A TIG (Tungsten Inert Gas) welding machine, also known as a GTAW (Gas Tungsten Arc Welding) machine, uses a non-consumable tungsten electrode to weld metals. This process needs a shielding gas, like argon, to protect the weld from contamination.

TIG welding is highly valued for its precision, making it ideal for industries like aerospace, automotive, and medical, as well as for artistic welding projects. It can handle various metals, including stainless steel, aluminum, copper, and titanium.

TIG welding machines range from small, portable units for hobbyists to larger, industrial models for heavy-duty work. They require a skilled hand due to the need for precise control over the welding arc and filler material. Many models come with advanced settings like adjustable amperage, pulse frequency, and waveform to fine-tune the welding process for high-quality results.

Overall, TIG welding machines are a top choice for professional welders who need precision, versatility, and the ability to produce clean, high-quality welds across different metals.
