Informació de seguretat
ADVERTÈNCIA: La soldadura pot ser perillosa. Seguiu sempre les precaucions de seguretat per evitar lesions o la mort.
- Descàrrega elèctrica: Pot matar. No toqueu les parts elèctriques actives. Porteu guants de soldadura secs i roba de protecció. Assegureu-vos que la màquina de soldar estigui correctament connectada a terra.
- Fums i gasos: Pot ser perillós per a la salut. Mantingueu el cap allunyat dels fums. Utilitzeu la ventilació o l'extracció per eliminar els fums i els gasos de la zona de respiració.
- Raigs d'arc: Can burn eyes and skin. Wear a welding helmet with a proper shade filter to protect your eyes and face. Wear appropriate protective clothing to protect your skin.
- Incendi i explosió: Les espurnes de soldadura i el metall calent poden provocar incendis. Mantingueu els materials inflamables allunyats de la zona de soldadura. Tingueu a mà un extintor.
- Soroll: Can damage hearing. Wear ear protection.
- Always ensure the work area is clean, dry, and well-ventilated.
- Disconnect power before servicing or moving the welding machine.

- Solar Battery Panel: Powers the auto-darkening filter and charges the internal battery.
- Headgear Tightness Knob: Adjusts the fit of the helmet headgear for comfort and stability.
- Sensor d'arc: Detects the welding arc and triggers the auto-darkening function.
- Inner Filter: The auto-darkening lens assembly.
- Dark Shade Knob: Adjusts the dark shade level (DIN 9-13) for different welding processes and amperages.
Lens Display and Controls
Image: Close-up of the DEKO MZ350T Auto-Darkening Welding Helmet lens display, showing the replaceable lithium battery (CR2032), delay control, and sensitivity control.
- Replaceable Lithium Battery (CR2032): Provides backup power for the auto-darkening filter.
- Control de retard: Adjusts the time it takes for the lens to return to its light state after welding stops.
- Control de sensibilitat: Adjusts the sensitivity of the arc sensors to detect the welding arc.
Configuració
Welding Machine Setup
- Col·locació: Place the welding machine on a stable, level surface in a well-ventilated area, away from flammable materials. Ensure the rear vent is unobstructed.
- Connecteu Terra Clamp: Connecteu la terra clamp cable to the positive output terminal (+) on the front panel. Securely attach the earth clamp a la peça de treball o a la taula de soldadura, garantint un bon contacte elèctric.
- Connecteu el portaelèctrodes: Connect the electrode holder cable to the negative output terminal (-) on the front panel. Insert the welding electrode into the electrode holder.
- Connexió d'alimentació: Ensure the power switch on the rear panel is in the OFF position. Connect the power input cable to a suitable AC 1~220V power outlet.
Welding Helmet Setup
- Ajustar el casc: Fit the helmet on your head and adjust the headgear tightness knob for a comfortable and secure fit. Ensure the helmet sits evenly and the viewing area is aligned with your eyes.
- Comproveu la bateria: Verify the internal CR2032 battery is installed and functional. The solar panel will help maintain the charge.
- Set Shade Level: Adjust the dark shade knob to the appropriate DIN level (9-13) for your welding application. Refer to welding safety standards for recommended shade levels.
- Set Sensitivity and Delay: Adjust the sensitivity control to ensure the arc sensors reliably detect the welding arc. Adjust the delay control to your preference for the lens to return to its light state.
Instruccions de funcionament
Welding Machine Operation
- Encès: Turn the power switch on the rear panel to the ON position. The power indicator light on the front panel should illuminate.
- Ajustar el corrent de soldadura: Use the welding current adjustment knob to set the desired amperage. The current meter will display the selected value.
- Començar la soldadura: With the helmet on and properly adjusted, strike an arc with the electrode. The helmet lens will automatically darken.
- Monitor Overheating: If the overheating indicator light illuminates, stop welding immediately and allow the machine to cool down. Do not turn off the machine, as the fan needs to operate for cooling.
- Apagar: After completing your work, turn the power switch to the OFF position and disconnect the machine from the power supply.
Welding Helmet Operation
- Comprovació prèvia: Before each use, ensure the helmet is clean and free from damage. Check that the lens is clear and the sensors are unobstructed.
- Funció d'enfosquiment automàtic: When an arc is struck, the arc sensors will detect the light, and the lens will automatically darken within 1/15000 seconds to the preset shade level.
- Return to Light State: After the arc is extinguished, the lens will return to its light state after the set delay time.
