5. Configuració

Proper setup is crucial for safe and effective welding. Follow these steps for initial machine configuration.

5.1 Connexió d'alimentació

The LOTOS TIG200ACDC supports dual voltage input (110/120V or 220/240V). Use the appropriate power cord and converter pigtail for your power source.

• Assegureu-vos que l'interruptor d'alimentació del soldador estigui en la posició OFF.
• Connect the main power cable to the welder.
• If using 110/120V, attach the 220V/110V converter pigtail to the main power cable, then plug into a suitable outlet.
• If using 220/240V, plug the main power cable directly into a suitable outlet.
• Verifiqueu que la font d'alimentació compleixi els requisits del soldador.

5.2 Gas Connection (TIG Welding)

For TIG welding, an inert gas (Argon) is required.

• Attach the argon regulator to your argon gas cylinder.
• Connecteu la mànega de gas del regulador a l'entrada de gas a la part posterior de la soldadora.
• Assegureu-vos que totes les connexions estiguin ben ajustades per evitar fuites de gas.

5.3 Torch and Clamp Connexió

• Connect the TIG torch or MMA/Stick clamp to the appropriate terminals on the front panel.
• Connecteu la terra clamp to the workpiece. Ensure a clean, secure connection for optimal performance.
• If using the foot pedal, connect it to the designated port on the front panel.

6. Instruccions de funcionament

This section details the operation of the LOTOS TIG200ACDC for both TIG and Stick/MMA welding modes.

6.1 TIG Welding

• Select the TIG mode on the control panel.
• Choose between AC (for aluminum) or DC (for stainless steel, mild steel) based on the material.
• Ajusteu el amperage using the main amperage knob or the foot pedal.
• Set Pre-Flow and Post-Flow times to ensure proper gas shielding before and after welding.
• Adjust Clearance Effect for AC TIG welding to control arc cleaning action on aluminum.
• Initiate the arc using the HF start on the torch.

6.2 Soldadura amb electrod enrotllable/MMA

• Select the MMA mode on the control panel.
• Ensure the machine is set to DC output.
• Connect the MMA/Stick clamp and ground clamp.
• Ajusteu el amperage according to the electrode type and material thickness.
• The adjustable Hot Striking Arc Current feature assists in easier arc initiation.

6.3 Control Panel Settings

The control panel allows for fine-tuning of welding parameters:

• Ampera (A): Controls the welding current (10-200A).
• Pre-Flow: Sets the duration of gas flow before arc ignition (0.1s - 1s).
• Clearance Effect: Adjusts the balance between cleaning and penetration during AC TIG welding (-5 to +5).
• Downslope: Controls the time it takes for the current to decrease after releasing the trigger (1s - 10s).
• Postflux: Sets the duration of gas flow after the arc extinguishes (2s - 8s).

7. Manteniment

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

• Neteja: Periodically clean the exterior of the machine and ensure cooling vents are free from dust and debris. Use compressed air to clear internal components if necessary, ensuring the machine is unplugged.
• Inspecció del cable: Regularly inspect all cables, connections, and the TIG torch/MMA clamp for wear, damage, or loose connections. Replace damaged components immediately.
• Consumibles: Replace TIG torch consumables (tungsten electrodes, collets, ceramic cups) as they wear out to maintain weld quality.
• Regulador de gas: Check the argon regulator for proper function and leaks.

8. Solució De Problemes

If you encounter issues with your welder, refer to the following common troubleshooting steps:

• Sense energia: Check power connections, circuit breaker, and ensure the power switch on the welder is ON. Verify correct voltage entrada.
• Sense arc: Assegureu-vos que el sòl clamp is securely attached to the workpiece. Check torch connections and consumables. For TIG, verify gas flow.
• Mala qualitat de la soldadura: Ajustar amperage, gas flow, and travel speed. Inspect consumables for wear. Ensure the workpiece is clean.
• Amperage Knob Not Responding (with foot pedal): If the foot pedal is connected, it may override the panel amperage knob. Disconnect the foot pedal if you intend to use the panel knob for amperage control.
• Sobreescalfament: Allow the machine to cool down. Ensure cooling vents are clear and the duty cycle is not exceeded.
