• The below welding condition is applicable only to this vehicle. Never apply this same welding condi-
tion to other vehicles.
Welding condition
PLUG WELDING
To weld ultra high strength steel of tensile strength 980 MPa or more, perform plug welding observing the
welding hole diameter described in the manual.
CAUTION:
• To perform plug welding, use fuel mixture (Ar 80% + CO2 20%) for shielding gas of welder.
• Never use carbon dioxide gas (CO2 100%) as shielding gas of welder. Using CO2 100% gas results in
inadequate weld strength.
• When welding hole diameter cannot be met, make multiple holes (smaller diameter) so that the sum
of the hole areas equals the area of the original weld hole.
