Collet holder 2.4 30mm /701.1289-ZVAR/ TIG17/18/26 with strainer

The pincer holder has four holes on the sides through which the welding gas flows. Depending on whether the gas is further directed by a screen or not, there are two types of holders:

· collet holder with a screen, called a gas lens - the screen evenly distributes the gas and helps to achieve higher quality welds (same principle as with a screen on a tap). Without a screen, the water swirls a little, with a screen it flows gently, dispersed - the same applies to a collet holder with a screen and welding gas.

· standard collet holder - gas flows directly through the holes and creates slight turbulence.
