The Telwin T-ARC 120 features a compact design with intuitive controls for MMA welding. Key components include the current adjustment knob, electrode and ground cable connections, and indicator lights.

Figur 4.1: Front panel of the Telwin T-ARC 120. This image displays the main control knob for current adjustment, the positive and negative terminals for welding cables, and the Telwin branding. The dial indicates current settings from 20A to 80A, with corresponding electrode diameters (1.6mm to 2.5mm).

Figur 4.2: Top view of the Telwin T-ARC 120, showing the carrying strap and a label with technical specifications. The label details electrode compatibility (2.5mm at 80A, 2.0mm at 55A, 1.6mm at 40A) and duty cycle, along with generator compatibility (3kW).
5. Opsætning
- Strømtilslutning: Connect the welder to a suitable power supply (230V +/- 15%). Ensure the power outlet is properly grounded and can handle the required amperage. The unit is compatible with motor generators (3kW).
- Jord Clamp Forbindelse: Fastgør jorden clamp cable to the negative (-) terminal on the welder. Securely attach the ground clamp to the workpiece or a clean, bare metal surface connected to the workpiece.
- Elektrodeholdertilslutning: Attach the electrode holder cable to the positive (+) terminal on the welder. Insert the appropriate electrode into the electrode holder.
- Valg af elektrode: Choose an electrode suitable for your welding material and thickness. The welder supports rutile, basic, stainless, and cast iron electrodes up to 2.5 mm.
- Nuværende indstilling: Adjust the welding current using the knob on the front panel according to the electrode diameter and material. Refer to the specifications or electrode manufacturer's recommendations.
6. Betjeningsvejledning
- Forberedelse: Ensure all safety precautions are observed. Wear full PPE. Prepare the workpiece by cleaning off any rust, paint, or grease.
- Tænd: Tænd svejsemaskinen ved hjælp af hovedafbryderen.
- Striking an Arc: Gently tap or scratch the electrode against the workpiece to strike an arc. Avoid sticking the electrode. The welder features Hot Start for easier arc ignition and Anti-stick to prevent the electrode from sticking.
- Svejsning: Maintain a consistent arc length and travel speed. The Arc Force feature helps maintain arc stability during welding.
- Efterbehandling: Once welding is complete, lift the electrode from the workpiece. Turn off the welder. Allow the workpiece to cool before handling.
7. Vedligeholdelse
- Rensning: Regularly clean the welder's exterior with a dry cloth. Ensure ventilation openings are free from dust and debris. Do not use solvents.
- Kabelinspektion: Periodically inspect welding cables, electrode holder, and ground clamp for skader, flosninger eller løse forbindelser. Udskift beskadigede komponenter med det samme.
- Opbevaring: Opbevar svejsemaskinen et tørt og rent miljø, væk fra direkte sollys og ekstreme temperaturer.
- Indvendig rengøring: For internal cleaning, consult a qualified service technician.
8. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Power cable disconnected, circuit breaker tripped, welder switch off. | Check power connections, reset circuit breaker, turn on welder switch. |
| Welder stops during operation | Overheating (thermostatic protection activated), over-voltage/lav-voltage beskyttelse. | Allow welder to cool down. Check input voltage. Reduce duty cycle. |
| Lysbuen er svær at tænde eller er ustabil | Improper current setting, poor ground connection, damp electrode, incorrect electrode type. | Adjust current, ensure clean and secure ground, use dry electrodes, select correct electrode. |
| Elektroden klæber ofte | Current too low, improper technique. | Increase current, improve arc striking technique. The Anti-stick feature should help. |
