Miller Syncrowave 400 AC/DC TIG Welder Package with Wireless Pedal

Master Precision with the Syncrowave 400

Take your TIG welding to the next level with the Miller Syncrowave 400 Complete Package, a machine built to make your workday smoother and your welds cleaner. If you have ever struggled with cable management around large workpieces, you will appreciate the included Wireless Foot Control. It gives you the responsiveness you expect from a Miller pedal without the restriction of a cord, improving safety and letting you weld comfortably in any position. This machine is designed to be the workhorse of your shop, handling everything from delicate aluminum structures to heavy steel pipe with ease.

The Syncrowave 400 takes the guesswork out of machine setup. With the Pro-Set feature, you can instantly access professional-grade settings for Pulse, Frequency, and Balance with the touch of a button. This means you spend less time fiddling with knobs and more time laying beads. The arc stability is exceptional; Blue Lightning high-frequency starting ensures consistent, non-contact starts every time, while the expanded AC frequency control lets you focus the arc for tight corners or widen it for smooth fill passes. Whether you are training new welders or are a seasoned pro, the intuitive interface makes it easy to get the perfect arc immediately.

Comfort and efficiency are built into the design. The machine is significantly lighter and smaller than older industrial TIG units, freeing up valuable floor space. The Coolmate 3S cooling system keeps your W-375 torch cool even during long welds at high amperage, preventing hand fatigue and equipment overheating. With the ability to plug into almost any shop power (single or three-phase) automatically via Auto-Link, the Syncrowave 400 is as versatile as it is powerful. This complete package arrives with everything you need—just add gas and wire—to start fabricating immediately.
