Annotated photograph of the stand-alone weld monitor with laser aiming. The purposes of the various connectors are indicated. The stand-alone monitor's flexibility is suitable for test and evaluation or research and development applications where flexibility in pointing or change in optics is required. A photograph of the monitor is shown in Figure 1 . The reproducibility of the monitor's signal output will depend on the accuracy and repeatability in aiming.
Laser aiming that comes with the monitor offers the best overall accuracy and ease.
Costs can be reduced further with conventional gunsights with loss in accuracy and ease. The reproducibility of the monitor's output will depend on the field of view, the aiming method and the capability to manually aim and lock in position. In practice, even with laser aiming, the accuracy will be compromised by the mechanical system used to allow for aiming adjustments. Improved reproducibility can be obtained at the expense of time taken to aim accurately. The integrated version of the monitor is recommended for process operations.
