Identifying Malfunctions in a Glue Gun

In diagnosing a fault in a glue gun, it is important to evaluate specific problems and their relevant metrics. Therefore, malfunctions metrics are divided into four categories with specific characteristics.

• Details: The heating of the equipment is not up to the mark. The irregular heating may be resulting from the defect of the thermostat or the heating element.
• Indicators: The bond can break with little external vibration and application of the adhesive is uneven.
• Solution: Thermostat and heating element replacement must be done per the specifications of the manufacturer.
• Details: Over time the adhesive tends to accumulate in the nozzle. This will block the escape for the glue resulting in adhesive flow restriction.
• Indicators: Seldom or no delivery of glue, and poor glue application. Adherence gets interrupted often during processes.
• Solution: The nozzle must be overhauled using manufacturer-endorsed cleaning utensils. Restriction of movement due to excessive heat glue in the guage should be kept to a minimum.
• Details: Fault in glue gun operation may be caused by faulty internal wiring, disconnection in glue gun, or defective power supply.
• Indicators: The heater is not engaged in its operation, it goes off suddenly and sparks are seen.
• Solution: These are symptoms of profit or loss. The secondary side works at reduced voltage. Until proved otherwise, these suspicions appear to have some validity. Repair the internal wiring and externals concerning the glue gun using safety guidelines.
• Details: Progressive wear or misalignment of mechanical components within the trigger may impede the feed of glue sticks.
• Indicators: Problems dispensing glue adhesive or a non-uniform flow of glue adhesive with the trigger.
• Solution: Replace parts that have alignment discrepancies. Restore alignment according to the recommendations given by the manufacturer.
