I think it might be a good idea to install the hand torch and see if it cuts, but with it showing an E04 on the display I don’t think it will actually allow a cut. I am running the plasma cutter on a dedicated 240V 60A circuit. Probably should have mentioned that too.
Try the hand torch.
The Primeweld E04 error code usually means there’s an issue with torch/air pressure or internal component fault, often related to low air pressure, moisture in the air line, or a problem with the torch consumables (like the electrode or swirl ring), requiring you to check air supply, drain your compressor, ensure correct consumables are seated, or sometimes perform a hard reset by power cycling the unit or shorting specific pins. AI question answer, so take it for what its worth. Not quite sold on it just yet.
Not Primeweld guy, but there are plenty on here.
The solenoid chattering on and off?

No. Solenoid opens to let air out and then doesn’t do anything until it closes the air at the end of the burn/should be burning cycle.
I just went back and listened to the video, you are 100% right Tin the solenoid is absolutely machine gunning. That tells me this is without question an electronics issue, although I was already in that boat based solely on the air pressure transducer not reading correct pressures.

Solenoid chatter or relay chatter is almost always caused by insufficient voltage being delivered to it.
Just got off the phone with PrimeWeld, they are aware of the issue and they have a new board that needs to be installed on the machine for the machine torch that uses the Hypertherm style consumables. Said it’s a pretty simple fix, open the machine (actually kind of a pain in the ass as I recall) and four screws to remove the original board and one plug so they are sending it out today. It’s something to do with the UPM 105 machine torch and the new board should fix it. I’m kind of wishing I stuck with the original PrimeWeld style torch but the idea of consumables that last 500% longer is just too enticing. I should have the new board by Wednesday so as always I will update when I get it installed.

Got the new board and installed it today, not sure if it fixes the torch air solenoid machine gunning or not because I still have the E04 under pressure error so I can’t cut with it.
I’m sick as a dog right now and I’m putting this aside, hopefully they have a good solution for me because I’m losing my sense of humor about the whole thing. If I wasn’t so sick this would just be an annoyance. Anyhow the re-designed Cut 60 does come apart MUCH easier than the old model and that’s a big plus since I almost certainly am going to have to take it apart again. This really sucks, brand new plasma cutter, brand new machine torch, brand new plasma table and for a week now haven’t been able to do a damn thing with any of it. The old Cut 60 was an absolute unit, so far I can’t think of anything nice to say about the new one except that it has a pre-made CNC cable which is really nice. It is definitely something in the torch though because when I hook up the hand torch everything works just fine.
I noticed in one of your other pictures of the torch it was mounted wrong, have you changed it and mounted it correctly?
Also the UPM105 will need about 10psi more then the hand torch to work properly. You should have 100 to 120psi to the back of the plasma cutter and 75psi flow pressure to the torch.

PSI is 70+ to the torch head, as for the mounting location I will take it apart and move it. I don’t know how that would affect the E04 readings but if it’s not supposed to be mounted on that part of the torch I need to move it. Gene did reach out and said he’s shipping a new upgraded unit and a UPS return label so hopefully the upgraded unit is ready to go. I think I just happened to get a machine that was missing one piece (the board for the UPM torch) and had another part that was malfunctioning (the air pressure sensor). Just dumb luck that this all happened while I was so sick, not having a functioning table the past week has had zero impact on me.

I asked Gene about this today because I didn’t find any literature and you are 100% correct, I have moved the torch clamps off the head but it has created a different problem that I’ll probably have to call Langmuir about. Sliding the torch holder up in it’s Z axis slot has tremendously limited my Z axis travel, probably removed every bit of 2 inches of vertical because the torch clamp hits the top of the housing now if I come more than 2 inches off the table. I don’t usually need much vertical clearance so it’s not really that big of an issue but I think I’d like to ask them if it’s okay if I widen the opening on the top of the housing to allow the torch clamp to slide through the top of the housing.
All that being said, I received the new unit from Gene yesterday and had time to install it after work. Works like a dream now! No more E04, no more machine gunning solenoid just proper operation. I did notice I’m going to have to build a new feeds/speeds database though as it seems the Hypertherm style consumables aren’t going to require as much power for the same thickness cuts. Here is a video of the table making it’s first cut after hooking up the new Cut60. As always PrimeWeld continues to be the gold standard for customer service. If anyone is on the fence about going with PrimeWeld do yourself a favor get off that fence immediately. Now I just need to build the air drying/cooling system on the wall, move the table into it’s final position and top off the table with plasma green.

Be careful cutting with the water table that low on fluid. Might cut through

Absolutely, only test cuts until I get the table setup permanently. I made sure to keep it off the seams and a fairly low power cut with 14 gauge. Anyone here know if the longitudinal braces across the bottom can support the table if I get a pallet jack under there to move it? I figure with the amount of water in there right now the table is probably sitting at maybe just over 1100 pounds. I’ve got a pallet jack that would make moving the table super easy but last thing I want too do is collapse a brand new table.
Remove torch holder from z axis plate and flip upside down, will regain the z axis travel clearance.

I thought about doing this at first but when I revisited the assembly instructions it did show a specific orientation. Can’t think of a reason why that orientation couldn’t be inverted though.
I bought a pair of car dollies to help move the table, going to put one side on the dollies and I’ll lift the other side with the pallet jack. That should be enough load dispersion to move the table safely I think. Also started on the cooling/water separating system today since that has to get finished and bolted to the wall before I move the table back into position. I’m using 50’ of 3/4” Schedule L copper with 5 water knockouts straight from the compressor pump and then to the compressor tank.
That is 10 runs at 5’ each, the side facing up is the side that’s mounting to the wall. Not sure the Shark Bite ball valves can handle the pressure, hope so.

All done. I want to see it cycling for a week before I’m going to be comfortable with it but even the shark bites held. Need to run a few cycles today and check the temps at the compressor outlet and tank inlet to verify whether or not this was worthwhile but I’m optimistic. Today I put the car dollies on one side and move the table into it’s final position, then top off the water table. Shop is almost ready for business, have to build the new powder coat oven and then I need to make a decision on whether or not to pull the trigger on a lathe.

Do you have flex lines at connections from compressor to copper lines at compressor? them lines will crack at fittings if no flex due to vibration.

I am guessing the way you have it hooked up is just to test it, right?
