INSTALLATION\n\nSPOT WELD POINTS\nWhen welding panels with a combined thickness of over 3 mm (0.12 in.), use a MIG (Metal Inert Gas) welder for plug welding.\nHINT: spot welding will not provide sufficient durability for panels over 3 mm (0.12 in.) thick.\nLess than 3 mm\n\nAPPLICATION OF WELD–THROUGH PRIMER (SPOT SEALER)\nRemove the paint from the portion of the new parts and body to be welded, and apply weld–through primer.\nHINT: See \"ANTI–RUST TREATMENT\" on page AR–2.\n\nWRONG\n\nAir Saw\n\n20 – 30 mm\nOverlap\n\nPuncher\n\nROUGH CUTTING OF JOINTS\nFor joint areas, rough cut the new parts, leaving 20 – 30 mm (0.79 – 1.18 in.) overlap.\n\nMAKING HOLES FOR PLUG WELDING\nFor areas where a spot welder cannot be used, use a puncher or drill to make holes for plug welding.\nREFERENCE:                    mm (in.)\n\nThickness of welded portion | Size of plug hole\n1.0 (0.04) under | 5 (0.20) φ over\n1.0 (0.04) – 1.5 (0.06) | 6.5 (0.26) φ over\n1.5 (0.06) over |
