Miller Electric Auto Axcess 675 manual Robot Auto-Calibration Sample Programs

4-6. Robot Auto-Calibration Sample Programs

.It is critical to make certain that NO start power, start conditions, run-in, or crater parameters of any kind are present in the robot program. The welding power source is looking for 2 distinct welding conditions. If there is a “start power” condition, the welding power source will equate this as the first condition and fail to execute Auto-Cal correctly. If there is a “crater fill” condition, the welding power source will equate this as the second condition and fail to execute Auto-Cal correctly.
