Understanding the Unimig TIG Welder
What is a TIG Welder?
In the world of welding, TIG welding, also known as Tungsten Inert Gas welding, is renowned for its ability to produce high-quality welds with great precision. Unlike MIG (Metal Inert Gas) welding, which uses a consumable wire as an electrode, TIG welding employs a non-consumable tungsten electrode. This gives the welder maximum control over the arc and heat input, making it the preferred method for welding thinner materials and where aesthetics matter, such as in artistic and automotive applications.
The method involves striking an arc between the tungsten electrode and the workpiece, while an inert shielding gas, typically Argon, protects the weld pool from atmospheric contamination. As a result, TIG welding produces clean and strong welds, minimizing the risk of defects such as porosity and cracking. The versatility of TIG welding makes it suitable for a wide range of metals including steel, aluminum, and even exotic materials like magnesium.
