I agree. It’s just disheartening to see the pressure gauge reading off by ~10% when they won’t let you run it over a certain setting. I have three gauges that all agree, and the Everlast is 6psi higher. Oh well. If it cuts without freezing my table I guess I can live with it. 
a lot of people run a dry air tank after all their air drying equipment to help with pressure drops.

And I guess I can see why they do. I’m not nearly as smart as most of the people here, but I’m pretty sure that if the compressor turns off while you’re using the tool, then you have enough air.
well, anything you do to dry air also restricts it which can cause the pressure to drop. i just because i had them stripped 2 small 30-gallon compressors down put them in line after my air dryer for a bumper to help prevent it. i only have a small filter after them to catch anything that may be in those tanks.

I’m not saying it isn’t a good idea. I’m just past the stage where I’m going to stop and re-do everything AGAIN. It just seems like if you talk to 10 people, 2 of them will tell you “you’re doing it all wrong”, no matter what you’re doing. And I guess it’s been a while since I’ve been SOOOO new at something, that there’s a part of me that’s still trying to listen to everybody’s advice.
i got you i wasn’t making the recommendation. more the less explaining how people get by with it. i don’t blame you for not wanting to replumb your setup.
when i started modifying my air setup i could notice a definite pressure drop because of all that i had done. where i live without all my air setup my compressor gets mistaken for a pressure washer.

MY setup drops 5 to 7 psi when I check flow with switch on my PW60. I’m running 120 psi into back of cutter. Water separator, desiccant dryer and a motor guard all running 1/2 id lines and fittings to back of cutter. Short lines though.

We’re on the same page. I’m just complaining.

Thank you. I seem to think that’s probably fairly normal with good filtration. I know some of these guys have fancy industrial compressors that cost tens of thousands of dollars, but this was supposed to be an entry-level machine.
I have much more pressure drop than you and mine works fine. I have mine set at about 81psi static and it drops to 65 when flowing. I do need to investigate and see if I can minimize some of the restrictions, but the dessicant and motorguard have to stay.

Thanks Dave. Helps to know I’m not losing my mind.
but wait Casey!!! you got the name CrazyCasey for a reason now…
some time we got to vent i know. just don’t want you to think i am telling you to spend money.
the way mine is set up i have had drop lines for years in my garage. i plumbed the in at my drops. my plasma and powder coating gun pulls straight of of one tank so i have at least 30 gallons of unrestricted flow

Input pressure affects output pressure. 3 to 7 psi is acceptable over that you have a restriction some were. Most likely the motorguard filter. They need to be changes about every week unless you have test gauges on the input and output to check them for a restriction. You never reuse a filter as it will never reseal once compressed.

George, I’m curious if this recommendation is based on constant use or would it also apply to hobby use of maybe an hour a month? Probably a moot point for me as I do plan on putting a gauge in between the motor guard and the cutter since the Titanium 45 doesn’t have a built in air gauge.

I can’t remember where you live/humidity risk. Are you going to add or do you already have a refrigerated dryer? That’s my next step if what I have isn’t enough.

If the filter gets wet/damp then sets it can/will cause mold, mildew and the housing to corrode causing the power coating to come off getting into the air system as well as a leak or not being able ti seal. Seen this a lot so I don’t use them.
Its like those little filters they have on and in plasma cutters. If they are brass they can be cleaned. If they are other stuff they should be changed every 30 days. And I can bet you will have a hard time finding them and all they really do is take out some rust flakes and dirt NOT water.

I changed my motorguard filter and saw no change to my pressure drop. I tested removing various components from my system, one at a time, and it still didn’t change my pressure drop. I even went directly from my 3/4" copper pipe system to the filter/regulator that came with the plasma cutter and I still get a significant pressure drop of around 20 psi. I’m fairly certain that the culprit is the filter/regulator that came with the plasma cutter.

Remove it as its not really needed as you already have filters in line.

I removed it, since I have another regulator within reach of the plasma cutter. There is less drop now, but it’s still around 13psi. The other regulator only shows a 2psi drop, so the restriction must be inside the machine.

I have a test gauge I plug in the hose going to the plasma cutter set it at say 75 psi then plug the hose to the plasma cutter and see what the gauge reads on the plasma cutter to make sure they are close to the same. Now I have seen on the Everlast plasma cutters that will vary to about 10 psi in some cases due to the air sensor in it.
