I use a regutator to reduce the extream pressure, I attached a clear flex tube, then I put a piece of new break line in the end hose. After sealing all but the last 2 inch or so of the bag I push the wand "line" to the botom of the bag. I let the bag kind of baloon up some by holding the last bit shut by hand , then let go and push out the air - nitrogen mix. I continue the nitrogen flow and baloon it out again.
shut off nitrogen, pull out wand, squeze out the excess nitrogen and quickly seal the last 2 inches. be carefull as you can not to let any ari back in after the final squeze till you get the seal done. very easy with a helper.

I use an aluminum strip from the front of a tool box, as a seal bar because it has a bunch of ribs in it the entire length, this results in MANY seals. I screwed the strip to a piece of 1" X 1/8" steel to support it but a piece of wood would work just fine too.
I heat it with an iron to seal. I hold the iron still for about 8 seconds at allmost the hotest setting. I lift the iron and them press-rub with a paper towel immediatly. this will assure a GOOD seal!! then move the iron forward along seal and repeat steps till it is sealed, remember to leave the space or the nitrogen if you are useing it..
also allways use oxygen absorbers. just to be 100% safe.
