2. Instruccions de seguretat

Always prioritize safety when operating welding equipment. Failure to follow safety guidelines can result in serious injury or property damage.

• Protecció ocular i facial: Always wear a welding helmet with appropriate shade lenses to protect against arc flash and sparks.
• Protecció corporal: Wear flame-resistant clothing, welding gloves, and safety shoes to protect against burns and electric shock.
• Ventilació: Ensure adequate ventilation to remove welding fumes, which can be hazardous to your health. Work in a well-ventilated area or use fume extractors.
• Seguretat elèctrica: Ensure the welder is properly grounded. Do not operate in wet conditions. Inspect cables and connections for damage before each use.
• Prevenció d'incendis: Keep flammable materials away from the welding area. Have a fire extinguisher readily available. Sparks and hot metal can cause fires.
• Àrea de treball: Mantingueu la zona de treball neta i lliure de trastos. Assegureu-vos d'una base estable.
• Llegeix el manual: Read and understand this entire manual before operating the welder.

5. Configuració

5.1 Connexió d'alimentació

• Assegureu-vos que el soldador estigui apagat abans de connectar-lo a l'alimentació.
• The welder supports both 110V and 220V input. Use the appropriate adapter cable provided for your power outlet.
• Connecteu el cable d'alimentació de manera segura a una presa de corrent amb connexió a terra.

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

Imatge 5.1: Interna view of the wire feeding system with a wire spool.

1. Obriu el panell lateral de la soldadora per accedir al compartiment de la bobina de filferro.
2. Col·loqueu el carret de filferro al cargol, assegurant-vos que giri lliurement.
3. Passeu el cable pel tub guia i dins del mecanisme del rodet impulsor.
4. Close the drive roller tension arm and adjust the tension knob. The tension should be firm enough to feed the wire without slipping, but not so tight as to deform the wire.
5. Press and hold the WIRE FEED BUTTON on the control panel to feed the wire through the MIG torch liner until it exits the contact tip.
6. Cut off any excess wire, leaving about 1/2 inch protruding from the tip.

5.3 Connexió de gas (per a gas MIG)

• For Gas MIG welding, connect the gas hose (provided) to the gas inlet on the back of the welder and to your shielding gas cylinder regulator.
• Assegureu-vos que totes les connexions estiguin ben ajustades per evitar fuites de gas.
• Obriu la vàlvula de la bombona de gas lentament.

6. Modes de funcionament

The AZZUNO MIG-145L offers four distinct welding modes:

6.1 Gasless Flux Core MIG Welding

• Ideal for outdoor use or when shielding gas is not available.
• Uses flux-cored wire which produces its own shielding gas as it burns.
• Ensure correct polarity (DCEN - Direct Current Electrode Negative) for flux core.

6.2 Soldadura MIG amb gas

• Requires an external shielding gas (e.g., Argon/CO2 mix for steel, Argon for aluminum).
• Provides cleaner welds with less spatter compared to flux core.
• Ensure correct polarity (DCEP - Direct Current Electrode Positive) for solid wire MIG.

6.3 Soldadura TIG amb elevació

• Provides precise control and high-quality welds, especially on thinner materials.
• Requires a TIG torch (not included in standard package), tungsten electrode, and shielding gas (Argon).
• To initiate arc, touch the tungsten to the workpiece and then lift slightly.

6.4 Soldadura amb electrod enrotllat (MMA)

• Uses coated electrodes (stick electrodes) for welding.
• Suitable for thicker materials and outdoor conditions.
• Connecteu el portaelèctrode al terminal positiu (+) i al connector de terra.amp to the negative (-) terminal for most common electrodes (DCEP).

7. Pantalla i controls

The AZZUNO MIG-145L features an intuitive control panel with a large LED display for easy adjustments.

Imatge 7.1: Detallada view of the welder's large LED display and control interface.

• Selecció del mode: Use the dedicated buttons to select between Flux MIG, Gas MIG, Stick, and Lift TIG modes.
• Pantalla LED gran: Shows current welding parameters (Amperage, Voltage, Wire Feed Speed).
• Botó de control: Adjusts welding current (Amperage) or voltage. Press and hold for 3 seconds to switch between Amp i Voltage ajust.
• Synergic Control (SYN): Press button "A" for 3 seconds to activate. This mode automatically adjusts wire feed speed and voltage based on the selected amperage, simplifying setup for optimal performance.
• 2T/4T/SPOT Settings:

  • 2T (Dos tocs): Press and hold the trigger to weld, release to stop. Ideal for short welds.
  • 4T (Quatre tocs): Press and release trigger to start welding, press and release again to stop. Useful for long welds, reducing hand fatigue.
  • TACA: Allows for timed spot welds. Adjust the spot time as needed.
• VRD/Arc Force/Hot Start: Selectable functions for Stick welding to improve arc stability and starting.

8. Manteniment

Un manteniment regular garanteix la longevitat i el rendiment òptim del vostre soldador.

• Neteja: Regularly clean the internal components with compressed air to remove dust and metal particles. Ensure the machine is unplugged before cleaning.
• Inspecció de torxes i cables: Inspect the MIG torch, electrode holder, ground clamp, and all cables for cuts, cracks, or loose connections before each use. Replace damaged parts immediately.
• Contact Tip and Nozzle: Replace worn contact tips and clean the welding nozzle regularly to prevent spatter buildup.
• Rodets d'accionament: Keep the drive rollers clean and free of debris to ensure smooth wire feeding. Check for wear and replace if necessary.
• Emmagatzematge: Guardeu el soldador en un entorn net i sec, allunyat de la pols i la humitat excessives.
