Welders are judged by the appearance of their beads, the strength of their welds, and their ability to pass visual and technical inspection. So why shouldn’t you scrutinize your GTAW torch components in the same way that you or someone else would scrutinize your welds? If your GTAW torch doesn’t pass inspection, there’s a good chance that your welds won’t either.
