INTRODUCTION - General Repair Instructions IN-12 PREPARATION FOR INSTALLATION SPOT WELD POINTS APPLICATION OF WELD-THROUGH PRIMER (SPOT SEALER) When welding panels with a combined thickness of over 3 mm (0.12in.), use a MIG (Metal Inert Gas) welder for plug welding. HINT: Spot welding will not provide sufficient durability for panels over 3 mm (0.12in.) thick. Remove the paint from the portion of the new parts and body to be welded, and apply weld- through primer. HINT: See ”ANTI- RUST TREATMENT” on page AR-2. Less than 3 mm The above SSM or equivalent Air Saw 20 - 30 mm Puncher Overlap SAFETY PRECAUTIONS FOR ELECTRICAL COMPONENTS.
When welding there is a danger that electrical components will be dam- aged by the electrical current flow- ing through the body. Before starting work disconnect the negative terminal of the battery and ground the welder near the welding location of the body. ROUGH CUTTING OF JOINTS For joint areas, rough cut the new parts, leaving 20 - 30 mm (0.79 - 1.18in.) overlap. MAKING HOLES FOR PLUG WELDING For areas where a spot welder cannot be used, use a puncher or drill to make holes for plug welding. REFERENCE:
