Una descàrrega elèctrica pot matar: Assegureu-vos d'una connexió a terra correcta. No toqueu les parts elèctriques actives. Porteu guants aïllants secs i roba protectora.
Els fums i els gasos poden ser perillosos: Keep your head out of the fumes. Use ventilation or exhaust to remove fumes and gases from the breathing zone.
Els raigs d'arc poden cremar els ulls i la pell: Wear a welding helmet with a proper shade filter. Wear appropriate eye protection with side shields. Protect exposed skin with appropriate protective clothing.
Perill d'incendi i explosió: Remove all flammables from the welding area. Have a fire extinguisher readily available.
Les parts calentes poden causar cremades greus: Allow equipment to cool before handling. Wear insulated gloves.
Cylinders Can Explode If Damaged: Secure cylinders properly. Keep cylinders away from heat and mechanical shock.

Consult your welding machine's manual for additional safety guidelines.

4. Configuració i instal·lació

Proper setup is crucial for safe and efficient operation. Refer to your welding power source manual for specific connection points.

Connecteu el cable d'alimentació: Attach the 25-foot braided power cable to the appropriate output terminal on your TIG welding power source. Ensure a secure, tight connection.
Connecteu les línies d'aigua: As this is a water-cooled kit, connect the water inlet and outlet lines from the torch to your water cooler unit. Ensure proper flow direction and leak-free connections.
Connectar la línia de gas: Attach the shielding gas hose from the torch to your gas regulator and cylinder. Verify all gas connections are tight to prevent leaks.
Install Torch Head: Select either the 9-70 head or the 1726 head based on your application requirements and securely attach it to the torch body.
Install Consumables: Insert the collet, collet body, tungsten electrode, and ceramic cup into the torch head. Ensure the tungsten is properly ground and extends the correct distance.
Comproveu si hi ha fuites: Before welding, activate the water cooler and gas flow to check for any leaks in the water or gas lines. Address any leaks immediately.

5. Instruccions de funcionament

This section outlines general operating procedures for TIG welding with the W-225MOD torch. Always refer to your welding power source manual for specific settings and procedures.

Preparació de la peça de treball: Clean the workpiece thoroughly to remove any contaminants, rust, or paint.
Set Welding Parameters: Ajusteu el amperage, gas flow rate, and post-flow time on your welding power source according to the material thickness and type, and tungsten size. The torch supports an output range of 225/200/160 Amp DC and 160/140/115 Amp AC (100% Duty Cycle).
Iniciar l'arc: Use either lift-arc or high-frequency (HF) start, depending on your power source capabilities, to initiate the welding arc.
Maintain Arc Length: Keep a consistent arc length, typically equal to the diameter of the tungsten electrode.
Add Filler Metal (if required): Introduce filler rod into the weld puddle as needed, maintaining a consistent feed rate.
Terminate Arc: Gradually reduce amperage at the end of the weld to prevent crater cracking. Allow the shielding gas to flow for the set post-flow time to protect the cooling weld and tungsten.

6. Manteniment

Regular maintenance ensures optimal performance and extends the life of your TIG torch kit.

Inspect Cables and Hoses: Regularly check the power cable, water lines, and gas hose for cuts, abrasions, or leaks. Replace damaged components immediately.
Clean Torch Body and Handle: Wipe down the torch body and handle to remove any spatter or debris.
Inspect Consumables: Check the collet, collet body, and ceramic cup for wear or damage. Replace as necessary. Ensure the tungsten electrode is clean and properly ground.
Water Cooler Maintenance: Follow the manufacturer's instructions for your water cooler, including checking coolant levels and cleaning the filter.
Emmagatzematge: Store the torch kit in a clean, dry environment when not in use to protect it from dust and damage.

7. Solució De Problemes

This section addresses common issues that may arise during TIG welding. For more complex problems, consult a qualified technician or your welding power source manual.

Problema	Causa possible	Solució
Poor Arc Start / Unstable Arc	Contaminated tungsten, incorrect tungsten grind, insufficient gas flow, poor ground connection.	Regrind tungsten, check gas flow and connections, clean workpiece and ground clamp.
Tungsten Contamination	Tungsten touching weld puddle, insufficient gas shielding, incorrect gas post-flow.	Maintain proper arc length, increase gas flow, extend post-flow time.
Porositat en soldadura	Inadequate gas shielding, gas leaks, contaminated workpiece, excessive gas flow.	Check gas connections for leaks, clean workpiece, adjust gas flow rate.
Torch Overheating	Insufficient water flow, clogged water lines, exceeding duty cycle.	Check water cooler operation and coolant level, inspect water lines for obstructions, reduce amperage or allow torch to cool.
