Quick-Release Coupler for TIG Torches

The Miller Enterprises CS310 is a quick-connect water hose coupler designed for TIG welding (GTAW) systems. It enables fast attachment and removal of coolant hoses on compatible torches. The coupler suits workshops that change torches frequently or need to service cooling lines without tools. It is built for use with Weldcraft-brand equipment.

Replaces Threaded or Clamped Hose Fittings

This coupler replaces traditional threaded or clamped coolant connections on supported torches. The upgrade is worth it when operators swap between multiple torch models during a shift or when maintenance intervals demand rapid hose detachment. It fits Series W-180 through W-410 torches and models including CS310, CS410, WP-18, WP-20P, WP-24W, WP-25 and WP-280SC. Buyers who need a permanent, non-quick-release connection will not benefit from this design.

Stays Sealed Under Continuous Coolant Flow

The coupler maintains a secure seal while coolant circulates during extended welding cycles. Its quick-release mechanism resists accidental disconnection caused by hose movement or vibration on the bench. The construction tolerates the temperatures and pressures found in standard TIG water-cooling circuits. Workshops that run high-flow or elevated-pressure cooling systems beyond typical TIG specifications should verify compatibility before installation.

Questions about this item

Which torch series does the CS310 quick-release water coupler fit?

The coupler is compatible with W-180, W-200, W-225, W-250, W-280, W-310, W-350, W-375, W-400 and W-410 series torches.

How do you install the quick-connect water hose coupler on a TIG torch, and what step is often missed?

Push the coupler onto the torch coolant hose until it clicks; the step often missed is verifying the locking collar has fully seated to prevent leaks.

When should the quick-release water coupler be replaced during regular TIG welding maintenance?

Replace the coupler if the locking mechanism no longer engages securely, if coolant leaks appear at the connection, or if the hose ends show cracking or deformation.
