2. Informació de seguretat

ADVERTÈNCIA: La soldadura pot ser perillosa. Seguiu sempre les precaucions de seguretat per evitar lesions o la mort.

• Descàrrega elèctrica: Can kill. Ensure proper grounding. Do not touch live electrical parts. Wear dry gloves.
• 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 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.
• Incendi i explosió: Les espurnes de soldadura poden causar incendis o explosions. Mantingueu els materials inflamables allunyats de la zona de soldadura. Tingueu a mà un extintor.
• Parts calentes: Pot causar cremades greus. Deixeu que l'equip es refredi abans de tocar-lo.
• Soroll: El soroll excessiu pot danyar l'oïda. Feu servir protecció auditiva.

5. Configuració

5.1 Welder Unit Setup

1. Connexió d'alimentació: Connect the welder to a suitable 110V or 220V power outlet using the provided adapter cord. The machine automatically detects the input voltage.
2. Terra Clamp Connexió: Enganxa el terra clamp cable to the designated ground terminal on the welder. Securely attach the ground clamp a la peça de treball o a la taula de soldadura per garantir una bona connexió elèctrica.
3. Instal·lació de la bobina de filferro:
   • Obriu el compartiment de la bobina de filferro.
   • Place the appropriate wire spool (flux core or solid wire) onto the spindle.
   • Thread the wire through the drive roller mechanism. Ensure the correct drive roller groove is used for the wire size.
   • Close the compartment and adjust the tension on the drive roller to prevent slipping or crushing the wire.
4. Connexió de la torxa MIG: Connect the MIG torch to the front panel of the welder. Ensure it is securely fastened.
5. Gas Connection (for Gas MIG): If performing Gas MIG welding, connect the gas hose from your shielding gas cylinder (e.g., CO2/MIX) to the "GAS IN" port on the welder. Ensure all connections are tight to prevent gas leaks.
6. Electrode Holder / TIG Torch Connection (for Stick/Lift TIG): For Stick welding, connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal. For Lift TIG, connect the TIG torch to the negative (-) terminal and the ground clamp al terminal positiu (+).

5.2 Configuració del casc de soldadura

1. Headgear Adjustment: Adjust the headgear straps to ensure a comfortable and secure fit on your head. The helmet should sit firmly without being too tight.
2. Ajust de sensibilitat: Locate the sensitivity knob on the helmet's lens cartridge. Adjust it according to the ambient light conditions and the welding process to ensure the lens darkens appropriately when an arc is struck.
3. Ajust de retard: Adjust the delay knob to control how long the lens remains dark after the arc stops. A longer delay is useful for high amperage welding to prevent eye strain from residual glow.
4. Ajust de l'ombra: Set the shade level according to the welding process and amperage. Refer to standard welding shade charts for guidance. The helmet offers shades 5-8/9-13.
5. Botó de prova: Press the "TEST" button to verify the auto-darkening function before welding. The lens should momentarily darken and then return to clear.
