Electrode collets for ST17 / ST26 TIG torches (3 units)
Tungsten held firmly and well centred, for a precise TIG arc. Kit of 3 electrode collets for ST17 and ST26 TIG torches. The collet holds the tungsten electrode and transfers the current to it.
A worn collet, or one of the wrong size, lets the electrode move, overheat or become contaminated. Choose the size of your electrode: 1.6, 2.0, 2.4 or 3.2 mm, and pair it with a collet body of the same size.
✅ Key benefits
Firm grip: the electrode does not slip while welding.
Good electrical contact: stable current transfer to the tungsten.
Four sizes: from 1.6 to 3.2 mm.
Pack of 3: spares for many working days.
🏗️ What it is for
ST17 and ST26 TIG torches.
TIG welding of steel, stainless steel and aluminium.
Changing electrode diameter.
TIG torch maintenance in the workshop.
📋 Technical specifications
Part: TIG electrode collet
Contents: 3 collets
Sizes: 1.6 · 2.0 · 2.4 · 3.2 mm
Compatibility: ST17 and ST26 TIG torches
How to choose the size
The collet must match the electrode diameter and the collet body. If you switch from a 1.6 mm to a 2.4 mm electrode, change the collet and collet body to 2.4 mm as well.
TIG torch maintenance
When changing the electrode, clean the collet and collet body and check the ceramic nozzle. A collet that is heat-distorted or dirty does not transfer current properly and makes the tungsten overheat. Keep a set of collets, collet bodies and nozzles to hand for each electrode diameter you use.
💡 Vetonek tip: always use a collet and collet body of the same size as the electrode: if they do not match, the tungsten moves, becomes contaminated and the arc turns unstable. Keep a set of each size you use regularly.
