Informació de seguretat
Always prioritize safety when operating welding and cutting equipment. Failure to follow safety precautions can result in serious injury or death. Read and understand all safety warnings and instructions before use.
- Equips de protecció individual (EPI): Utilitzeu sempre l'EPI adequat, com ara un casc de soldadura amb la ombra adequada, roba ignífuga, guants de soldadura i calçat de seguretat.
- Ventilació: Ensure adequate ventilation to remove welding fumes and gases, which can be hazardous to your health.
- Seguretat elèctrica: Comproveu el vol correctetage (110V/220V) and ensure proper grounding. Do not operate in wet conditions.
- Prevenció d'incendis: Keep a fire extinguisher nearby. Remove flammable materials from the work area. Welding sparks can travel.
- Raigs d'arc: Protegiu els ulls i la pell dels raigs d'arc, que poden causar cremades i lesions oculars.
- Cilindres de gas comprimit: Handle gas cylinders with care. Secure them properly to prevent tipping.

Configuració
Connexió d'alimentació
The MF160PRO supports dual voltage input (110V/220V). Use the appropriate adapter and ensure the power source matches the machine's requirements.

Figure 5: The MF160PRO is compatible with both 110V and 220V power supplies using the included adapter.
Accessoris de connexió
Connect the appropriate torch, work clamp, and gas hose (if applicable) according to the welding/cutting process you intend to use. Refer to the "Welding Polarity" section for correct terminal connections.
Instruccions de funcionament
The MF160PRO offers five distinct operating modes. Select the desired mode using the Menu Choose Button and adjust parameters with the respective knobs.
Polaritat de soldadura
Correct polarity is crucial for optimal welding and cutting performance. Refer to the diagram below for proper connections for each mode.

Figure 6: Polarity connections for different welding and cutting processes.
- MIG (Gas MIG): DCEP (elèctrode de corrent continu positiu)
- FCAW (Flux Core MIG): DCEN (Direct Current Electrode Negative)
- TIG (HF TIG): DCEN (Direct Current Electrode Negative)
- BASTÓ (MMA): DCEP (elèctrode de corrent continu positiu)
- CUT (Plasma Cutting): DCEP (elèctrode de corrent continu positiu)
MIG Welding (Gas MIG / Flux Core MIG)
The MF160PRO features SYNERGIC MIG control, which automatically matches recommended current and wire feeding speed based on wire diameter and gas material selection. This simplifies operation, especially for beginners.
- MIG amb gas: Requires shielding gas (e.g., Argon/CO2 mix for steel). Connect gas hose to the machine and cylinder.
- MIG amb nucli de flux (MIG sense gas): Uses flux-cored wire, no external shielding gas required. Ensure correct polarity (DCEN).
- Instal·lació de cable: Install the appropriate welding wire spool and feed the wire through the torch liner.
- Ajust de paràmetres: Select MIG mode. Use the voltage and current knobs to fine-tune settings if not using synergic control, or to override synergic suggestions.
HF TIG Welding
High Frequency (HF) start TIG provides non-contact arc initiation, reducing tungsten and material consumption and offering a cleaner start compared to Lift TIG. Ideal for precise welding of low-carbon steel or stainless steel.
- Connexió de gas: Requires shielding gas (e.g., 100% Argon). Connect gas hose.
- Elèctrode de tungstè: Install a sharpened tungsten electrode into the TIG torch.
- Preflux/Postflux: The machine is equipped with pre-flow/post-flow functions to protect the weld puddle and tungsten.
- Ajust de paràmetres: Select TIG mode and adjust current.
MMA (Stick) Welding
MMA welding is suitable for various materials and outdoor conditions. Connect the electrode holder and work clamp according to the polarity requirements of your electrode type.
- Selecció d'elèctrodes: Choose the appropriate electrode for your material and application.
- Ajust de paràmetres: Select MMA mode and adjust current based on electrode diameter and material thickness.
Plasma Cutting (CUT)
The plasma cutter offers powerful cutting ability, with an 8mm ideal clean cut and 12mm maximum severance cut under 220V. It uses non-hazardous compressed air to cut various metals.
- Compressor d'aire: Connect a suitable air compressor to the air filter regulator on the machine. Ensure clean, dry air supply.
- Consumibles: Ensure correct plasma torch consumables (electrode, nozzle, shield cup) are installed.
- Compatibilitat de materials: Capable of cutting stainless steel, alloy steel, mild steel, copper, and aluminum.
- Ajust de paràmetres: Select CUT mode and adjust current.
