Review on Uniweld 40002 Nitrogen Blaster Carrying by Mark Ponnusamy

Using nitrogen to purge and protect lines during silver soldering is an absolute must. Look for videos on youtube.com showing how to work with and without nitrogen. Once you see the difference in nitrogen, you will never run out of nitrogen. I bought it to use when installing my new heat pump. Storing the parts would be easier if there was a suitably sized box attached to the bracket. Regulator, hoses and fasteners are OK. The mount and handle are well made.
