High-frequency (HF) arc start enables non-contact initiation of the arc, which prevents tungsten contamination and results in cleaner, more precise welds. This feature is especially important when welding aluminum or for applications where weld quality is critical. Models like the Lincoln Aspect 230 AC/DC TIG Welder and Lincoln Sprinter 180Si Case and TIG One-Pak offer high-frequency start, making them excellent choices for high-quality, precision work. Many welders now include HF start, so you can select a machine that matches your quality requirements.
