What does TIG welding mean?

TIG – Tungsten Inert Gas – welding is an arc welding process when the welder makes an arc between the base metal and non-consumable tungsten electrode. This is a type of electrode that doesn’t melt. TIG welding uses a constant current welding power supply in order to obtain an electric arc between the tungsten electrode and the workpiece, utilizing the resultant to form the weld. TIG welding is perfect for projects which require an excellent dexterity, namely, for projects where curves or detailed designs are needed on the base metal. Here are some details ofTIG welding

AC/DC output

The metal you’re going to weld has actually to determine your choice. Considering the fact that there are two principal modes of TIG welding, you must identify the nature of the metal and the mode you will use. Don’t forget that DC (Direct Current) is commonly used for all metals except aluminium and magnesium alloys. AC (Alternating Current) is good only for aluminium and magnesium alloys.

Basic or sophisticated welding

Of course, the price of high-tech professional TIG welders and small hobby-type ones will vary.

Machine size

Think about the location you will use the welder. If you’re going to use it beyond your workshop, it would be better to pick out more portable welding machine to reach maximum comfort. If it’s mostly for indoor use, portability isn’t so crucial.

Duty cycle

The duty cycle of a welder is an indicator that shows how long you can weld without worrying about overheating the machine. The duty cycle is the time that a welder can operate at maximum output and it’s usually expressed as a percentage. In most cases, 40-60% is an adequate choice.
