2. Configuración
2.1 Conexión de alimentación
- The MIG-135PLUS operates on a 220V/230V power supply. Ensure your power source matches this requirement.
- Connect the power cord securely to a grounded electrical outlet.
2.2 Wire Installation (Flux-Cored MIG)
- Abra o compartimento de alimentación do fío.
- Place the flux-cored wire spool onto the spindle, ensuring it rotates freely.
- Thread the wire through the guide tube and into the drive rollers.
- Close the drive roller tension arm and adjust the tension. The wire should feed smoothly without slipping or deforming.
- Feed the wire through the MIG torch liner until it exits the contact tip.
- The welder supports 0.030'' (0.8mm) and 0.035'' (0.9mm) flux-cored wires.
2.3 Conexión de accesorios
- Antorcha MIG: Connect the MIG torch cable to the corresponding port on the front panel.
- Cl Claseamp: Conecte a terra clamp cable to the negative (-) terminal. Attach the clamp securely to the workpiece, ensuring good electrical contact.
- Electrode Holder (for MMA): Connect the electrode holder cable to the positive (+) terminal for MMA welding.
- Lift TIG Torch (Optional): If using a Lift TIG torch (not included), connect it to the appropriate port as per its instructions.

3. Modos de funcionamento
3.1 4-in-1 Welding Functions
The MIG-135PLUS offers four versatile welding processes:
- Gasless Flux-Cored MIG: Ideal for outdoor use and welding mild steel without the need for shielding gas. Includes a pulsed function for smoother, more stable arcs and finer weld beads.
- Standard Gasless MIG: Basic flux-cored MIG welding.
- Levante TIG: For precise welding of various metals (requires a separate Lift TIG torch, not included).
- Soldadura por electrodo revestido (MMA): For welding with coated electrodes, suitable for thicker materials. Features adjustable Hot Start and Arc Force.

3.2 Panel de control e pantalla
The welder features a precise 4.1-inch LED digital display that provides real-time welding data such as voltage, current, and wire feed speed. This display is protected by a transparent cover for durability against impacts and splashes.
3.3 Welding Mode Selection (SYNERGIC vs. Manual)
- SYNERGIC Mode (Automatic): Recommended for beginners. The system automatically adjusts voltage based on the wire feed speed, simplifying parameter setup.
- Modo manual: Recommended for experienced users. Allows separate and precise control over welding current and voltage for fine-tuning.

3.4 2T/4T Trigger Modes
- 2T Mode (Two-Touch): Press and hold the torch trigger to start wire feeding and welding. Release the trigger to stop. Suitable for short welds.
- 4T Mode (Four-Touch): Press the trigger once to start wire feeding and welding. Press it again to stop. Ideal for longer welds, reducing hand fatigue.

3.5 Pulsed MIG Welding (Gasless)
The gasless MIG function includes a pulsed mode, which provides a smoother and more stable arc. This results in finer, more uniform weld beads and stronger joints, enhancing the quality and versatility of gasless welding.

4. Mantemento
Un mantemento regular garante a lonxevidade e o rendemento óptimo da súa máquina de soldar.
- Limpeza: Periodically clean the machine's exterior with a dry cloth. Use compressed air to clear dust from ventilation openings.
- Tocha e cables: Inspeccione a tocha MIG, o portaelectrodos e a conexión de terra.amp cables for any signs of damage, cuts, or loose connections. Replace damaged components immediately.
- Mecanismo de alimentación de arame: Keep the wire feed rollers clean and free of debris. Ensure the wire liner is not clogged.
- Almacenamento: Garde a soldadora nun ambiente seco e limpo, lonxe de po e humidade excesivos.
5 Solución de problemas
The MIG-135PLUS features an advanced protection system against overcurrent, overload, overheating, and overvoltage. If an issue occurs, the machine may automatically shut down or display an error code. Consult the table below for common issues.
| Problema | Causa posible | Solución |
|---|---|---|
| Sen arco / Arco débil | Poor ground connection, incorrect settings, damaged torch/cable, power supply issue. | Comprobar chan clamp connection. Verify welding parameters. Inspect cables and torch. Ensure stable power supply. |
| Wire feed issues | Incorrect drive roller tension, clogged liner, wrong wire size, spool tangled. | Adjust drive roller tension. Clean wire liner. Ensure correct wire size for rollers. Untangle spool. |
| Protección contra sobrecalentamento activada | Ciclo de traballo superado, mala ventilación. | Allow the machine to cool down. Ensure proper ventilation around the unit. Reduce welding time. |
| Mala calidade da soldadura | Incorrect settings (voltage, wire speed), improper technique, contaminated workpiece. | Adjust welding parameters. Practice proper welding technique. Clean workpiece thoroughly. |
