Key Features and Benefits

The ESAB ET 200i AC/DC TIG welder comes packed with features that cater to both experienced welders and beginners. Let's break down some of the most important ones:

• AC/DC Functionality: This is a big one. Being able to switch between AC and DC modes means you can weld a broader range of materials. AC is ideal for aluminum, while DC is perfect for steel, stainless steel, and copper.
• Adjustable AC Balance: When welding aluminum, controlling the AC balance is crucial. This feature allows you to adjust the amount of time the current spends in the electrode negative (EN) and electrode positive (EP) phases. Adjusting the AC balance helps in controlling the cleaning action and penetration, resulting in cleaner and stronger welds on aluminum.
• Pulse Welding: The pulse function is incredibly useful for controlling heat input. By pulsing the welding current, you can reduce the risk of burn-through, especially on thinner materials. It also helps in achieving a more aesthetically pleasing weld bead.
• Digital Display and Controls: The digital display makes it easy to set and monitor welding parameters. Precise control over amperage, voltage, and other settings ensures consistent and repeatable results.
• Post-Flow Control: This feature allows you to control the amount of shielding gas that flows after the welding arc is extinguished. Post-flow is essential for protecting the weld from oxidation as it cools, ensuring a clean and strong weld.
• Overload Protection: Safety is always a priority. The built-in overload protection helps prevent damage to the machine in case of excessive current or voltage.
• Compact and Portable: Despite its robust capabilities, the ET 200i is relatively compact and easy to transport. This makes it a great option for both in-shop and on-site welding jobs.

These features combine to make the ESAB ET 200i AC/DC TIG welder a powerful and versatile tool for any welding project. The ability to fine-tune settings and handle various materials ensures high-quality results every time.
