What to Know Before Buying
Before investing in the Lincoln Square Wave TIG 200, it’s essential to consider its limitations. While suitable for most DIY jobs, the machine has some drawbacks, including limited TIG functions, lack of shielding gas output control, and the absence of a memory function. Understanding these limitations is crucial to avoid buyer’s remorse.
Limited TIG Functions: While the Lincoln Square Wave TIG 200 supports advanced TIG functions, such as pulsed TIG, AC balance, and AC frequency settings, its limitations become apparent in the restricted adjustability of these features. Pulsed TIG, for instance, is capped at 20 pulses per second, potentially limiting its effectiveness for certain applications.
No Shielding Gas Output Control: Despite having a pre and post-flow gas feature, the Lincoln Square Wave TIG 200 lacks adjustable settings. Many welders in its range offer more flexibility in shielding gas control, allowing for precise adjustments and gas conservation.
No Memory Function: The absence of a memory function is a notable drawback, especially for professional welders or those handling multiple projects. This feature streamlines the welding process by enabling users to store and recall specific parameters, reducing setup time and minimizing the risk of errors.
Best Features
Despite its limitations, the Lincoln Square Wave TIG 200 boasts several commendable features:
Arc Quality: The arc quality is a standout feature, with stability and smoothness synonymous with reputable brands like Lincoln.
Build Quality: Designed for hobbyists and light fabrication, the machine exhibits a sturdy build with a premium feel. The large, infinitely adjustable knob enhances the user experience, and the included flex-head TIG torch facilitates access to tight spots.
Advanced TIG Functions: The Lincoln Square Wave TIG 200 supports AC TIG, AC/DC TIG Pulse, AC Frequency, and AC Balance, providing versatility for various welding applications.
VRD Support: The inclusion of Voltage Reduction Device (VRD) is an advanced safety feature that lowers the open circuit voltage when the welder is idle, minimizing the risk of electric shocks.
