WATER-COOLED

TIG Torches

Weldcraft W-350 Series (Water-cooled)

™

Formerly known as WP-18 Series

Rugged water-cooled torches

engineered for high-amperage and

continuous hand-held welding in

mechanized applications.

Reduce downtime and costs by minimizing

overheating with the unique cooling design

engineered for operator comfort.

Reduce discomfort and fatigue using the

comfortable handle design.

Superior gas flow control offered through the

built-in fingertip gas control (W-350 Valve).

Weldcraft W-400 Super Cool

Applications

™

(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.

Rated Output

DC: 400 A at 100% duty cycle

AC: 280 A at 100% duty cycle

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.
