PAC Machinery Group W400 Series Impulse Sealers Model W400-12

Impulse type sealing arms are electromagnetically activated with foot pedal switch. Heat is applied by both upper and lower sealing bars for a positive liquid and airtight seal. No preheating is required. Both sealing bars are cool when not in use. The seal width is approximately one-eighth inch. An audible time-temperature cycle indicator is included on all standard units. The audible indicator is not provided on units with optional dwell control. The time-temperature cycle is precisely controlled by a solid state electronic timer. It is infinitely adjustable from a fraction of a second to five seconds for sealing a wide variety of films and film thicknesses. On heavy films, the operator can allow more time for a seal to set, after completion of the sealing cycle, by keeping the foot pedal depressed. Teflon® covering prevents firm from adhering to sealing bars during cycle.
