Urethane Supply Company's 6051 Dual Fuzer hot air welder sets a new benchmark in hot air welder design.
The Dual Fuzer creates the strongest welds on any thermoplastic using Urethane Supply's exclusive new Nitrogen Thermo-Welding process.
Bottled nitrogen gas is used to eliminate oxidation of the weld, greatly increasing its strength.
The gas supply can be switched to compressed air to conserve nitrogen when it's not being used for welding.
To protect the heating element, the Dual Fuzer is equipped with an alarm system to tell the operator if the air flow is too low to safely operate the unit.
Uses nitrogen (N2) to make stronger, more dependable welds!
Benefits:
* Produces the strongest possible weld with nitrogen gas
* Produces repairs much more quickly than airless welding
* When used with our R13 and R14 polypropylene strips, the Dual Fuzer makes strong and quick repairs on PP / TPO bumpers
* Quickly welds any type or thickness of thermoplastic
* Alarm system to warn operator of low air flow to help prevent overheating
* Repairs have outstanding strength when compared to other repair methods, like adhesives or mechanical fasteners

The Dual Fuzer allows you to switch between compressed air and bottled dry nitrogen.
Welding with nitrogen greatly increases the strength of the plastic weld by preventing oxidation of the melted plastic.
Switching to compressed air when not welding (warming up, cooling down, and between welding jobs) will conserve the bottled nitrogen.
The Dual Fuzer uses a pressure switch-activated heating element protection circuit.
When the pressure to the heating element drops below 0.3 psi, the electricity flow to the element will automatically be shut off and an alarm will sound to tell the technician that gas pressure should be increased.
Set-Up Instructions:
The Dual Fuzer needs two gas hookups: compressed air and dry, bottled nitrogen.
The compressed air should be dry and oil-free, with a minimum pressure of 25 psi to the inlet.
Bottled nitrogen can be purchased from your local welding supply store.
The regulator is the most important part of the system.
We recommend a high-quality twostage regulator designed for use on shielding gas bottles (CGA #580 inlet).
McMaster-Carr Supply Company is a good source for all these components, but all would be available from your local welding supply and hardware
stores.
Instructions for initial use:
1. Hook up air and nitrogen lines
Hook up compressed air and nitrogen to the Dual Fuzer per the set-up instructions.
Looking from the front of the Dual Fuzer, the air line should go into the left side inlet and the nitrogen should go in the right side inlet.
Using the supplied quick-disconnect fitting, attach the heating element to the Dual Fuzer unit.
Do not plug the gray heating element plug into the receptacle in the Dual Fuzer box yet.
2. Test that gas flows through element
Before plugging the unit in, test that the gas flows through the heating element.
Turn valve on top of the Dual Fuzer to select either the air side or the nitrogen.
Turn on the air to the unit and adjust the regulator to get the right air flow.
Switch the valve to the nitrogen side and adjust the flow of nitrogen with the regulator.
You should have gas flow through both sides.
3. Test element protection circuitry
Plug the Dual Fuzer into a power source, but leave the gray power cord disconnected from the receptacle on the
box for now (so there’s no risk of burning out the heating element).
Allow air to flow through the element.
Turn on the main power switch.
The light above the power switch should come on.
Turn the temperature control on to the TPO welding zone.
The light above the receptacle should turn on.
Turn the gas selector valve to the off position.
The light above the receptacle should turn off and the alarm should ring.
When the airflow through the element is restored, the alarm should go off and the light should come back on.
(Note: if the alarm still rings after restoring airflow, increase pressure slightly to turn the alarm off.)
Assuming there are no problems in this procedure, plug in the element and the Dual Fuzer is ready to use.
Instructions for use:
1. Get air flowing through element first
Turn the selector valve to the air side and allow air to flow through the element.
Adjust flow to the desired level.
2. Turn on the power and the heat to the element
Turn on the main power switch.
If the alarm sounds, increase air pressure until it turns off.
Turn the temperature control switch to the TPO welding zone.
Hot air should begin flowing from the tip.
Allow about five minutes to warm up properly.
3. Switch to Nitrogen to weld, back to air if you’re not welding
When the welder is warmed up and you’re ready to weld, turn the selector valve to the nitrogen side.
Adjust the pressure if necessary to turn off the alarm and to set the proper flow.
When you’re finished welding, switch back to air to avoid wasting the nitrogen.
4. When finished, let air flow through the element until it cools off completely
When you’re finished welding for the day, turn off the power to the element but let the air flow through the element
for at least ten minutes until the air coming from the element is completely cool.
Increase air flow to speed up this process.
This is the most critical step for extending the life of your heating element.
DO NOT ALLOW THE ELEMENT TO BE HOT WITHOUT AIR FLOW! THIS WILL KILL YOUR ELEMENT!
