• Since this condition is applicable only to this vehicle (J11), never apply it to welding conditions of
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.
• If carbon dioxide gas (CO2 100%) is used for shielding gas of welder, adequate weld strength cannot
be secured. For this reason, always use fuel mixture for shielding gas of welder to prevent.
• When welding hole diameter cannot be satisfied, make multiple holes (smaller diameter) so that the
sum of hole areas becomes equal to the area of the specified weld hole.
EXAMPLE
Chip tip diameter
6 mm
Welding pressure
3100 N
Welding current
7900 A
Weld time
