5. Einrichtung
- Stromanschluss: 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).
- Boden-Clamp Verbindung: Befestigen Sie den Boden 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.
- Anschluss des Elektrodenhalters: Attach the electrode holder cable to the positive (+) terminal on the welder. Insert the appropriate electrode into the electrode holder.
- Elektrodenauswahl: 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.
- Aktuelle Einstellung: 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. Bedienungsanleitung
- Vorbereitung: Ensure all safety precautions are observed. Wear full PPE. Prepare the workpiece by cleaning off any rust, paint, or grease.
- Einschalten: Schalten Sie das Schweißgerät mit dem Hauptschalter ein.
- Einen Bogen schlagen: 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 Antihaft to prevent the electrode from sticking.
- Schweißen: Maintain a consistent arc length and travel speed. The Bogenkraft feature helps maintain arc stability during welding.
- Fertigstellung: Once welding is complete, lift the electrode from the workpiece. Turn off the welder. Allow the workpiece to cool before handling.
7. Wartung
- Reinigung: Reinigen Sie die Außenseite des Schweißgeräts regelmäßig mit einem trockenen Tuch. Achten Sie darauf, dass die Lüftungsöffnungen frei von Staub und Schmutz sind. Verwenden Sie keine Lösungsmittel.
- Kabelinspektion: Periodically inspect welding cables, electrode holder, and ground clamp Bei Beschädigungen, Ausfransungen oder lockeren Verbindungen. Beschädigte Bauteile sofort austauschen.
- Lagerung: Lagern Sie das Schweißgerät in einer trockenen, sauberen Umgebung, fern von direkter Sonneneinstrahlung und extremen Temperaturen.
- Innenreinigung: For internal cleaning, consult a qualified service technician.
8. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Kein Strom | 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/low-voltage Schutz. | Allow welder to cool down. Check input voltage. Reduce duty cycle. |
| Arc difficult to strike or unstable | 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 kleben häufig | Current too low, improper technique. | Increase current, improve arc striking technique. The Antihaft feature should help. |
