This video was shot to show the effects of brazing copper pipe (15%) while flowing nitrogen and when not flowing nitrogen....this is NOT a "how to braze" video and it doesn't claim to be one. If you are a homeowner buying a central air conditioner and your installing contractor doesn't flow nitrogen while brazing.....throw them out of your home!
