Tandefio 40 Sticks Brazing Rods AWS BCup-1 Phosphor Copper Solder Phos Copper Brazing Alloys Flat Welding Rods Industry 0.050"x1/8"x10" for Air Conditioning Refrigerator Cold Storage HVAC Units

I do HVAC work, I used these recently to braze some fittings together on a 454b outdoor unit, they worked great will buy again

Our rooftop AC unit developed a tiny crack in the coil next to a misplaced screw when installed. My man is a skilled welder so in an attempt to potentially save thousands of dollars on buying/installing a brand new coil, we removed it ourselves and used this to repair the hole in the copper tube as well as to reinstall the coil into the unit. He tore out a section of the fin pack about an inch around the hole and cleaned it as best he could. He flowed argon through the coil (any inert gas should work) while using a propane torch to braze the hole closed (definitely want some good ventilation for that part). Back up on the roof, we did the same thing to the two copper pipe fittings to reinstall the coil into the unit. Our AC guy came out, did a pressure test, and a vacuum test/clean on the system and bam... we have AC again!!

Blazing rod work very good on the refrigeration tubing I had to make on last central A/C I installed.

I recieved it the next day after ordering it.

The solder is good for the price point but there are a lot of impurities. I have to use more flux when using this solder

Está bien y si es de confianza comprar con ellos solo que lean bien

Muchas gracias
