Unleash Your Creativity with the Square Wave TIG 200

Whether you are a seasoned welding veteran or a hobbyist looking to expand your skills, the Lincoln Electric Square Wave TIG 200 is designed to grow with you. This machine proves that simplicity does not have to mean compromise. The user-friendly interface allows you to "set it and forget it," making setup incredibly fast so you can focus on the arc. It is the perfect machine for motorsports enthusiasts, aviation hobbyists, and creative makers who demand precision without the complexity of industrial menu systems.

Master Aluminum Welding

Aluminum is often considered the holy grail of TIG welding, and the Square Wave TIG 200 makes it accessible. With dedicated AC TIG functionality, you can produce beautiful, stacked-dime welds on aluminum parts. The machine features adjustable AC Frequency and AC Balance, giving you the power to tailor the arc to your specific joint configuration. Need a wider bead for a fillet weld? Lower the frequency. Need to punch into a corner? Increase it. These tools help you become a better welder faster.

Versatility for Every Project

The Square Wave TIG 200 is a true multi-process machine. While it excels at precision TIG welding, it also includes a robust Stick welding mode. This is ideal for heavy-duty repairs on trailers, fences, or farm equipment where shielding gas isn't practical. The Dual Voltage input (120V/230V) means you are never limited by your power source—plug it in anywhere and start welding. The included Pulse feature is a game-changer for learning heat control, acting as a training aid that helps time your dips and manage puddle fluidity.
