OVERVIEW

Master Your TIG Welding with ESAB

Take your welding projects to the next level with the ESAB SR 400 TIG Torch, a powerhouse built for serious welders. If you are pushing high amps and need a torch that can keep up without overheating, this water-cooled beast is your answer. Rated for a massive 400 amps, it allows you to weld continuously on heavy plate without stopping to let the torch cool down. The water-cooling technology actively pulls heat away from the front end, protecting your consumables and keeping your hand cool even on the hottest jobs.

Freedom of movement is essential in any shop, and the SR 400 delivers with a 25-foot (8-meter) lead. This extra length means you can work on large assemblies, trailers, or pipe racks without constantly dragging your welder across the floor. The cable itself is designed to be flexible and tough, resisting cuts and burns while staying light enough to maneuver easily into tight corners. The OKC50 connector makes setup a breeze—just plug it in, twist to lock, and you are ready to arc up with a solid, reliable connection.

Comfort matters when you are under the hood all day. ESAB has designed the SR 400 with an ergonomic handle that feels great in your hand. The grip is designed to prevent slipping and reduce the hand fatigue that often comes with heavy TIG torches. This means you can maintain a steady hand and lay down perfect beads for longer. Upgrade your rig with the ESAB SR 400 and experience the difference that professional-grade equipment makes in your weld quality and daily comfort.

FAQ

The ESAB SR 400 is a water-cooled TIG torch, designed for high-amperage applications.

It is rated for 400 Amps DC at 100% duty cycle.

This torch is equipped with an OKC50 (Dinse-style 50mm) connector.

The cable assembly is 25 feet (8 meters) long.

Yes, because it is a water-cooled torch, a recirculating water cooler is required to prevent overheating and damage.

It can be used with any machine that supports a water-cooled torch and has a compatible OKC50 connection, though adapters may be required for gas/water lines depending on the specific machine setup.

It typically uses standard SR/WP style consumables compatible with 18/26/400 series torches, including collets, collet bodies, and gas lenses.

Typically, high-amperage water-cooled torches like the SR 400 do not have a manual gas valve on the handle; gas flow is controlled by the welding machine's solenoid.
