Material Spraying Issues

It’s less common when material will not spray on the ‘A’ side and ‘B’ side at the same time, but when it happens, there could be a number of factors at play. If you find yourself in this position, take a look at these common reasons;

  4. Your regulator could be malfunctioning; Are you getting enough air supply to your Transfer Pump?
  5. Failing packings from wear or neglect.
  6. Clogged screens can also cause major issues in proper flow.
  7. Recent crossover in hose or contamination within the gun itself.

I recommended rechecking all of the electrical connections at least once every three months. Weak connections can prematurely short circuit or shorten the life of the electrical components.

When you suspect that you may have an electrical issue and need to contact a tech for help, one of the first things you may be asked is to confirm voltage’s through the spray system. Having a Multi-Meter on hand in your spray rig will help you to easily determine the answers you need to get your system up and running asap.
