Nov 12, 2007Previously, Bohannon and his crew chief Gary Hunter were using an oxyacetylene process to weld the mostly aluminum body of the Exxon Flyin' Tiger, but recently have made the switch to a TIG process and Lincoln's Invertec&V205-T AC/DC. "TIG offers much higher quality, less corrosion and a strong weld," noted Bohannon.
