Misfires are one of the most frustrating parts of welding—everything’s lined up perfectly, you pull the trigger, and nothing happens. For welders working with delicate materials or low energy settings, inconsistent arc ignition can feel unavoidable. But it doesn’t have to be. Sunstone’s Tru-Fire Technology® changes the game by ensuring every weld starts cleanly and predictably. By actively managing ignition, Tru-Fire delivers a controlled, consistent pulse at the exact moment of contact—eliminating hesitation, wasted time, and costly errors. With Tru-Fire, welders experience smoother workflow, cleaner welds, and total confidence in every spark.

In the world of modern welding, precision and reliability aren’t optional—they’re essential. With pulse arc welding—also called TIG welding—success comes down to how well your welder controls energy delivery. Too much energy generates excess heat and equipment wear, while too...
