There are two groups of TIG torches, air cooled and water cooled.
Air cooled TIG torches tend to be available for welding up to 200A. Above 200A, the torch can get hot and the torch components can degrade quicker due to the additional heat.
Water cooled TIG torches are generally used for welding above 200A where air cooled torches can get too hot to comfortably hold.

The torches may also come with a flexible neck and shielding gas control.
When buying TIG torch consumables, parts have to be compatible with the type of TIG torch you are using. Sometimes, this may not follow a logical pattern, so always check for compatible parts before purchasing. You can see in the table below, there are two distinctive groups, A & B.
