An impulse sealer is a device that heat-seals plastic bags closed. You place the bag across a heater zone and sandwich it down with a spring loaded handle. When pressed down, a heating element is energised for a short adjustable time and when the handle is released the bag is sealed shut by virtue of the heat fusing the two layers of plastic together.
These things used to cost hundreds of pounds, but can now be bought for about 20 pounds on ebay.
So I bought one.
Then I took it to bits.

Very informative & helpful video, in future I will search out your other videos.
Hi. Great informative video. Can I ask, can the element on a machine like this be replaced with a larger/wider one so it can make a wider seal in the plastic? Many thanks
Seeing this delay design circuit basically one also can put a 555 module laying around tuned with a good solid state relay and add a batteries or supercaps or a power supply and that's it! Thank you for saving me the money and time buying and reverse engineering this!
can you just swap out the 2mm sealing element with a wider one?
Good video
Thank you. Simple but interesting to know.
So what exactly should I swap out to increase the power to 350W- 400W? I replaced the original element with a 5mm element and it isn't getting hot enough to properly seal.
Thanks, Big Clive! You are the Best.
I = V / R
Hello where do I get the 10 mm width sealing wire?
Thank you sir
Soooo basically they are driving the crap out of the transformer ? 17 amps from that little xformer must get hot if left on too long and very dangerous.
