Heating Power: 800W
Plate Area: 180mmx200mm
Plate Material: AL
Temperature Sensor: K Type Thermocouple
Temperature: 50℃～300℃
Ambient Temperature: 0～40℃
Temperature Stability: ±2℃
Outer Dimension: 280(W) x290 (L) x100 (H) mm

2. Features:
• Even temperature distribution.
• CPU closed loop temperature control, digital display, zero Voltage heater switching.
• Dedicated power and heating switches.
• ESD safe.
• External temperature calibration.
• Hinged hood creates an oven like environment for reflow.
• Two heating states optional (Pre-heating ＆reflow).

3. Operation:
• Plug the power cable.
• Turn on the power switch.
• Pre-heat plate temperature will be displayed after the set temperature is displayed for 2
seconds.
• Adjust the up or down arrow keys to change the set temperature (see temperature
adjustment).
• Turn on the heating switch, the unit starts heating. It will reach the set temperature in a few
minutes.
• The unit may be used as a pre-heat plate when the cover is moved back or as a mini reflow
oven when the cover is over the plate.
• Turn off the heating switch after a circuit board is done.
• Turn off the power switch at the end of the work.
Note: Be aware of the high temperature on the plate and its surrounding areas.
4. Temperature Setting and Adjustment
Temperature can be set in two ways:
(a). Regular setting:
Turn the heating switch off.
Press the ‘*’ key for at least 1 second.
1) The 100th digit flashes. It indicates that the unit has entered into temperature setting
mode. The 100th digit may be changed.
2) Use the ‘▲’ or‘▼’keys to go through the valid numbers as shown below:
1 2 3 4
While the desired number is displayed, press the ‘*’ key to enter it and switch to the 10th
digit position. The 10th digit flashes.
3) Use the ‘▲’ or ‘▼’ keys to cycle through the valid numbers as shown below:
1 2 3 4 5 6 7 8 9 0
Press the ‘*’key to enter the desired number and switch to the 1th digit
position.
4) Change to the desired number as show in (3).
At the ‘*’ key is pressed at the 1th digit,
a) The selected temperature is saved;
b) It is displayed.
c) It is applied to the heating element.

Notes: if power is off during temperature setting, the new temperature will not be
saved.
• If the “*” key is pressed less than 1 second, the set temperature will be displayed for 2
seconds. Display will be automatically switched back to pre-heat plate temperature.
• After the ‘*’ is pressed, power supply to heating elements will be out off.
• If an invalid temperature is entered, the 100th digit will flash, indicating a valid temperature is
needed.
(b). Temperature Setting during Heating
If it is necessary to change plate temperature quickly while power supply to heat element is still
maintained, the following procedure can be followed:
Raising the temperature:
Press the ‘▲’ key directly without pressing the “*” key. Doing so will raise the set
temperature 1℃. If the ‘▲’ key is released, it will not respond to new input within 2
seconds. Press the ‘▲’ key again after two seconds will raise the temperature another 1℃.
If the ‘▲’key is pressed for least 1 second, the set temperature will be
incremented automatically until the‘▲’key is released.
Lowering the temperature:
Similar to above, the ‘▼’ key is used instead.
