Are you curious to know what is lift TIG? You have come to the right place as I am going to tell you everything about lift TIG in a very simple explanation. Without further discussion let’s begin to know what is lift TIG?
Lift TIG is a welding technique that is commonly used in the welding industry. It is a variation of Tungsten Inert Gas (TIG) welding that is known for its precision, control, and cleanliness. In this blog, we will explore what Lift TIG is, how it works, and its advantages.
What Is Lift TIG?
Lift TIG is a welding technique that uses a non-consumable tungsten electrode to heat and melts the base metal, which is then joined together with a filler metal. The process uses a high-frequency starting circuit that provides an initial arc between the tungsten electrode and the base metal. Once the arc has been established, the tungsten electrode is slowly lifted away from the base metal, which results in a controlled arc that maintains the required heat input to complete the weld.
How Does Lift TIG Work?
Lift TIG works by creating an arc between a non-consumable tungsten electrode and the base metal, which melts the base metal and creates a pool of molten metal that can be joined together with a filler metal. The tungsten electrode is held in a torch, and the arc is initiated by a high-frequency starting circuit. Once the arc has been established, the tungsten electrode is slowly lifted away from the base metal until the required arc length is achieved. The filler metal is then introduced into the molten pool, and the welding process continues until the joint is complete.
Advantages Of Lift TIG
Lift TIG offers several advantages over other welding techniques. Firstly, it is known for its precision and control, which makes it ideal for welding applications that require a high degree of accuracy, such as aerospace and medical equipment. Additionally, Lift TIG produces clean welds that are free from contaminants, which makes it suitable for applications that require high-quality welds, such as food and beverage production. Finally, Lift TIG can be used on a wide range of metals, including aluminum, stainless steel, and copper alloys, which makes it a versatile welding technique.
Conclusion
In conclusion, Lift TIG is a welding technique that uses a non-consumable tungsten electrode to heat and melt the base metal, which is then joined together with a filler metal. The process is known for its precision, control, and cleanliness, making it a popular welding technique in various industries. By understanding how Lift TIG works and its advantages, welders and manufacturers can make informed decisions about which welding technique to use for their specific needs.

FAQ
What Is The Difference Between TIG And Lift TIG?
Therefore, a significant difference between lift TIG and scratch start is that with the lift TIG, you cannot stick the tungsten electrode to the metal. Since the initial current is low and only lets the machine know that you’ve touched the metal, it cannot melt the tungsten or the welded part.
What Is Lift TIG Welding Used For?
Lift TIG is best for welding steel (e.g. stainless steel). It isn’t good with aluminum due to a reaction between the metal and tungsten.
Does Lift TIG Need Gas?
Simply put, NO, you can’t TIG weld without Gas! Gas is required to protect both the Tungsten Electrode and the weld pool from Oxygen. Most TIG Welder torches are also cooled by the gas, so not using gas would risk burning out the Torch.
Can You Weld Aluminum With Lift TIG?
In order to weld aluminum, you can use an AC TIG welder or MIG welder with an aluminum spool gun. Yes, you can weld it with other processes like laser beam welding and stick welding using a special electrode for this metal and in other ways.
