Quick-Change Gas Coupler for Weldcraft Torches

The Miller Electric CS310 is a quick-release gas coupler designed for TIG welding setups. It fits Weldcraft torch models including the WP-18, WP-20P, WP-24W and WP-25. The coupler accepts shielding gases such as argon, helium, carbon dioxide and nitrogen. It allows rapid connection and removal of gas hoses without tools.

Suited for TIG welders who swap torches frequently

This coupler serves operators who need fast gas-line changes between jobs or torch configurations. It is not intended for applications outside GTAW processes. Buyers who require a coupler for MIG or stick welding equipment should look at alternatives designed for those processes. The part is restricted from sale in California due to Proposition 65 chemical warnings.

Compatibility defined by Weldcraft series

The single specification that decides fitment is the torch series or model number. This CS310 couples with W-180, W-200, W-225, W-250, W-280, W-310, W-350, W-375, W-400 and W-410 series torches. It also matches CS310 and CS410 model designations. Verify the torch series before ordering.
