The motor guard will catch any potential final contamination. Dust from the dessicant beads is something you don’t want in your machine.
Show us the bad cuts? The tips are out of round, but not blown out like we see usually.
It wouldn’t finish the cut sort of like it had tabs in it so I had to take a screwdriver and pop them out
Pardon me for interrupting, I have been following this conversation as I too have recently purchased a 45 sync cutter.
A couple of things I noticed; you say you have 80 PSI to the cutter; that could be a bit low. The maximum inlet pressure for the 45 sync is 125 PSI, so I would be inclined to up it to 100 - 110 PSI just to make sure the cutter has all the air it needs.
The picture you show has 18 pierces in it and if you have cut 90 of them, that is over 1600 pierces, that is pretty darn good.
I recently had a problem with some 10ga steel that had some really heavy hard mill scale on it. A 40 grit flap disc wouldn’t even cut through it. It was so thick the electrical contact with the arc was lost and the arc extinguished. From the look of the pictures, the scale on the plate you are cutting looks very familiar.
Just a few thoughts, again, sorry for interrupting.

@curmudgeon That’s excellent input. Well put! I didn’t even catch the pressure to the cutter, great point. I have been a bit out of the game so I may not be up to what I used to be able to catch.
I have heard people talk about mill scale issues, but I’ve never had any issues cutting through it, sanding it, ect. There are different grades of hot rolled however, so it may depend. I use two different grades depending on who I buy from.
I realize my initial reaction of thinking it wasn’t good lifespan is probably off.

I second what @curmudgeon is saying.
As for the scale/rust on the metal, you want to clean of a section where your work lead clamp attaches. This should be shiny metal.
You might want to check/clean the work clamp as well.
no thank you all the help is welcome
i used 2 tips for 90
i am at 80 because that what langmuir said one day
This is what your manual says:
You machine is safe to have 125 psi to the back of the machine. Most of us with Hypertherm have around 100 psi to the backs of our machines because the machine self regulates. Notice the limitation of max 135 psi (because they feel the bowl of the inlet filter might be damaged).
And unless you have a pressure gauge on the back of your plasma cutter, you might not know exactly what that drops to while the cutting is occurring. If the torch is starved for air you will burn up consumables and may have difficulty keeping the torch burning or trouble starting the plasma cutting.

i will jack the air up thank you
thank you all for your help . i bet this was the problem. may i ask does anyone make parts for a living

Glad you got it straightened out. This device, although it looks simple, relies heavily on many functions working together. I would have thought 85 psi was sufficient. No, I don’t make parts for a living, but I do utilize this for company projects.
Oh, and I do make muskrat guards and raise them on the side.

This is my first job before I’ve been doing onesie two things this one it’s 176 parts that’s prime and painting and high gloss in them and I did $14.25 per part. With steel at $120 a sheet 3 sheets. And to be honest, I only figured one consumable tip.. does anybody know what they would charge?
Good advice from one of your past threads. Did you try it?
Bypass all those filters and regulators and desiccant cells
inlet pressure 85 mininum !

Yes I did
I went from 1/4 hose and regulator to what I have now .
I was at 110 psi and when I called Langmuir they said bring it to 70-80 psi so I did
Now I have a new air compressor to 1/2 tubs industrial dryer 1/2 tube to 3/4 silicone beed regulator 3/4 pipes through my shop to 3/8 hose to a 3/8 silicone need dryer regulator to a 3/8 hour to the cutter
Oh reading above it sounded like you were still using all of those filters you have pictured and I thought I read you were set at 80 psi not 85 psi as was suggested. Have you tried testing what your pressure drop is across all those filters? I would be curious. The symptoms sure seem like you are staved for air but if you have tried bypassing all those filters and upped the pressure as you said that didn’t help then perhaps a blockage somewhere. Perhaps dust from the desiccant filters is making it to the cutter causing issues.

At the cutter I was maintaining 80 tonight . I have not reset the regulator yet because when it was suggested, I was closing up for the night. My compressor switch’s back on at 120psi (175 max) . The main lines in the shop maintain a min of 110psi when the compressor is refilling.
I had the cutter set to 80 psi after tin whisperer did his recommendation in after I changed up my whole shop air system . Because I had another problem and that what Langmuir said to set the air to
