IMPORTANT NOTE: With all press styles, these instructions will adjust the ram force of the press. The actual applied pressure to your material is:
ram force (lbs) / surface area of material (in2). To maximize pressure, always try to minimize the surface area of your material. A 2″ x 2″ (4in2) square of material will receive 4x less pressure than a 1″ x 1″ square from the same ram force!
There are two adjustments for pressure – the black knob located towards the back of the unit, and adjusting the height of the top plate.
- Adjustment using pressure knob: Turn clockwise to increase pressure or counter-clockwise to decrease pressure.
- Top plate height adjustment: First, make sure the press is powered off and fully cool, then unplug the heater cable going from the top plate to the controller. Next, loosen the top nut that secures the heat plate to the frame. Once the nut is loose you can freely rotate the top heat plate to raise or lower. Raising the plate reduces pressure and lowering increases pressure. Once you reach your desired height, align the top plate with the bottom and re-tighten the top nut, then re-connect the heater cable.
The ram force of the pneumatic press is determined by the system air pressure. This can be adjusted using the knob on the air pressure regulator. The Instruction Manual includes a chart showing the relationship between air pressure and ram force. To calculate the actual psi applied to your material, divide the ram force (from the chart) by the surface area (in2) of your material.
Each heat plate has its own temperature controller. The controller on the left controls the bottom plate and the controller on the right controls the top plate. To adjust temperature press the "OK" button once - P- 1 will display. Press ▲ or ▼ until your desired temp is displayed. Then press "OK" again to confirm and change the display to P-2, and press "OK" once more to return to the temperature readout. Repeat this process with the other control station.
Each heat plate has its own temperature controller. The controller on the left controls the bottom plate and the controller on the right controls the top plate. Simply use the ▲ or ▼ (up and down arrows) to adjust temperature.
The timer function on the manual press is a visual indicator only. On either controller, press "OK" twice so the display reads P-2. Use ▲ or ▼ to adjust the value (in seconds) of the timer, then confirm with "OK". The timer will start automatically when the arm is pulled down, or you can press "ENTER" to start the timer manually. It will visibly count down to zero. Each control station has a separate timer, however both timers will begin countdown once press has been closed. We have found some people like to use both timers for ease of viewing.
Unlike the manual press, the pneumatic model features a more advanced dwell timer that controls the opening and closing of the press. The countdown begins once the footswitch is activated and the press is closed, and once it reaches zero the press is automatically opened again. The only way to open a pneumatic press before the countdown is completed is by pressing the large red Emergency Shut-Off button, which will always open it immediately.
The dwell timer control is located on the far right of the base of the press, next to the large red Emergency Shut-Off button. It is protected by a clear plastic cover that must be temporarily removed to make adjustments. The top display is used for the countdown during the pressing process, and the lower display is used to set the timer length in seconds. Each digit is controlled by its own + and - buttons. For example, if you want to set for a 30 second press, adjust the bottom display to show "030". Once you have entered your desired time, re-attach the clear plastic cover to prevent accidentally changing your set value.
Hold "OK" until you see P-3. Use ▲ or ▼ to toggle between F and C. Hold "OK" until you return to the temperature readout.
The current model of Pneumatic Press only supports temperature display in °F.
The plates are made of aluminum, with a Teflon coating.
We suggest temperatures between 150–300°F (65–150°C) with a press time of 5–30 seconds. In general, the best results will come from lower temperatures and longer times.
While first heating up, maximum draw for the small (5.5″ x 5.5″) press with both heaters powered on is 1320W (11A on a 120V circuit.) While maintaining stable temperature, power draw cycles between 3.5W–500W.
Parchment has been reported to give the best results thus far, and we hope to bring you better material in the future, so stay posted!
