5. 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 Nitrogen Control dial to unlock it.
6. Hold the trigger and turn the dial until Gas Press reads 2 psi then release the trigger.
7. Use a phillips screwdriver to lock the Air Control dial by turning clockwise until dial is tight.
For machines with the push-pull type regulators, push the Nitrogen Control dial to lock it.
8. Plug the soldering iron into the Iron outlet on the front of the machine.
Warning: Only plug the iron into this outlet. Any other devices may
be damaged.
9. Plug the hot air gun into the plastic welder section on the front of the machine.
Basic Welding Instructions
Identifying The Material
The rst step in plastic repair is identifying the base material of the repair piece. If you look
on the backside of 99.99% of all plastic found in cars, you will nd an ISO code. The ISO
code is an abbreviation for the type of plastic. For example, a common ISO code found on
bumper covers is TPO which is the abbreviation for thermoplastic ole n. If this is the case,
retrieve a TPO rod from your accessory drawer. Refer to Appendix A for ISO Code reference.
Preparing The Surface
Surface preparation is very important to create a strong, lasting weld. Use the 80 grit.
sandpaper provided to prepare the backside of the repair area surface. Use a rotary tool
and conical bit to grind a narrow channel along the surface crack. Use any non-corrosive,
degreaser to clean the surface area of any particulate and oils.
Aligning The Damage
We recommend two alignment methods.
1. Hot Staples (preferred method) - Permanent alignment which provides a long-term
structural reinforcement. Plug the hot staple welder into the cigarette adaptor on
the front of the machine. Follow the illustrated instructions in the hot staple welder
kit to align the damage.
2. Aluminum Tape - Temporary alignment which provides no long-term structural
backing. Simply lay a strip of aluminum tape along the front side of the damaged
area to maintain alignment. Smooth the tape so that it has as much surface contact
as possible. This not only guarantees adhesion but it also prevents heat distortion in
the bumper.
