OVERVIEW

Upgrade to Industrial Power with the W-400 Super Cool Kit

When your welding projects demand high heat and long arc times, standard torches just can't keep up. Enter the Miller Weldcraft W-400 Super Cool TIG Torch Kit, the ultimate upgrade for professional welders who refuse to compromise on performance. Formerly the legendary WP-18SC, the W-400 is built to stay cool under pressure, handling a massive 400 amps of DC output at a 100% duty cycle. This means you can weld continuously without stopping to let your torch cool down, maximizing your productivity on heavy aluminum or thick steel sections.

Comfort and control are at the heart of the W-400's design. The torch features a specially textured handle that provides a secure, non-slip grip, giving you the precision needed for intricate aerospace work or critical pipe welds. The water-cooling system is engineered with a unique full-flow chamber that wraps around the head, preventing the uncomfortable heat buildup that plagues lesser torches. This "Super Cool" technology not only protects your hands but also drastically extends the lifespan of your collets, bodies, and nozzles, saving you money on consumables in the long run.

Miller has taken the guesswork out of upgrading your rig by packaging this torch as a complete, ready-to-weld kit. Forget about hunting for the right adapter or wondering which regulator fits; the 300186 kit includes it all. You get a premium Smith flowmeter, a heavy-duty ground clamp with cable, protective cable covers, and a starter pack of consumables. Whether you are outfitting a new Dynasty 700 or upgrading a Syncrowave, this kit provides the reliability and heavy-duty performance required for shipbuilding, construction, and precision metal art. It is the perfect all-in-one solution for the serious fabricator.
