Questions about this item

Does the 13N21 collet generate heat or noise during extended TIG welding sessions?

The collet itself is a passive metal component; it conducts welding current but produces no noise and its temperature follows the torch duty cycle.

Which TIG torch models must I already own for the 13N21 collet to fit?

It fits WP-9, WP-9F, WP-9V, WP-9FV, WP-R9F, WP-R9FV, WP-20, WP-20P, WP-20V, WP-25 and the 9, 20, 25 series torches listed in the compatibility data.

Will the 13N21 collet work with my older WP-9 torch that uses a gas lens?

Yes, the collet is compatible with both gas-lens and non-gas-lens configurations on the WP-9 and other listed torch models.
