[@HVACRSurvival]

Thank you I appreciate that, I know not many people get to do these and that’s the reason why I like making the videos is because I didn’t get any help beyond what I learned on my own.

[@danielshannon167]

This commercial stuff is really cool. I did residential HVAC for a couple years so it's nice to see what else is out there and see how it's similar and also different.

[@HVACRSurvival]

The basics of refrigeration are the same but the controls are very different.

Hi Rick thanks for taking us along on this service call. I really enjoy seeing the big rack systems as we don’t get to see them very often.

[@HVACRSurvival]

Your welcome👍👍

[@robertpeters9438]

I like the commercial videos because I like the diagnosis and descriptions of the various system types. I wish these systems self isolated the bad circuit upon refrigerant loss and used vibration insulators at clamps near compressors. So much needless refrigerant loss!

[@HVACRSurvival]

I hear you 👍👍

[@christiansommer914]

You could make a system like that with common parts, but would be expensive as f***. And more that could break.

[@GrandWagJeep]

Nothing like the drone of all those recips chugging along. So much more interesting than the standard resi and package unit stuff. Dumb question (I'm not an HVAC guy)- in an installation like that where there are so many loops, wouldn't it be simpler and require less refrigerant to have 1-2 small screw chillers and run glycol loops instead?

[@Bluecollarrebel]

I miss that sound 👂of the motor room ✊🏾

[@HVACRSurvival]

It's a very distinct sound, for sure.

[@Bluecollarrebel]

It’s a sound the average person will never get to hear

[@martydzielak7924]

The discoloration on your rosebud tip is a sure sign that you are not flowing enough gas. Just like the back firing you were experiencing. A #15 tip is rated at minimum rated for flowing 10 scfh acetylene, an MC tank is rated 1.5 scfh flow. American Welding Society says tank capacity in cubic foot divided by 7 is safe flow rate. B tank is 40cf divided 7 is 5.7 cfh, still low for a #15 rosebud, but much better, often enough for intermittent use. The victor handle helps with the flow rate, probably less restriction inside, but B tanks and larger regulators are need to even approach the needed flow rate.

[@HVACRSurvival]

Number 15 is what I've got that you've seen, now I have had it in my bag and it was kind of green looking and I ran my wire brush wheel on it to make it look clean again. But I did have my regulator set at 10 and 12 I believe from what was on the instruction sheet from the manufacturer. I spent some time on the phone with the manufacturer when this first happened and did everything they mentioned but nothing worked, the length of the center connection is a little bit longer on uniweld versus Victor and I think the gas was mixing in the handle causing the problem. This is rated to go down to as little as a quarter inch up to two and seven eighths. Thanks for the info

[@SupermarketRefrigeration]

Love that tip. The #15 is my "all in one". I run it on the Victor handle with settings of 7/11. Never had any issues. Love that tip tho. Nice work. That ball valve just before the separator is awesome. Wish more people did that. I always end up having to add one after I need it.

[@BrickTop900]

I think what he’s saying is you can only draw off a certain amount of acetylene from the tank if you draw off too much with too big a tip you get liquid acetone coming out the tip

[@HVACRSurvival]

@@BrickTop900 I wondered if that was what he meant. I told uniweld what size tank I was using🤷. They said it was ok but who knows. I don't do 30 fittings at a time so that's probably how I'm getting away with it. Generally I might run my torch for a couple minutes then I'm done.

[@BrickTop900]

Nick, the over and under technique is something I learned from the audio engineer at college, and have taught it to others. Incidentally, it's the same technique that mountain climbers use for their own safety. My foreman at work asked me to do this to a 3" sandblasting hose for a food products silo. It worked well, and most importantly, the hose didn't twist.

[@HVACRSurvival]

Microphone cables is how I came about learning it. It works just make sure you unravel it the right way LOL

@@HVACRSurvival That's too big of a tip, even for a B tank. I was looking into getting a 2-MFA-J for my Victor setup, but even a size #2 rosebud is too big for an MC tank. A size 0 tip can do up to 1". A size 2 can do up to 1.5 inch. Yes rosebud is better for heating large fittings, but the Cuft per hour is too much for even a B tank. You can get rosebud tips for the Victor J series handle your setup came with, just need to be the -J series.

Sure it's going to drain the tank quickly, but I'm not doing large pipes all the time so it can be throttled down to as little as a quarter inch.

[@brnmcc01]

@@HVACRSurvival Don't starve the tip. A good way to see if you're starving the tip, is get a good neutral flame going how you like it, then cut off all the oxygen. If you get a big smoky flame, and all those little nasty strings of soot flying thru the air (we've all done it) then it's not enough fuel for the tip. A good rule of thumb is turn up the fuel just enough to clear the soot and smoke from the flame, then add oxygen. That avoids popping and flashbacks etc.
