What is lift tig?

Lift TIG, also known as TIG lift start or scratch start TIG welding, is a manual arc welding process that uses a non-consumable tungsten electrode to produce the weld. In lift TIG welding, the welding torch is brought into contact with the workpiece, and then lifted slightly to initiate the arc.

This method is commonly used for welding thin materials, as it provides a precise and consistent arc start without the need for high-frequency starting equipment. Lift TIG welding is often used for welding stainless steel, aluminum, and other non-ferrous metals.

One advantage of lift TIG welding is that it allows for better control over the weld pool and heat input, resulting in high-quality welds with minimal distortion. It also produces a cleaner and more precise weld compared to other welding methods.

Overall, lift TIG welding is a versatile and efficient process that is commonly used in industries such as aerospace, automotive, and fabrication.
