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. Like, you need to select a quality TIG welder that could weld different types of metals. You should also select a device effective at working with different types of compressed gas.

1. Match the metal type you want to weld to the electrical input of the TIG welder. Like, 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 want 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 want to weld thick metals, you need a welder effective at producing high amperages (amp). Low amperage welders produce 165 to 200 amps while high-amperage welders produce 310 to 700 amps.
