hello friend waiting are well I have a bag sealer that has a control more than anything with a rheostat, the problem is that it does not take anything and disconnects and I climbed everything to the rheostat and if it takes a little longer but for what I want it it is not enough to heat the resistance because it goes off I would like to see if I can increase the time for it to take longer and reach a little more heat. that I have to do ? just changing the rheostat will solve the problem? or something else to change I attached the images and there you see the number of resotato thank you https://adjuntos.yoreparo.com/imagen_post/0004/85/05a6694a43331a81c3ae511fcf1f8a07f94afe28.jpeg" alt="" />
