Just like any other machine, impulse sealers require maintenance every now and again. Although these machines seem to require less maintenance than most, the most common thing that will need to be done is to replace the heating element so you can continue to get nice crisp seals on your poly bags.
When should you replace the heating element? Typically you'll have a feel for the way your bags should be sealing and you'll just know something isn't working as well as it should. The bags may be burning through instead of getting a good seal. Or you might not be getting a seal at all. These are both pretty good signs its time to replace the heat element.
You have two options. You can send in to the place you bought it from and have them replace it for you. This is going to cost around $20 in total shipping to get it there and back, plus $25 or more in labor along with the $20 to $40 dollars in parts depending on how big your sealer is.
The other option is to replace it yourself and lucky for you this is a really simple process. The first thing you need is a heating element kit. It will consist of teflon tape, and a heating wire with eyelets attached at both ends. Once you have that, follow these simple steps:
1. There are two metal plates holding the old teflon tape in place. Each plate will have two screws in it. Completely unscrew and remove one of the plates. Loosen the other plate enough to remove the old teflon tape.
2. Now that the tape is removed, you will need to remove the screw that is holding the far end of the heating element in place. After removing the screw, simply lift the wire off its tensioning device.
3. Place the new wire over the tensioning device first and then screw down the other end tight, but don't over do it.
4. Take the new teflon tape, slide one end under the plate that you loosened, fold the tape over the sealer, press down a bit so it will stick, and screw back on the plate you removed to hold down the other end of the teflon tape.
5. Now turn on your impulse sealer, seal it down once to test it out.
Your bag sealer should be as good as new.
