2. Información de seguridade
Welding operations involve significant risks. Always prioritize safety to prevent injury or damage. Read and understand all safety warnings and instructions before operating this equipment.
Precaucións xerais de seguridade:
- Equipos de protección individual (EPI): Use sempre o EPI axeitado, incluíndo un casco de soldador con sombra axeitada, roupa resistente ás lapas, luvas de soldador e calzado de seguridade.
- Ventilación: Ensure adequate ventilation to remove welding fumes and gases, which can be hazardous to health.
- Prevención de incendios: Keep a fire extinguisher nearby. Remove all flammable materials from the welding area. Be aware of sparks and hot slag.
- Seguridade eléctrica: Ensure the welding machine is properly grounded. Do not operate in wet conditions. Inspect cables and connections for damage before each use.
- Protección ocular e cutánea: Welding arc rays can cause severe burns to eyes and skin. Never look at the welding arc without proper eye protection.
- Área de traballo: Keep the work area clean, dry, and free of clutter. Ensure stable footing.
- Nenos e espectadores: Manteña os nenos e o persoal non autorizado lonxe da zona de soldadura.
O VRD (Voltage Reduction Device) function is designed to reduce the open-circuit voltage to a safe level when the machine is not actively welding, minimizing the risk of electric shock. Always ensure this feature is active unless specific welding conditions require its deactivation (refer to operating instructions).

4. Configuración
Proper setup is crucial for safe and effective welding. Follow these steps before beginning any welding task.
4.1 Conexión de alimentación:
- Ensure the welding machine's power switch is in the OFF position.
- Connect the input power cable to a grounded 230V AC power outlet. Verify that the power supply meets the machine's requirements.
4.2 Connecting Welding Cables:
- Cl Claseamp: Conecte a terra clamp cable to the Negative Output Terminal (-) on the front panel. Securely attach the ground clamp á peza de traballo ou a unha parte metálica limpa e espida da mesa de soldadura, garantindo un bo contacto eléctrico.
- Electrode Holder (for MMA): Connect the electrode holder cable to the Positive Output Terminal (+) on the front panel.
- Soplete TIG (para Lift TIG): For Lift TIG welding, connect your TIG torch (not included) to the Positive Output Terminal (+). Ensure the TIG torch has a gas valve for manual gas control.
Always ensure all connections are tight and secure before powering on the machine.
5. Instrucións de funcionamento
This section details the operation of the YESWELDER ARC-125D PRO for both MMA and Lift TIG welding modes.
5.1 MMA (Stick) Welding:
- Encendido: Turn on the welding machine using the Power Switch. The LED display will illuminate.
- Selecciona o modo MMA: Press the MODE button until "Stick" or "MMA" is indicated on the digital display.
- Inserir eléctrodo: Securely insert the appropriate electrode (e.g., E6011, E6013, E6010, E7018 up to 3.18mm) into the electrode holder.
- Axustar a corrente: Use the Value Knob to set the desired welding current (Amperage) based on the electrode type and material thickness.
- Adjust Parameters (Optional): Press the PARAM button to cycle through Hot Start and Arc Force settings. Use the Value Knob to adjust these values as needed for optimal arc ignition and stability.
- VRD Function: Ensure the VRD is ON for maximum safety, especially in damp environments or when working at height.
- Comezar a soldar: 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.

5.2 Soldadura TIG por elevación:
For Lift TIG welding, a TIG torch with a gas valve and a separate gas cylinder (Argon) are required (not included).
- Encendido: Acenda a máquina de soldar.
- Select Lift TIG Mode: Press the MODE button until "Lift TIG" is indicated on the digital display.
- Conectar a tocha TIG: Ensure your TIG torch is connected to the Positive Output Terminal (+) and the gas hose is connected to your Argon gas cylinder.
- Prepare Tungsten Electrode: Instale un eléctrodo de tungsteno afiado na soplete TIG.
- Axustar a corrente: Use the Value Knob to set the desired welding current.
- Abrir a válvula de gas: Open the gas valve on the TIG torch to establish gas flow.
- Initiate Arc (Lift Arc): Gently touch the tungsten electrode to the workpiece. A small current will flow. Slowly lift the torch to establish the arc. The machine will automatically increase the current to the set value.
- Realizar soldadura: Manteña unha lonxitude de arco consistente e alimente a varilla de recheo manualmente se é necesario.
- Terminate Arc: To stop welding, simply lift the torch away from the workpiece. Close the gas valve on the TIG torch after welding.
