[Cause]
When the electrode tips contacted, contact did not occur at the specified contact speed. The applied force may deviate from the adjusted applied force. For the following reasons, the pressure application start position cannot be secured sufficiently and contact speed cannot be compensated.
- The opening amount in the specified SD condition is too small.
- The taught position is incorrect.
- The gun mastering position is incorrect.
- The thickness is incorrect.
[Countermeasure]
Check the gun opening amount before pressure application. Adjust mastering, taught position and thickness appropriately.
