7. Käyttöohjeet
- Virta päälle: Press the PWR/SET button to turn on the machine. The LED display will illuminate.
- Valitse hitsaustila: The machine supports different welding modes. For Aluminum to Nickel welding, press the AL/NI button (if available, indicated by a red light) to activate this dedicated mode. For Nickel to Nickel spot welding, ensure the AL/NI button is not pressed.
- Säädä asetuksia: Use the UP and DOWN buttons to adjust welding parameters such as pulse time and preloading delay time. The display shows the current settings and actual pulse current.
- Valmistele työkappale: Ensure the surfaces to be welded are clean and free of oxidation or contaminants.
- Suorita hitsaus: Position the welding tips firmly against the workpiece. The machine will automatically discharge the capacitor to perform the weld. Observe the welding spot quality.
- Verify Weld Quality: A good weld should be fine, uniform, and strong. The machine is capable of welding up to 0.5mm nickel and 0.2mm aluminum.
