- Strømlys: Indicates the machine is powered on.
- Temperature Light: Illuminates if the machine overheats. Welding should cease until the light turns off.
- Digital skærm: Viser den aktuelle svejsning ampslette.
- Strømjusteringsknap: Bruges til at indstille den ønskede svejsestrøm (amperage).
- Positiv terminal (+): Connects to the electrode holder cable.
- Negativ terminal (-): Connects to the earth clamp kabel.
3. Opsætning
Follow these steps to prepare your welding machine for operation:
- Tilslut jord Clamp: Indsæt jorden clamp cable connector into the negative (-) terminal on the front panel of the welding machine. Twist clockwise to secure. Attach the earth clamp sikkert fastgjort til emnet eller svejsebordet, hvilket sikrer god elektrisk kontakt.
- Connect the Electrode Holder: Insert the electrode holder cable connector into the positive (+) terminal on the front panel. Twist clockwise to secure.
- Indsæt elektrode: Securely place the welding electrode into the electrode holder. Ensure the electrode size is appropriate for the welding current and material.
- Strømtilslutning: Connect the power cable to the machine's power input at the rear and then plug it into a suitable 220V power outlet. Ensure the power switch on the back of the machine is in the OFF position before plugging in.
- Shoulder Strap (Optional): Attach the adjustable shoulder strap to the designated points on the machine for easier portability during use.
4. Betjeningsvejledning
Once the machine is set up, you can begin welding. Always ensure you are wearing full PPE.
- Tænd: Flip the power switch on the rear of the machine to the ON position. The Power Light on the front panel should illuminate.
- Juster strøm: Use the Current Adjustment Knob to set the desired welding amperage. The digital display will show the selected current. Refer to electrode manufacturer guidelines for recommended current settings based on electrode diameter and material thickness.
- Start buen: Bring the electrode into contact with the workpiece at an angle, then quickly lift it slightly to establish an arc. The machine's Hot Start function assists in easier arc initiation.
- Maintain Arc: Maintain a consistent arc length and travel speed. The Arc Strength function helps maintain arc stability during welding.
- Forhindre klæbning: If the electrode sticks to the workpiece, the Anti-Glue function will reduce the current to help prevent the electrode from overheating and fusing, allowing for easier detachment.
- Monitor temperatur: If the Temperature Light illuminates, stop welding immediately and allow the machine to cool down. Do not resume operation until the light turns off.
- Færdig svejsning: Once welding is complete, turn off the machine using the power switch and disconnect it from the power outlet. Allow the workpiece to cool before handling.
