What to do if VALCO MELTON Melting Machines have no adhesive output?
- D
  Dr. Shannon GloverAug 4, 2025
  If your VALCO MELTON Melting Machines are not dispensing adhesive, there are several potential causes. First, ensure the adhesive is hot enough by checking the temperature setting, reservoir heater power, and fuses. Verify the pump is functioning and the system is ready, also check for blown fuses. Other possible issues include a cold or damaged hose (replace the hose), a cold applicator (check for blown fuse or defective heater), a clogged applicator (service the applicator system), or a clogged filter (replace the filter). Finally, a temperature control malfunction could also be the reason (replace temperature control).

How to fix VALCO MELTON Melting Machines when material in reservoir will not melt?
- J
  Jon WilliamsAug 10, 2025
  If the material in the reservoir of your VALCO MELTON Melting Machines is not melting, it could be due to a few reasons. Check the indicator lights and reset the temperature adjustments in case of a temperature control malfunction. Inspect for loose, broken, or shorted connectors on the heater or wiring harness; tighten any loose connectors and repair any broken or shorted ones. Also, check the circuit breaker and fuses, replacing them if necessary.

Why is adhesive charring or gelling in the reservoir of VALCO MELTON Melting Machines?
- D
  Dylan HollandAug 16, 2025
  Charring or gelling of adhesive in the reservoir of VALCO MELTON Melting Machines can occur due to several reasons. The reservoir temperature might be too high; lower it according to the adhesive manufacturer’s specifications. Surface oxidation of the adhesive can also be a factor, so keep the reservoir closed. The adhesive might have poor heat stability, in that case change the adhesive or hold the reservoir temperature at a minimum. A low reservoir level can also contribute, so keep the reservoir full. Finally, a temperature control malfunction could be the cause, so replace the temperature control.

How to troubleshoot uneven adhesive flow in VALCO MELTON Melting Machines applicators?
- A
  Alicia WrightAug 22, 2025
  Uneven adhesive flow to the applicators in VALCO MELTON Melting Machines can be caused by several factors. If the reservoir temperature is too low, raise it according to the adhesive manufacturer’s specifications. If the adhesive is overheated, reduce the reservoir temperature accordingly. Ensure glue hoses are at the same temperature by resetting the temperature controllers and use hoses of the same length. Replace any crimped or leaking hoses. If the adhesive supply is low and the tank sides are charred, drain, clean, flush, and refill the system. For a manifold or nozzles that are partially clogged, drain, clean, flush, and refill the system, inspecting for charred adhesive and foreign matter.

What causes fuming or smoking of adhesive in the reservoir of VALCO MELTON Melting Machines?
- A
  Amber MarshallAug 28, 2025
  Fuming or smoking of adhesive in the reservoir of VALCO MELTON Melting Machines is caused by the operating temperature exceeding the adhesive's recommended temperature. Keep the setpoint within the recommended range and keep the reservoir covered. You might also consider using another adhesive.
