Collet holder 3.2 21mm /TE0003-32/13N29/525.2453.2/701.0278-ZVAR/ TIG/9/20

Plate holder (plate house) - if the holder contains a strainer, it is called a gas lens. The key is inserted into the key holder. The clamp holder must be selected according to the size of the burner. The 9/20 collet holder is compatible for small TIG9 and TIG20 torches, while the 17/18/26 holder is for large TIG17/18/26 torches.

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.
