4. Postavljanje

1. Raspakiranje: Pažljivo izvadite sve komponente iz ambalaže. Pregledajte ima li oštećenja tijekom transporta.
2. Plasman: Place the main unit on a stable, heat-resistant, and non-flammable surface. Ensure adequate clearance for ventilation.
3. Alati za spajanje: Connect the soldering iron, hot air gun, and desoldering gun to their respective ports on the front panel of the main unit. Ensure connections are secure.
4. Priključak za napajanje: Connect the power cord to the unit and then to a grounded 230V AC power outlet.
5. Početni pregled: Before powering on, ensure all accessories are correctly placed and no loose connections are present.

5. Upute za rad

5.1 Opći rad

1. Uključivanje/isključivanje: Use the main power switch on the front panel to turn the unit on or off. The LCD display will illuminate upon power-on.
2. Podešavanje temperature: Use the up/down arrow buttons next to each tool's display to adjust the temperature.
3. Memorijski kanali: The unit features 6 preset memory channels (3 for soldering/desoldering, 3 for hot air). Press the 'Memory' button to cycle through or save settings.

5.2 Stanica za lemljenje

The soldering iron offers precise temperature control for various soldering applications.

• Raspon temperature: 200°C do 480°C.
• Operacija: Set the desired temperature using the controls. Allow the iron to heat up. Apply solder to the joint while touching the tip to the component lead and pad.
• Stanje mirovanja: The soldering iron features a sleep mode (0-99 minutes) to minimize wear and allow for quick startup.

5.3 Hot Air Rework Station

Ideal for SMD component rework, heat shrinking, and plastic welding.

• Raspon temperature: 100°C do 480°C.
• Automatski način rada: When the hot air gun is placed in its holder, it will cool down below 100°C and then turn off, reducing wear and saving energy.
• Ručni način rada: The hot air gun continues operating even when placed in its holder, useful for continuous work.

5.4 Stanica za odlemljivanje

The desoldering gun provides efficient removal of solder from through-hole components.

1. Raspon temperature: 380°C do 480°C.
2. Zagrijte: Set the desired temperature and allow approximately 3 minutes for preheating. The buzzer will beep when ready.
3. Odlemljivanje: Cover the solder joint with the nozzle, allow the solder to melt completely, then press the trigger to extract the molten solder.

5.5 Suction Pen

The suction pen utilizes the built-in vacuum motor to assist in lifting larger integrated circuits (ICs) after desoldering with hot air.

• Operacija: Attach an appropriate suction nozzle to the pen. After heating the IC with the hot air gun until the solder melts, place the suction cup onto the IC and activate the vacuum to lift it.
• Mlaznice: Various sizes of suction pen nozzles are included to accommodate different component sizes.

6. Održavanje

Regular cleaning and maintenance ensure optimal performance and longevity of your YIHUA 948-II station.

1. Čista komora za lemljenje: Regularly clean the solder collection chamber of the desoldering gun to prevent blockages.
2. Očistite oprugu filtera: Remove and clean the filter spring to maintain proper suction.
3. Čiste mlaznice: Use the provided cleaning pins to clear any solder residue from the desoldering nozzles.
4. Očistite usisnu posudu: Ensure the vacuum receptacle is free of debris.
5. Održavanje vrha lemilice: Clean the soldering iron tip after each use and re-tin it with a layer of fresh solder to prevent oxidation.

6.1 Briga o mlaznicama

Sve mlaznice za odlemljivanje dolaze prethodno pokositrene radi zaštite od oksidacije. Ovo je zaštitni dizajn i ne ukazuje na začepljenu mlaznicu.

1. Turn ON the station and allow it to preheat for approximately 5 minutes.
2. Once preheating is complete, press the desoldering trigger to extract the pre-tinned solder on the nozzle.
3. It is recommended to use the desoldering station at 380-400°C for most applications.
4. Avoid keeping the nozzle on the solder pad for too long when using a high-temperature setting to prevent damaging the pad.

7. Rješavanje problema

Ovaj odjeljak nudi rješenja za uobičajene probleme s kojima se možete susresti.

• Bez napajanja: Provjerite priključak kabela za napajanje i glavni prekidač. Provjerite je li utičnica ispravna.
• Alat se ne zagrijava: Verify the tool is securely connected to the main unit. Check the temperature setting and ensure it's not in sleep mode.
• Poor Desoldering Suction: Clean the desoldering gun's solder chamber, filter spring, and nozzle. Ensure the suction pen is properly attached and free of blockages.
• Nedosljedna temperatura: Allow sufficient preheating time. Ensure the heating element is not damaged. If issues persist, contact customer support.
