ThePasspassnumber is displayed on the left center of the screen. To change the pass being viewed, use the joy- stick to highlight the pass number and then joystick left or right to change the pass number. For pipe, the infor- mation is displayed in a similar manner on a 2D screen as though the pipe is unraveled and put on a flat sur- face. The user can choose between viewing the whole pipe or one of the four quadrants of the pipe. Use the joystick to highlight the pipe section desired.
TheraveltravelDirectidirectionnis located on the right side in the middle of the screen. When the user first starts to weld, a travel direction is sensed by the system and an arrow indicating the direction is displayed. For visual cues, the system assumes these directions. The visu- al cues will automatically adapt to the travel direction used when the arc is struck.
