Tig Welders: FAQ

How do I ensure the welder fits my power setup?

Always verify the voltage requirements (110V vs 220V) in the product description. Many global models offer dual-voltage auto-switching, ensuring compatibility with your local workshop outlets without needing transformers.

Can these machines actually weld aluminum?

Look specifically for 'AC/DC' capabilities if you plan to weld aluminum. DC-only machines are limited to steel and stainless, so checking the output current type is vital for material compatibility.

What technical specs indicate a high-quality machine?

Check the 'Duty Cycle' percentage; a 60% duty cycle at maximum amperage indicates a robust cooling system. High-quality units also feature IGBT inverter technology for stable arc performance and longevity.

Are these heavy machines safe to ship internationally?

Sellers on AliExpress typically use reinforced foam packaging for heavy equipment. Look for listings with 'Choice' shipping or 'Local Warehouse' options to minimize transit time and ensure better handling.

Recommendations for buyers

✓
IGBT Inverter Technology
Prioritize machines using IGBT technology over older MOSFET systems for better energy efficiency, a more stable arc, and a significantly lighter machine body.
✓
Pulse Functionality
Select a machine with pulse TIG settings to control heat input. This is essential for preventing burn-through on thin stainless steel and producing aesthetic 'stack of dimes' welds.
✓
High-Frequency (HF) Start
Ensure the unit has HF Start to initiate the arc without touching the tungsten to the workpiece, which prevents contamination and extends the life of your electrodes.
✓
Amperage Control Options
Check for a 5-pin or 7-pin connector if you require a foot pedal. Real-time amperage control is crucial for managing the weld pool on varying material thicknesses.
