This unit comes with a simplified teaching screen that is dedicated to welding and easy operation as standard. The system conducts welding like a skilled human welder. The teach pendant is even equipped with an easy-to-view, easy-to-operate touch-screen. The system comes equipped standard with a dedicated start sequence function that improves the arc start ratio, as well as a restart sequence function that sends the robot back to the point where welding was interrupted and automatically conducts overlapped welding, thereby restarting the welding operation. The system incorporates a range of innovations, developed from the design phase to cope with noise generation in TIG welding, plasma cutting, etc., so it can be operated without about having to worry about noise-related constraints.
