4.1.2 Wheel Pressure Regulators

Figure 15 Wheel Pressure Regulators

These two regulators allow you to adjust wheel pressure. There are two adjustments you can
make here: CLAMP PRESSURE and WELD PRESSURE.

CLAMP PRESSURE is usually set to about 18 psi / 124kpa. WELD PRESSURE is usually set to
about 40 psi / 276kpa, depending on the thickness of the coated fabric and the wheel surface
(steel, silicone or other material). Remember these are only base settings that can be adjusted
later. See Setting WELD PRESSURE

and CLAMP

PRESSURE.
