opportunities in the future.
  • Factory Support: Plastic is what we do at Polyvance. Since 1981, we have been the leader in product development and problem solving in the plastic repair industry. We have the proven products you need from start to finish. Plastic repair doesn't have to be difficult!
