Why am I getting spotty seals on my vacuum sealer bags/rolls when using the 'PULSE' function?Updated a year ago

The way the A100 | GEN 2 operates is that it needs a combination of pressure and heat in order to create a heat seal. 

When using the regular vacuum cycle function, the lid is being sucked down into a locked position, so therefore you get a complete seal.

When using the 'PULSE' function, you will either want to hold the 'PULSE' button down on the first press or just a little bit longer (also pressing down on the lid, like you would for a regular vacuum cycle) in order for the lid to draw down into a locked position. This would be followed by shorter pulse presses until you get the desired vacuum level, and then press 'SEAL'.
