Instructions

This machine is with two working modes: time mode and continuous mode.

1) The timing mode: user set the heating time, it will stop heating when time is up, then it give alarm. The continuous mode: The machine keeps heating unless the user close heating switch by hand.

2) Mode setting and conversion: The green indicator light is the working mode status light. The green indicator light is bright if open the machine, press SET , the green indicator light turns off, press SET three times, the green indicator light is bright again, repeatedly operate according to this.

The mode selection method
The green indicator light turn on, open the “WARM” switch	The machine is in the continuous mode
The green indicator light turn off, open the “WARM” switch	The machine is in the time mode

Press “▲” and “▼” adjust the temperature.

The machine need preheat firstly before use it.

1. Basic operation：

1) Check the power line.

2) Press”ON”，press “SET”, enter the parameters set interface.

3) Set heating time( This time is only effective in timer mode, if the machine is in persist mode, can press “SET” two times, skip the settings)

Press “▲”up，“▼”down, adjust minutes to your number(0-99 minutes)

Press“SET”, set the seconds, turn seconds to your number(0-59 seconds)

4) Set the heating plate working temperature

After time setting, press “SET” again; change to temperature setting, the clock digital tube display “FF:FS”, as following:

Press “▲”up，“▼”down , adjust temperature to your number(0-450℃)

5) Set work mode, start heating

Time mode: Press “SET” several times, until the green indicator light power off, open the preheating switch (WARM), start heating. The red indicator light turn on, digital tube start timing.

Continuous mode: Press “SET” several times, until the green indicator light turn on, open the preheating switch (WARM), start heating. The red indicator light turn on, digital tube start timing.

6) Stop heating

Heating finished, turn off the heating switch(WARM), the red indicator light power off, the heating plate stop heating(if the machine is in time mode, until the time is up, the machine will stop heating automatically and the digital tube stop timing, the warning buzzer rang two times.)

7) Cooling down

Open cooling switch (COOL), cross-flow fan start working, until the temperature of heating plate drop to normal temperature, turn off the cooling switch (COOL).

8) Power off

Turn off the power switch(POWER)，pull off the power line.

2. SMD desoldering method

1) According to the size of the PCB board and welding process requirement, set the machine work mode and heating plate output temperature.

2) Open heating switch(WARM), heating plate start working, display temperature rise, until displayed temperature reach setting number, wait for a moment, make the heating plate panel temperature even.

3) Put the PCB board on the heating plate, until the solder paste melt, take down the SMD with tweezers or vacuum pen.

4) Work finished, take down the PCB board from heating plate, turn off the heating switch (WARM) and the power switch.

3. SMD soldering method

1) According to the size of the PCB board and welding process requirement, set the machine work mode and heating plate output temperature(Suggest setting in time heating condition, according to the experience setting time, which can effectively prevent PCB overly heating ).

3) Put the PCB board on the heating plate.

4) The time is up, the heating plate stop heating, check if solder paste is completely melted, if melting is not complete, adjust the timing time, and continue heating. Until solder paste completely melted, take down the PCB board from heating plate. Until solder paste cool and curdle, soldering work finished.

5)Turn off and turn on the heating switch(WARM) each time, use the last setting parameters acquiescently, go to the next piece of PCB board soldering.

6) All the soldering finished, turn off the heating switch(WARM) and power switch.

Caution

1. High temperature operation, pay attention to safety, avoid burning.

2. Keep heating plate clean, clean with anhydrous alcohol regularly.

3. If there are some tin slag on heating plate, clean it in molten state (Don’t use the blade or metal edge tool doctoring, in order to avoid the scratch heating plate).

4. If there are some flux on heating plate, turn off the power switch. In normal temperature condition, put some cleanser on heating plate, until

residue dissolved; use soft cloth to wipe gently. Use soft cloth with

anhydrous alcohol wipe the heating plate.

5. Long-time no use, should cramp out the power source plug!
