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.

Jeremy McGrath, a Supercross racer making the transition to off-road truck racing, recently set up a state-of-the-art motorsports welding shop geared toward component builds and repair work. If you’re setting up a motorsports welding and fabrication shop for the first time, there are some vital pieces of equipment that will help you be successful. It’s important to remember that you don’t have to be a renowned off-road truck racer to have a professional-grade motorsports fabrication shop.

Aluminum has garnered a reputation for being difficult to weld, especially when using gas tungsten arc welding (GTAW). Mastering the process isn’t as daunting as you might think. All you really need for successful aluminum GTAW is an understanding of the metal’s unique properties and the welding preparation techniques and tools you’ll need to address those properties.
Plasma arc welding (PAW) uses plasma, a gas that has been heated to a high temperature and ionized. The plasma becomes electrically conductive, transferring an electric arc to the workpiece through a small orifice.
