2. Informació de seguretat
Welding can be hazardous. Always follow safety precautions to prevent injury or damage. Keep this manual for future reference.
2.1 Precaucions generals de seguretat
- Descàrrega elèctrica: Pot matar. No toqueu les parts elèctriques actives. Porteu guants de soldadura secs i roba de protecció. Assegureu-vos que la zona de treball estigui seca.
- Fums i gasos: Pot ser perillós per a la salut. Mantingueu el cap allunyat dels fums. Utilitzeu la ventilació o l'extracció per eliminar els fums de la zona de respiració.
- Raigs d'arc: Can burn eyes and skin. Wear a welding helmet with a proper shade filter. Wear safety glasses with side shields. Wear protective clothing.
- Incendi i explosió: Welding sparks can cause fire or explosion. Keep combustibles away from the welding area. Have a fire extinguisher nearby.
- Parts calentes: Can cause severe burns. Allow equipment to cool before touching. Wear insulated gloves.
- Soroll: El soroll excessiu pot danyar l'oïda. Feu servir protecció auditiva.
- Àrea de treball: Mantingueu la zona de treball neta, ben il·luminada i lliure de trastos. Assegureu-vos una ventilació adequada.
2.2 Thermal Overload Protection
The Mastercraft Mig and Flux Welder is equipped with thermal overload protection. If the unit overheats, the protection system will activate, and a light indicator will illuminate. Allow the welder to cool down before resuming operation. Do not bypass this safety feature.

4. Configuració
Una configuració adequada és crucial per a una soldadura segura i eficaç.
4.1 Desembalatge i inspecció
- Traieu amb cura tots els components de l'embalatge.
- Inspect the welder and all accessories for any signs of damage. Do not operate if damaged.
- Assegureu-vos que tots els components enumerats siguin presents.
4.2 Connexió d'alimentació
Connect the welder to a suitable power supply as specified in the electrical requirements section of this manual. Ensure the power outlet is properly grounded.
4.3 Instal·lació de la bobina de filferro
The welder features a 2-in-1 spool holder compatible with both 4" (10 cm) and 8" (20 cm) wire spools.
- Obriu el panell lateral de la soldadora.
- Col·loqueu el carret de filferro al portacarrets, assegurant-vos que giri lliurement.
- Introduïu el filferro de soldadura a través del tub guia i dins del mecanisme del rodet impulsor.
- Secure the wire with the tension arm, adjusting tension as needed (refer to the drive deck diagram).

4.4 Polarity Control (MIG vs. Flux-Cored)
The Mastercraft Mig and Flux Welder allows for quick and easy polarity changes, which is essential when switching between MIG (Gas Metal Arc Welding) and Flux-Cored Arc Welding (FCAW).
- MIG Welding (with gas): Typically requires DC Electrode Positive (DCEP), meaning the welding torch is connected to the positive terminal and the ground clamp to the negative.
- Flux-Cored Welding (without gas): Often requires DC Electrode Negative (DCEN), meaning the welding torch is connected to the negative terminal and the ground clamp to the positive.
Refer to the polarity diagram inside the welder's wire compartment for specific connections.
Figura 4.2: This image shows the internal compartment with the wire spool holder and a clear diagram indicating the correct polarity settings for 'No Gas' (Flux-Cored) and 'Gas' (MIG) welding.
4.5 Gas Connection (for MIG Welding)
If performing MIG welding, connect your shielding gas cylinder and regulator to the gas inlet on the welder. Ensure all connections are secure and leak-free.
5. Instruccions de funcionament
Once setup is complete, you can begin welding. Always wear appropriate personal protective equipment (PPE).
5.1 Controlsview
- Interruptor d'alimentació: Turns the welder ON/OFF.
- Selecció de calor: Four settings to adjust welding heat for different material thicknesses and applications.
- Wire Speed Control: Infinite adjustment knob to control the rate at which the welding wire is fed.
- Thermal Overload Indicator: Illuminates if the unit overheats.
5.2 Welding Procedure
- Preparació de la peça de treball: Clean the metal surface thoroughly, removing rust, paint, and grease.
- Connecteu la terra Clamp: Fixeu fermament el clavill de terraamp to the workpiece or a clean, bare metal work table.
- Seleccioneu Configuració: Adjust the heat setting and wire speed according to the material type and thickness. Start with recommended settings and fine-tune as needed.
- Position Torch: Hold the welding torch at the correct angle (typically 10-15 degrees from vertical) and distance from the workpiece.
- Iniciar l'arc: Press the trigger on the welding torch to start the wire feed and initiate the arc.
- Soldar: Maintain a consistent travel speed and arc length to create a uniform weld bead.
