INTRODUCTION IN-12 PREPARATION FOR INSTALLATION SPOT WELD POINTS APPLICATION OF WELD-THROUGH PRIMER (SPOT SEALER) Remove the paint from the portion of the new parts and body to be welded, and apply weld-through primer. HINT: See ”ANTIRUST TREATMENT”’ on page AR-2 . When welding panels with a combined thickness of over 3 mm (0.12 in.), use a MIG (Metal Inert Gas) welder for plug welding. HINT: Spot welding will not provide sufficient durability for panels over 3 mm (0.12 in.) thick. 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 damaged by the electrical current flowing through the body. Before starting work disconnect the negative terminal of the bat- tery 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 - 1.18 in.) 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:
