How To Choose A High Quality TIG Welder
Picking a quality TIG welder requires that you familiarize yourself with several if the technical areas of this sort of tool. Like, you will need to choose a good TIG welder that could weld several types of metals. It's also advisable to select a device effective at working together with several types of compressed gas.

1. Match the metal type you intend to weld to the electrical input of the TIG welder. Like, if you'll 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'll need a direct current welder. Direct current electricity creates a regular arc for the welder and arises from battery cells.

2. Determine thickness of the metal that you might want to weld. If you want to weld thick metals, you'll 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.
