5. تعليمات التشغيل
- تشغيل الطاقة: Turn on the spot welder. The digital control panel will illuminate.
- Select Material Thickness: Use the control panel to select the thickness of the material you intend to weld. The system will automatically calculate the optimal weld duration. Refer to Image 5.1 for control panel details.
- Pulse Mode (Optional): For high-stress steels, activate the pulse mode via the control panel if required.
- ضبط المعلمات (اختياري): If necessary, you can manually override the automatically selected weld parameters using the controls.
- موضع قطعة العمل: Place the materials to be welded between the electrodes. Ensure good contact and alignment.
- بدء عملية اللحام: Firmly press the operating lever. The weld will only start when sufficient pressure is applied, preventing accidental firing. Hold the lever until the weld cycle is complete.
- فحص اللحام: After the weld, release the lever and carefully remove the workpiece. Inspect the weld for quality and penetration.
- يكرر: Continue welding as needed, ensuring electrodes remain clean and properly aligned.

6. الصيانة
Regular maintenance ensures the longevity and optimal performance of your spot welder. Always disconnect the power before performing any maintenance.
- فحص القطب: Regularly inspect electrodes for wear, pitting, or mushrooming. Worn electrodes should be dressed or replaced to ensure consistent weld quality.
- تنظيف: Keep the welder clean and free from dust and metal particles. Use a dry cloth to wipe down the casing. Avoid using solvents that could damage the composite materials.
- Arm and Jaw Inspection: Check the welding arms and jaws for any signs of damage or looseness. Ensure all fasteners are tight.
- فحص الكابلات: Periodically inspect the power cable and welding cables for cuts, abrasions, or signs of heat damage. Replace damaged cables immediately.
- تخزين: قم بتخزين جهاز اللحام في بيئة جافة ونظيفة عندما لا يكون قيد الاستخدام.
7. استكشاف الأخطاء وإصلاحها
If you encounter issues with your Sealey SR123 Spot Welder, refer to the following common problems and solutions:
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| No power to the welder | Power cable unplugged, circuit breaker tripped, faulty power switch. | Check power connection, reset circuit breaker, contact qualified service personnel if switch is faulty. |
| Poor weld quality or no weld | Dirty electrodes, worn electrodes, incorrect material thickness setting, insufficient pressure, dirty workpiece. | Clean or replace electrodes, verify material thickness setting, ensure firm pressure on operating lever, clean workpiece surfaces. |
