Brazing with NV1 NitroVue™ Nitrogen Flow Indicator

I am a new HVACR professional who has quickly become a Uniweld fan. They have many innovative products. However, Uniweld's main distinguishing characteristic is the instructional support they provide for their products. It's consistent, well done, and communicates that Uniweld is focused on solving their customer's problems. The great part about this for Uniweld is that excellence in this area cannot be faked, only poorly imitated. Thank you!
