I. Introduction

A. Background of TIG Welding

Tungsten Inert Gas (TIG) welding, or Gas Tungsten Arc Welding (GTAW), is a versatile and precise welding method. It utilizes a non-consumable tungsten electrode to deliver the current to the welding arc, with the welded area shielded from atmospheric contamination by an inert shielding gas. TIG welding offers greater control and is primarily used for thin sections of stainless steel non-ferrous metals like aluminum, copper alloys, and magnesium.

B. Importance of Choosing the Right Welder

Selecting the right TIG welder is crucial to achieving the desired results. The right equipment ensures efficiency, quality, and safety. Factors like amperage range, duty cycle, and the machine’s features significantly impact the welding process and outcome. With numerous options available in the market, understanding the features and performance of a welder becomes imperative.
