6.1 Setting Weld Pressure and Clamp Pressure for the Upper
Wheel Module
You must set weld pressure and clamp pressure before you begin welding. The initial settings
you use are only starting points that you will begin with. Both weld pressure and clamp
pressure settings can be adjusted at any time if necessary.
Note
: Weld pressure and clamp pressure must be set only when the machine is at rest (when
both the cylinder and weld cylinder mode select switches are in the AUTO position). The wheels
should be touching and the upper wheel module should be applying clamp pressure only, not
full weld pressure to the wheel.
Here's how to adjust clamp pressure and weld pressure:
1.
With the AIR CYLINDER mode select switches set to AUTO, adjust the clamp pressure
regulator to a pressure that is sufficient to firmly clamp the fabric in position (about 18 psi
/124kpa). Remember this is a starting point and can be adjusted later if necessary.
2.
Now set the weld pressure regulator located left of the clamp pressure regulator. A typical
setting using steel wheels for both the upper and lower wheel would be about 40 psi /
126kpa for most medium and heavy fabrics (16 oz. per yard / 450g fabric and heavier).
Thinly coated or unsupported fabrics may require an adjustment of the pressure setting or
the use of a silicone coated wheel on the upper wheel module.
3.
With your hands removed from between the drive wheels
, place the WELD CYLINDER
selector switch in the ON position. You should be able to see a slight deflection on the lower
wheel module, indicating weld pressure was applied.
4.
Check the WELD PRESSURE gauge. Set it to 40 psi / 276 kpa if necessary. If the knob does
not turn pull it out to unlock it.
5.
Return the WELD CYLINDER selector switch to the AUTO position.
6.2 Starting the Weld Air Pump
Once weld pressure and clamp pressure have been set, you can start the weld air pump that
provides a steady stream of air to the weld head area. You do this using the Air On button on
the Status Screen of the touch screen.
