WENA style spray tip for the Lawson pre-treat sprayer machines.
Here are some general principles to understand:
- When using this with an air operated Zoom, Zoom-XL, or Zoom-Pro, Set your Air-Pressure to at least 50 psi. The amount of psi will effect the uniformity and amount of fluid deposit. You will determine the “ideal” pressure setting for your particular environment and type of printing through “trial-and-error”.
- The Height of the Spray Head will effect the spray width you achieve. The higher the Nozzle from the substrate the wider the spray width.
- Note: Daily Purging of the System is critical to consistent spraying. The Nozzle/Tip can start to spray more narrowly as the edges become encrusted with salt deposits from the pre-treat solution.
