I show how to braze copper line set into service valves while flowing nitrogen to avoid oxidation. i explain and show this whole process step by step. i use.

How To Braze Copper With Sil Phos Brazing Rod Youtube Purge out air – purge nitrogen at fairly high pressure in the direction of the refrigerant flow to help “chase” the air out of the circuit and fill it with nitrogen. flow with 2 5 scfh – flow with a very low flow of 2 5 standard cubic feet per hour of flow, which is just a whisper out the end. don't freak out – the very last joint can. First, you will want to remove the schrader cores from the suction and liquid line service ports. nitrogen will flow into the system through one port, and it may flow out through the other service port or out of another opening in the copper. the nitrogen just needs to flow across the joint being brazed. then, you purge all the air from the. Bert is back! he uses a setup he made for jim bergmann to demonstrate how to flow nitrogen while brazing. he also crashes the party at an install to film one. To prevent oxidation, flow dry nitrogen through the tube during brazing. nitrogen is inert, (non reactive), and will displace the oxygen to prevent scale formation. figure 3: nitrogen purged tubes at top, no nitrogen purge at bottom. nitrogen is typically introduced into the system throught the schrader valve (after removing the core), or.

Hi. i'm josh with fire & ice heating and air conditioning. and today we're going to talk about brazing with nitrogen. nitrogen based brazing or brazing with nitrogen is simply purging nitrogen through the copper while you're brazing it. that's it. it keeps it clean. refrigeration systems need to be very clean and dry before refrigerant is added. With six percent silver, this type of brazing rod starts to melt at 1,190 °c. when you’re brazing you’re going to need to heat your lines up until they’re basically glowing red. when you’re doing this you’ve got to constantly keep your torch moving, otherwise you’ll burn a hole right through the copper tube.
