How To Choose A High Quality TIG Welder
Selecting a quality TIG welder requires that you familiarize yourself with several if the technical facets of this kind of tool. Like, you'll need to pick an excellent TIG welder that could weld various kinds of metals. It's also wise to select a device effective at dealing with various kinds of compressed gas.

1. Match the metal type you wish to weld to the electrical input of the TIG welder. Like, if you will 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 will need a direct current welder. Direct current electricity creates a constant arc for the welder and originates from battery cells.

2. Choose thickness of the metal that you'll require to weld. If you want to weld thick metals, you will 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.
