Why You'll Love the Square Wave 205

Welding aluminum can be tricky, but the Square Wave 205 makes it accessible. With dedicated AC TIG mode, you get full control over your weld puddle. The adjustable AC Balance lets you clean the oxide layer effectively, while the Pulse feature helps prevent burn-through on thin sheet metal. It’s perfect for custom car parts, fixing aluminum boats, or creative metal art. Plus, if you need to switch to Stick welding for a quick repair on a trailer or fence, this machine handles 6010 and 7018 rods with ease.

Easy Setup, Professional Results

Gone are the days of guessing your settings. The large color LCD screen walks you through the setup process, making it easy to dial in the perfect amperage and settings for your material thickness. You don't need to be a master welder to get a great arc start—the high-frequency start ensures a clean ignition every time without touching the tungsten to the work.

Ready to Weld Out of the Box

The Lincoln Square Wave 205 comes as a complete package. You get the Caliber 17 TIG torch, a high-quality foot pedal for precise heat control, a gas regulator, and all the necessary cables. With the ability to plug into both 120V and 230V power, you can weld anywhere there's an outlet. At only 36 lbs, you can easily toss it in your truck or move it around your shop without breaking a sweat.
