How To Choose A High Quality TIG Welder
Choosing a quality TIG welder requires that you familiarize yourself with several if the technical aspects of this type of tool. For example, you need to select a quality TIG welder that can weld different types of metals. You should also select a machine capable of working with different types of compressed gas.

1. Match the metal type you want to weld to the electrical input of the TIG welder. For example, if you need a welder capable of welding hard metals like bronze, cast iron or steel, an alternating current welder should work. AC welders operate using electricity that alternates direction back and forth. If you need to weld soft metals like aluminum you need a direct current welder. Direct current electricity creates a steady arc for the welder and comes from battery cells.

2. Decide on thickness of the metal that you need to weld. If you need to weld thick metals, you need a welder capable of producing high amperages (amp). Low amperage welders produce 165 to 200 amps while high-amperage welders produce 310 to 700 amps.
