2. معلومات السلامة
Welding operations involve significant risks. Always adhere to safety precautions to prevent electric shock, burns, fire, and exposure to fumes. This machine is designed for Manual Metal Arc (MMA) welding.
- صدمة كهربائية: Ensure the machine is properly grounded. Do not touch live electrical parts. Wear dry welding gloves.
- الأبخرة والغازات: Work in a well-ventilated area. Use fume extraction if necessary.
- أشعة القوس: Protect your eyes and skin from arc rays. Use a welding helmet with appropriate shade and protective clothing.
- Fire and Explosions: أبقِ المواد القابلة للاشتعال بعيدًا عن منطقة اللحام. جهّز مطفأة حريق جاهزة.
- الحروق: Hot metal and equipment can cause severe burns. Wear protective clothing, gloves, and footwear.
3. الإعداد
3.1 فك العبوة والتفتيش
Carefully remove the welding machine from its packaging. Inspect the machine for any signs of damage that may have occurred during transit. Ensure all components listed in the packing list are present. If any damage or missing parts are found, contact your supplier immediately.
3.2 توصيل الطاقة
The Telwin Linear 340-819020 operates on a 230-400V power supply. Ensure your power source matches these requirements. Connect the machine to a suitable power outlet using the provided cord. Verify that the power circuit is adequately protected by a fuse or circuit breaker.
3.3 Electrode Holder Connection
Connect the electrode holder cable to the appropriate terminal on the welding machine. For DC welding, the polarity depends on the electrode type and welding application. Consult your electrode manufacturer's recommendations for correct polarity.
3.4 الكلور الأرضيamp اتصال
نعلق الأرض clamp cable to the workpiece. Ensure a clean, solid electrical connection to the base metal to facilitate a stable arc. A poor ground connection can lead to an unstable arc and poor weld quality.

4. تعليمات التشغيل
4.1 تشغيل/إيقاف التشغيل
To power on the machine, switch the main power switch to the 'ON' position. The indicator light will illuminate. To power off, switch the main power switch to the 'OFF' position.
4.2 التعديل الحالي
The Telwin Linear 340-819020 features stepless regulation of the welding current. Use the adjustment knob on the front panel to set the desired welding current. Refer to the electrode manufacturer's recommendations for appropriate current settings based on electrode diameter and material thickness.
4.3 اختيار القطب الكهربائي
This machine is compatible with a wide range of electrodes, including rutile, basic, stainless steel, cast iron, and aluminum electrodes. Select the appropriate electrode type and diameter for your specific welding application and material.
4.4 عملية اللحام
- تأكد من ارتداء كافة معدات السلامة.
- Insert the chosen electrode into the electrode holder.
- قم بإشعال القوس الكهربائي عن طريق لمس القطب الكهربائي بقطعة العمل برفق ورفعه بسرعة قليلاً لتأسيس القوس.
- حافظ على طول قوس ثابت وسرعة حركة ثابتة للحصول على جودة لحام مثالية.
- بعد اللحام، اترك قطعة العمل لتبرد قبل التعامل معها.
5. الصيانة
تضمن الصيانة الدورية طول عمر ماكينة اللحام الخاصة بك وتشغيلها الآمن.
- تنظيف: Periodically clean the machine's exterior with a dry cloth. Ensure ventilation openings are free from dust and debris. Use compressed air to clean internal components if necessary, ensuring the machine is unplugged.
- فحص الكابلات: Regularly inspect all welding cables, electrode holder, and ground clamp for damage, cuts, or loose connections. Replace damaged cables immediately.
- تخزين: Store the welding machine in a dry, clean environment, away from direct sunlight and extreme temperatures.
6. استكشاف الأخطاء وإصلاحها
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| لا يوجد قوس أو قوس ضعيف | Poor ground connection, incorrect current setting, damp electrode, power supply issue. | تحقق من الأرض clamp connection, adjust current, dry electrodes, verify power supply. |
| ارتفاع درجة حرارة الآلة | Exceeding duty cycle, blocked ventilation. | Allow machine to cool, clear ventilation openings, reduce welding time. |
| جودة لحام رديئة | Incorrect current, wrong electrode, improper technique, dirty workpiece. | Adjust current, select correct electrode, refine welding technique, clean workpiece. |
