Safety
1. Refer to OSHA for recommended PPE.
2. If any melted plastic comes in contact with your skin, wash with borax soap and
water or alcohol.
3. Make sure you are working in a well ventilated area.
4. Keep chemicals such as gasoline, brake uids and other solvents out of the work area.
5. PVC plastics can produce poison gas when burned and should be kept away from
excess heat and ames.
6. Avoid any contact with your skin when using hot air welders and airless welders as
they can produce very high temperatures when in use.
7. Identify a re extinguisher close enough to use if necessary.
8. Always turn o all welding equipment when repair procedures are complete.

System Setup
1. Connect 120V power cable to the back of the unit.
2. Thread 1/4” male coupler plug to air inlet on the back of the unit.
3. Connect air to male coupler plug.
Warning: Incoming Air Pressure
must not exceed 130 psi.
4. Thread the Nitrogen regulator into the nitrogen tank.
5. Connect the gas hose from Nitrogen regulator to the barb tting on the back of the unit.
6. Open the Nitrogen tank valve and set the regulator output pressure to roughly
80 psi.
User Interface Setup
1. Switch on the power. You will be presented with a welcome screen and then the system home
screen.
Air Press - The compressed air pressure set by the Air Control dial. The air keeps the
heating element cool while the hot air gun is not in use.
Gas Press - The nitrogen gas pressure set by the Nitrogen Control dial. The hot air gun
trigger activates the nitrogen gas. You have to adjust the gas pressure while holding
the trigger.
Air Power - The power delivered to the hot air gun. This determines how hot the hot air
gun gets.
Iron Power - The power delivered to the soldering iron. This determines how hot the
soldering iron gets.
2. Use a phillips screwdriver to unlock the Air Control dial by turning counter-clockwise until dial is loose.
For machines with the push-pull type regulators, pull the Air Control dial to unlock it.
3. Turn the dial until Air Press reads 8 psi.
