- Selector de mode: Switch between MMA (Coated Electrode), FLUX (Flux Core), and LIFT TIG (TIG Lift Arc) welding modes.
- Corrent / Voltage Ajust: Dial to set the welding current for MMA/TIG or voltage for Flux Core.
- Wire Speed Adjustment: Dial to control the wire feed speed for Flux Core welding.
- Indicadors: Power, Overheat, and Welding Mode indicators.
5. Configuració
5.1 Connexió d'alimentació
- Assegureu-vos que l'interruptor d'alimentació de la màquina de soldar estigui en la posició OFF.
- Connect the power cable to a suitable AC power outlet (230V). The machine is suitable for use with generators, tolerating +/-15% for MIG/TIG and AC 210V - 264V for MMA.
5.2 Flux Core Welding Setup
- Open the side panel to access the wire feeder compartment.
- Install a flux-cored wire spool (up to 1kg, 0.8mm to 1.0mm diameter, e.g., 0.9mm E71T-GS) onto the spindle.
- Thread the wire through the feeder mechanism and into the integrated torch liner.
- Connecteu la terra clamp a la peça de treball, garantint un bon contacte elèctric.

5.3 MMA (Coated Electrode) Welding Setup
- Connect the electrode cable with its clamp to the positive (+) terminal on the front panel.
- Connect the ground cable with its clamp al terminal negatiu (-) del panell frontal.
- Securely insert the desired coated electrode (up to Ø 3.2mm, suitable for Rutile, Stainless Steel, Cast Iron, Cellulosic) into the electrode holder.
- Connecteu la terra clamp a la peça de treball.
5.4 TIG Lift Arc Welding Setup
- Connect the TIG torch (not included, but the integrated torch is for MIG/Flux) to the negative (-) terminal. The product description mentions an integrated torch for versatility, but TIG Lift Arc typically uses a separate TIG torch. For TIG Lift Arc, the TIG torch must go to the negative terminal.
- Connect the ground cable with its clamp al terminal positiu (+).
- Install a tungsten electrode (maximum 2.0mm diameter) into the TIG torch.
- If using inert gas (e.g., Argon), connect the gas hose from the regulator to the TIG torch.
- Connecteu la terra clamp a la peça de treball.
6. Instruccions de funcionament
6.1 Flux Core Welding (FCAW)
- Engegueu la màquina de soldar.
- Select the 'FLUX' mode on the control panel.
- Ajusteu el voltage and wire speed according to the wire diameter and material thickness. Start with recommended settings and fine-tune as needed. The machine offers adjustable wire speed with current and voltage, up to 120A and 11m/min.
- Position the integrated torch at the start of the weld joint.
- Press the trigger on the torch to start welding. Maintain a consistent travel speed and arc length.
6.2 MMA (Coated Electrode) Welding
- Engegueu la màquina de soldar.
- Select the 'MMA' mode on the control panel.
- Adjust the current (Amperage) based on the electrode type and diameter, and the material thickness. The machine supports electrodes from 1.6mm to 3.2mm.
- Strike the arc by lightly touching the electrode to the workpiece and quickly lifting it slightly to establish the arc.
- Maintain a consistent arc length and travel speed to create a uniform weld bead.

Figura 4: Example of MMA (Coated Electrode) welding in action.
6.3 TIG Lift Arc Welding
- Engegueu la màquina de soldar.
- Select the 'LIFT TIG' mode on the control panel.
- Adjust the current (Amperage) based on the tungsten electrode diameter and material thickness. The machine supports tungsten electrodes up to 2.0mm.
- Initiate the arc by gently touching the tungsten electrode to the workpiece and then lifting it slightly. The arc will ignite without high-frequency start.
- Maintain a short arc length and feed filler rod (if required) into the weld puddle.

7. Manteniment
Regular maintenance ensures the longevity and optimal performance of your welding equipment.
- Neteja: Periodically clean the machine's exterior with a dry, soft cloth. Use compressed air to blow out dust from inside the machine, especially from cooling vents, ensuring the power is disconnected first.
- Inspecció del cable: Regularly inspect all cables (power, ground, electrode, torch) for cuts, fraying, or damage. Replace damaged cables immediately.
- Manteniment de la torxa: For Flux Core, regularly check and clean the contact tip and nozzle. For TIG, ensure the tungsten electrode is sharp and free of contamination.
- Emmagatzematge: Store the welding machine in a clean, dry environment, protected from dust and moisture.
