Miller Weldcraft Nozzle Insulator PK2

This two-pack of white nozzle insulators is designed for TIG welding torches. It fits a wide range of Miller and Weldcraft torch models including the WP-9, WP-20, and WP-25 series. The insulators suit both gas lens and non-gas lens applications. They are essential consumables for maintaining proper gas coverage.

Compatible with multiple torch series

The insulators work with Series 20, 9, A-125, HW-20, HW-9, PTA-9, PTW-20, W-200, W-225, W-250, W-280, W-310, and W-375 torches. They also fit models such as 20F, 20HP, 20P, 9F, 9FVB, 9HP, 9P, 9V, 9VB, CS310A, HW-20R, HW-9F, HW-9R, PTA-9F, WP-20P, WP-20V, WP-9F, WP-9FV, WP-9V, WP-R9F, and WP-R9FV. This broad fit reduces the need to stock different insulator types.

Verify torch model before ordering

Check your torch model number against the compatible list to ensure correct fitment. These insulators are not suitable for torches outside the listed Miller and Weldcraft series. Confirm whether your setup uses a gas lens or standard collet body, as the insulator must match the nozzle configuration. The pack contains two units for routine replacement.

Does this insulator work with both gas-lens and standard collet bodies?

Yes, the 598882 nozzle insulator is compatible with both gas-lens and non-gas-lens configurations on the listed TIG torches.

How is the insulator installed on the torch head?

Remove the nozzle, slide the white insulator over the collet body or gas lens until it seats against the torch head, then reinstall the nozzle; the step often missed is ensuring the insulator sits flush before tightening the nozzle.
