2. Sigurnosne informacije
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.
- Elektro šok: Ensure the machine is properly grounded. Do not touch live electrical parts. Wear dry welding gloves.
- Pare i plinovi: Work in a well-ventilated area. Use fume extraction if necessary.
- Zrake luka: Protect your eyes and skin from arc rays. Use a welding helmet with appropriate shade and protective clothing.
- Požar i eksplozije: Držite zapaljive materijale dalje od područja zavarivanja. Imajte pri ruci aparat za gašenje požara.
- Opekline: Hot metal and equipment can cause severe burns. Wear protective clothing, gloves, and footwear.
3. Postavljanje
3.1 Raspakiranje i pregled
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 Priključak za napajanje
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 Prizemlje Clamp Veza
Pričvrstite tlo 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. Upute za rad
4.1 Uključivanje/isključivanje
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 Podešavanje struje
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 Odabir elektrode
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 Postupak zavarivanja
- Provjerite nosi li se sva sigurnosna oprema.
- Insert the chosen electrode into the electrode holder.
- Zapalite luk laganim dodirivanjem elektrode s obratkom i brzim podizanjem kako biste uspostavili luk.
- Održavajte konzistentnu duljinu luka i brzinu zavarivanja za optimalnu kvalitetu zavara.
- After welding, allow the workpiece to cool before handling.
5. Održavanje
Redovito održavanje osigurava dugotrajnost i siguran rad vašeg aparata za zavarivanje.
- Čišćenje: 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.
- Pregled kabela: Regularly inspect all welding cables, electrode holder, and ground clamp for damage, cuts, or loose connections. Replace damaged cables immediately.
- Skladištenje: Store the welding machine in a dry, clean environment, away from direct sunlight and extreme temperatures.
6. Rješavanje problema
| Problem | Mogući uzrok | Otopina |
|---|---|---|
| Nema luka ili slab luk | Loša veza s uzemljenjem, neispravna postavka struje, damp elektroda, problem s napajanjem. | Provjerite uzemljenje klamp connection, adjust current, dry electrodes, verify power supply. |
| Stroj se pregrijava | Exceeding duty cycle, blocked ventilation. | Allow machine to cool, clear ventilation openings, reduce welding time. |
| Loša kvaliteta zavara | Incorrect current, wrong electrode, improper technique, dirty workpiece. | Adjust current, select correct electrode, refine welding technique, clean workpiece. |
