– Vacuum pump

– Control circuit

– Timer

These are the parts of vacuum sealers that encounter troubles most regularly.

DZ-400 or DZ-500 industrial vacuum sealers after being used several times will be likely to have the edge of the vacuum package singed.

Vacuum sealer is a crucial part of the production line, so if you want to fulfill your enquirements of production and process products on schedule, store spare parts to replace the broken down ones or prepare some standby vacuum sealers in case yours encounter problems during producing process.

Before replacing alternative thermo-soldering cord, you need to check if the problem really is caused by the cord’s breaking or not. To do that, you can use a galvanometer to measure the electric current between the two ends of the cord one by one. If the cord does not allow electric current through, the chances are that it has been broken. However, this method does not usually provide you with an exact result. You also should remove the heatproof fabric layer covering the thermo-soldering cord for visual checking.

To know for sure if the cord has been broken or not, you need to determine its location in the vacuum sealer, then take it off the machine to check it visually for sure. In case it was broken, you can replace it with a new one basing on the following steps:

Use a pair of pincers or a wrench to remove the screws attaching the cord with the machine, then pull the cord out and put a new one into the slots of the screws.

After that, wrench the screws at the two ends of the cord to tighten it.

Remember that when you operate with the thermo-soldering cord, you should wrench the screws as tightly as you can in order to avoid their rubbing with the cord, leading to electric sparks which can make the cord break (which means to reduce the life-span of the cord).

After finishing tightening the cord and wrenching the screws at the two ends of the cord, use a heatproof fabric layer to cover the cord, which helps limit the effect of the heat towards the package and prevent the package from melting and sticking to the cord and the soldering line, making it nicer and neater.

To create the most beautiful soldering line, you need to use a heatproof fabric layer to cover the cord, separate it from the package.
