Hot melt glue machines, hot melt glue guns, and hot melt hoses all have heating functions to prevent the hot melt glue from cooling during the circulation process, thereby affecting the product bonding effect. What to do if the hot melt glue tube or hot melt glue gun does not heat up? Today we will briefly introduce you to several troubleshooting methods.

1. The heating wire (rod) is damaged: first check the wiring and measure the resistance value, and then replace the heating wire after confirming the resistance.

2. Thermosensor failure: Check the wiring and measure the resistance value, and replace it after confirmation.

3. Poor line contact: Check whether the line contact is loose.

4. Corresponding temperature control meter failure: Check whether the solid-state relay has an input DC signal.

5. Solid state relay failure: Check and replace the solid state relay

6. Whether the fuse is burned out: Check and confirm. If damaged, please replace the fuse with a new one.

If the hot melt glue hose and hot melt glue gun are not heated during use, the stability of the glue will be affected. When the hot melt glue machine is used again, the solid glue in the hose or glue gun will not be able to melt and flow out, causing blockage and causing the entire set to heat up. The melting machine will not be able to be used. Therefore, when using the entire hot melt adhesive machine, it is necessary to maintain and repair it on time to avoid delaying production and causing unnecessary trouble.
