2. Precaucions de seguretat
Always prioritize safety when operating welding and cutting equipment. Failure to follow these guidelines can result in serious injury or death.
- Seguretat elèctrica: Ensure the machine is properly grounded. Do not operate in wet conditions. Always disconnect power before performing maintenance or changing accessories.
- Protecció ocular i facial: Always wear a welding helmet with appropriate shade lenses and safety glasses with side shields.
- Protecció corporal: Wear flame-resistant clothing, welding gloves, and protective footwear. Avoid loose clothing.
- Ventilació: Ensure adequate ventilation to remove welding fumes and gases, which can be hazardous to your health.
- Prevenció d'incendis: Keep a fire extinguisher nearby. Remove all flammable materials from the work area. Welding sparks can travel.
- Cilindres de gas: Secure gas cylinders properly to prevent tipping. Handle with care and ensure connections are leak-free.
- Superfícies calentes: Welding equipment and materials become extremely hot. Allow them to cool before handling.

3. Configuració i connexions
Before operating the HBMC270, ensure all connections are secure and correct for the desired welding or cutting process.
- Connexió d'alimentació: Connect the machine to a stable 220V power supply. Ensure the power outlet is rated for the machine's current draw.
- Terra Clamp: Enganxa el terra clamp cable to the appropriate terminal on the machine (usually marked "-" or "EARTH"). Securely attach the clamp a la peça de treball o a una part metàl·lica neta i nua de la taula de soldadura.
- Connexió de la torxa MIG: For MIG welding, connect the MIG torch to the designated MIG output terminal. Install the appropriate wire spool and feed the wire through the torch liner.
- Connexió de la torxa TIG: For HF TIG welding, connect the TIG torch to the TIG output terminal. If using gas, connect the gas hose from the torch to the gas regulator on the machine.
- Plasma Cutting Torch Connection: For plasma cutting, connect the plasma torch to the CUT output terminal. Connect the air hose from the torch to the air regulator on the machine and ensure a compressed air supply is connected.
- Electrode Holder (Stick/MMA): For Stick welding, connect the electrode holder cable to the appropriate terminal (usually marked "+" or "MMA").
- Gas Supply (for Gas MIG/TIG/Plasma): Connect the gas regulator to your shielding gas cylinder (e.g., CO2, Argon, or Argon/CO2 mix for MIG; Argon for TIG). Connect the gas hose from the regulator to the machine's gas inlet. For plasma cutting, connect the air compressor to the machine's air inlet.

4. Instruccions de funcionament
The HBMC270 offers multiple welding and cutting processes. Select the desired mode and adjust parameters using the intuitive LED display.
4.1. Synergy Mode & LED Display
The large LED display provides clear feedback on parameters. In Synergy (SYN) mode, the machine intelligently auto-matches voltage and current based on selected electrode size, metal thickness, and welding mode, simplifying setup for beginners.
- Seleccioneu el mode SYN: Press the mode button to activate synergy.
- Seleccioneu el material: Choose the type of material you are welding (e.g., Fe+CO2, Fe+MIX, FLUX, AL+Ar).
- Selecciona la mida del cable: Input the diameter of your welding wire.
- The machine will suggest optimal voltage and current settings. Fine-tune as needed.

4.2. Welding and Cutting Processes
The HBMC270 supports the following processes:
- MIG (Gas/Sense gas): For general fabrication, auto repair, and home projects. Supports .023"/.030"/.035"/.039" solid/flux core wires and .039" aluminum wire.
- HF TIG: High-frequency arc ignition for precise welding of aluminum, magnesium alloys, thin plates, and titanium alloys.
- Plasma Cutter: Capable of cutting quality 12mm (1/2") and maximum 18mm (2/3") thickness.
- Pal (MMA): For welding thicker materials and outdoor repairs. Supports 6011, 6013, and 7018 welding rods (1/16"-1/8").
- Soldadura per punts: Ideal for metal sheet and automated welding applications.

4.3. Funció 2T/4T
- 2T (Dos tocs): Press and hold the trigger to weld, release to stop. Suitable for short welds and tacking.
- 4T (Quatre tocs): Press and release the trigger to start welding, press and release again to stop. Ideal for long, continuous welds, reducing operator fatigue.
5. Manteniment
Regular maintenance ensures the longevity and optimal performance of your HBMC270 welder.
- Neteja: Periodically clean the machine's exterior with a dry cloth. Use compressed air to blow out dust and debris from cooling vents.
- Consumables Check: Regularly inspect and replace worn-out MIG contact tips, nozzles, TIG collets, electrodes, and plasma cutting tips/electrodes.
- Sistema d'alimentació de filferro: Clean the wire feed rollers and check the wire liner for blockages or wear. Ensure proper tension on the wire feed rollers.
- Terra Clamp & Cables: Inspect all cables for cuts, fraying, or damage. Ensure the ground clamp makes good contact with the workpiece.
- Air Filter (Plasma Cutter): If applicable, clean or replace the air filter for the plasma cutting system to ensure clean air supply.
