2.5. Arc sensing monitoring
(1) Monitoring execution
If you select ‘26: Arc sensing data’ among monitoring items, arc sensing monitoring will be executed.
This item is activated only when the arc sensing license is valid.
(2) Description of the monitoring items
Figure 2.6 Detailed description of the arc sensing monitoring window
l Left / Right following: Indicates the following speed and distance through the sensing in the left and right directions as well as the left and right compensation distances calculated based on the current difference method
l Up / Down following: Indicates the following speed and distance through the sensing in the up and down directions as well as the left and right compensation distances calculated based the welding line method
l XYZ following: Indicates the distance followed up to now compared with the original trajectory, in the X, Y and Z directions of the base coordinates.
l Sensing data
BC: The sensing reference current in the up and down directions
CC: The current at the center of the current section for the sensing in the up and down directions
LR: Current at the end range of the current section
WC: Welding current of the welder
Mode: Delay time and mode number that are currently applied
The reference current in the up and down direction should be set as a value acquired by averaging the values of the current at the center, along a certain section, of the welding start range.
When it comes to the sensing in the up and down directions, the compensation distance in the up and down directions should be calculated based on the difference between the reference current and the measured current. When the reference current is increased, the torch and base material will get closer and, when the reference current is lowered, the torch and base material will get distant.
l Weaving data: Indicates the current weaving width, the weaving frequency, the delay time and the mode number.
l Multipass: Indicates the current / entire count of the stored multipass data as well as the shift distance and angle.
