(Water-cooled)

Formerly known as WP-18SC

Water-cooled torch designed to endure some of the most

demanding applications while minimizing overheating.

Extend torch and consumable life with the full-flow water chamber

that provides around-the-head cooling.

Improve gas coverage and cooling capacity with gas lens usage with

heavy-duty stubby collet body.

Extend parts life using the durable copper components, maximizing

current capacity.

Applications

Weldcraft W-410 (Water-cooled)

™

Formerly known as CS410

Water-cooled torch that increases amperage output

without increasing torch size. Designed for demanding

applications.

D-Handle™ design features a self-indexing flat top that allows for

torch orientation by feel.

Work in cold weather with the Tri-Flex™ hose and cable assembly

that remains flexible to ease handling and extends cable life.

Improve high-frequency shielding and minimize gas leakages with

the double-lip back cap seal.
