  Erin VasquezAug 5, 2025
  If you're experiencing no adhesive output from your VALCO MELTON Melting Machine, several factors could be at play. First, ensure the adhesive is adequately heated by verifying the temperature setting, checking the reservoir heater's power supply, and inspecting the fuses. If the pump isn't running, confirm the system is ready and check for blown fuses. Cold glue hoses or applicators can also be culprits, suggesting a hose replacement or checking the applicator's fuse and heater. Additionally, a clogged applicator or filter can impede output, necessitating service to the applicator system or replacement of the filter. Finally, a malfunctioning temperature control might be the issue, indicating it needs replacement.

Why is adhesive charring in my VALCO MELTON D4-E Melting Machines?
- C
  Chelsea PierceAug 11, 2025
  If you notice charring or gelling of adhesive in the reservoir of your VALCO MELTON Melting Machine, it could be due to several reasons. The reservoir temperature might be too high; if so, lower it according to the adhesive manufacturer’s specifications. Another cause might be surface oxidation of the adhesive; keeping the reservoir closed can help. Poor adhesive heat stability may also be a factor, suggesting a change of adhesive or maintaining the reservoir temperature at a minimum. A low reservoir level can contribute to this issue, so ensure you keep the reservoir full. Lastly, a temperature control malfunction could be the cause, indicating it needs replacement.

Why is adhesive smoking in VALCO MELTON Melting Machines?
- B
  Brad TurnerAug 17, 2025
  If you observe fuming or smoking of adhesive in the reservoir of your VALCO MELTON Melting Machine, it's likely that the operating temperature is exceeding the adhesive's recommended temperature. To resolve this, keep the setpoint within the recommended range and ensure the reservoir is covered. If the issue persists, consider using a different adhesive.

  Sherry GarciaAug 29, 2025
  If the material in the reservoir of your VALCO MELTON Melting Machine isn't melting, several issues could be the cause. It could be due to a temperature control malfunction or incorrect adjustment; check the indicator lights and reset the adjustments. Loose, broken, or shorted connectors in the heater or wiring harness could also be responsible; tighten any loose connectors and repair any broken or shorted ones. Lastly, a tripped circuit breaker could be the cause; check the fuses and replace them if necessary.
