MICRO-CHANNEL REPAIR: Does SolderWeld Alloy Sol Really Work?

Can you actually repair an all-aluminum micro-channel coil, or is it just a waste of time? In this video, I’m putting the SolderWeld Alloy Sol aluminum repair kit to the ultimate test. Micro-channel coils are notorious for being "unfixable" because the aluminum is so thin and dissipates heat so fast. Most guys will tell you to just replace the whole coil, but that’s a massive expense for the customer. I’ll show you step-by-step how I prep the aluminum, the torch technique needed to avoid melting the fins, and whether or not the Alloy Sol flux and rod actually create a vacuum-tight seal on these stubborn leaks. In this video: Identifying the micro-channel leak point. Proper cleaning and prep for aluminum soldering. Using the SolderWeld Alloy Sol kit. Final results: Did it hold?
