Esab 10N21 Tig Torch Collet 0.5mm HW17 HW18 HW26

Product Description

The ESAB 10N21 is a 0.5mm TIG torch collet designed to secure the tungsten electrode inside compatible TIG torch bodies during gas tungsten arc welding operations. The collet provides precise electrode centering and reliable clamping, which directly affects arc stability and weld quality. At 0.01 pounds, it is a lightweight consumable component that must be replaced periodically as part of routine torch maintenance. Licensed welding professionals and skilled tradespeople typically handle collet replacement during torch service.

This collet is suited for light-duty TIG welding applications where a 0.5mm tungsten electrode diameter is required. It is commonly used in precision welding scenarios such as thin-gauge sheet metal, instrumentation work, and fine fabrication. The small electrode size makes this collet appropriate for low-amperage work where tight arc control is critical. It is packaged individually and sold in multiples of five per order.

Key Features

• 0.5mm bore diameter sized for fine-gauge tungsten electrodes
• Industry-standard part number 10N21 for straightforward cross-referencing
• Compatible with HW17, HW18, and HW26 TIG torch bodies
• Lightweight consumable at 0.01 pounds for minimal torch weight impact
• Sold individually with a minimum order quantity of 5 units

Compatibility

The ESAB 10N21 collet is compatible with HW17, HW18, and HW26 TIG torch bodies as stated by the manufacturer.

Installation Notes

Collet replacement is performed by qualified welders or welding equipment technicians. Always disconnect the torch from the power source and allow all components to cool fully before disassembling the torch head. Remove the back cap, electrode, and collet body before replacing the collet, then reassemble in reverse order and verify electrode stick-out before resuming welding operations. Do not overtighten the back cap, as this can deform the collet and affect electrode clamping.
