5. Configuració

5.1 Connexió d'alimentació

• Assegureu-vos que el soldador estigui apagat abans de connectar-lo a l'alimentació.
• The AZZUNO MIG-145L supports both 110V and 220V input. Use the provided adapter if converting from 220V to 110V.
• Connecteu el cable d'alimentació a una presa de corrent amb connexió a terra adequada.

5.2 Instal·lació de cables (MIG/nucli de flux)

1. Obriu la tapa del compartiment d'alimentació del filferro.
2. Col·loqueu el carret de filferro al portacarrets, assegurant-vos que giri lliurement.
3. Passeu el cable pel tub guia i dins del mecanisme del rodet impulsor.
4. Adjust the drive roller tension to prevent slipping or crushing the wire. The V-groove drive roller is included for optimal feeding.
5. Tanqueu la tapa del compartiment d'alimentació del filferro.
6. Press and hold the WIRE FEED BUTTON to feed the wire through the MIG torch liner until it exits the contact tip.

5.3 Connexió de gas (MIG de gas)

• For Gas MIG welding, connect your shielding gas cylinder (e.g., CO2/Argon mix) to the gas inlet on the rear of the welder using the provided gas hose and hose bands.
• Assegureu-vos que totes les connexions estiguin ben ajustades per evitar fuites de gas.

5.4 Connexió d'accessoris

• Connect the MIG torch to the appropriate connector on the front panel for MIG/Flux Core welding.
• Connect the electrode holder for Stick welding or the TIG torch (not included) for Lift TIG welding to their respective terminals.
• Enganxa el terra clamp to the workpiece, ensuring a clean, bare metal connection for proper electrical circuit.

8. Solució De Problemes

This section provides solutions to common issues you might encounter. For problems not listed here, please contact AZZUNO customer support.

• Sense energia:
  • Comproveu si el cable d'alimentació està ben connectat a una presa de corrent.
  • Verify the main power switch on the welder is in the 'ON' position.
  • Check the circuit breaker or fuse in your electrical panel.
• Sense arc:
  • Assegureu-vos que el sòl clamp is securely attached to bare metal on the workpiece.
  • Check all cable connections (torch, electrode holder, ground clamp) for tightness.
  • Verifiqueu que s'ha seleccionat el mode de soldadura correcte.
• Poor Wire Feeding (MIG/Flux Core):
  • Check drive roller tension; it should be firm enough to feed wire without slipping but not too tight to deform the wire.
  • Inspect the contact tip for blockage or wear; replace if necessary.
  • Ensure the wire spool is installed correctly and rotates freely.
  • Check the MIG torch liner for kinks or debris.
• Inconsistent Weld:
  • Adjust welding parameters (amperage, voltage, wire speed) to match the material and thickness.
  • Ensure proper shielding gas flow (for Gas MIG).
  • Maintain a consistent travel speed and arc length.
