4. Configuració
4.1. Connexió d'alimentació
- Ensure the welder's power switch is in the OFF position.
- Determine your power source: 110V or 220V. The machine automatically detects the voltage.
- If using a 110V outlet, connect the provided 110V-220V adapter cord to the welder's power cable, then plug into the wall outlet.
- If using a 220V outlet, connect the welder's power cable directly to the 220V outlet.
- Assegureu-vos que la presa de corrent estigui correctament connectada a terra.

4.2. Connexió dels cables de soldadura
The AZZUNO Mini Stick Welder uses standard DINSE connectors for welding cables.
- Terra Clamp: Connecteu la terra clamp cable to the negative (-) terminal on the front panel. Twist clockwise to secure. Attach the earth clamp fermament a la peça o a la taula de soldadura, garantint un bon contacte elèctric.
- Portaelèctrode (MMA): For MMA welding, connect the electrode holder cable to the positive (+) terminal on the front panel. Twist clockwise to secure. Insert the welding electrode into the holder.
- Lift TIG Torch (Optional): For Lift TIG welding, connect the TIG torch cable to the negative (-) terminal. Twist clockwise to secure. (Note: The Lift TIG torch is not included and must be purchased separately.)

5. Instruccions de funcionament
5.1. Engegada i selecció de mode
- After connecting power and welding cables, turn on the main power switch located on the rear of the machine.
- The digital display will light up.
- Press the 'Mode Choose Button' on the front panel to select between MMA (Stick) or Lift TIG welding. The corresponding LED will illuminate.

5.2. Adjusting Welding Current
Use the 'Current Knob' to adjust the welding amperage. The digital display will show the selected current. Refer to electrode manufacturer specifications or welding charts for appropriate current settings based on electrode type and material thickness.
5.3. Soldadura amb electrodo enrotllat (MMA)
This mode is suitable for welding with various types of electrodes, including E6011, E6013, and E7018, for material thicknesses up to 13/64" (5mm).
- Ensure the electrode holder is connected to the positive (+) terminal and the earth clamp to the negative (-) terminal (DCEP).
- Seleccioneu el mode MMA.
- Set the appropriate welding current.
- Strike the arc by lightly touching the electrode to the workpiece and quickly lifting it slightly to establish the arc. The built-in Hot Start feature assists with arc ignition.
- Maintain a consistent arc length and travel speed. ARC Force helps maintain arc stability, and Anti Stick prevents the electrode from fusing to the workpiece.
