@SCallahan08 I am still in the process of setting up my table, so I cannot share first hand knowledge towards that. I can, however, share that I recently became aware of air flow volume issues I had with other equipment.
In looking at all my hose quick-connects, I found that they were quite restrictive. I replaced all of them with high flow (HF) style. May be something to look at. -Steve
Well I know it may be hard to find on a short notice. Like I had mentioned before a dry air tank.
That could be a temporary fix until you get settled in.
Around here often people buy a 20 or 30 gallons compressor then decide to start sand blasting well you know what happens. You can pick up on the cheap.
If room isn’t s issue they are a nice addition. I actually have 2 30 gallons one on each end of my garage. My sandblasting cabinet pull out of one. The other my plasma and powder coating outfit pulls from with no restrictions. 8is a good way to insure plenty air.
I’ve been on the look out for a reserve tank for a bit now. I think regardless it may be a good idea to get one, even if I decide to run hard air lines in my shop.
I run 3/4" max airline through my shop, bought kit from Rural King. 100-foot kit was $89.00.
@SCallahan08 something else you could be experiencing. If at any of those restrictions there is moisture in your air it very well could be possible to be acting like an expansion valve in an ac unit. You could be experiencing a super cooling effect and actually getting microblockages of ice crystals accumulating at your next restriction area. Sometimes when I am mig welding at high gas flows I experience this with cheaper regulators. It makes actual gas flow very erratic.
Here is a thread I put together on another forum. Highlights a few choices in compressor after-cooler, air drying and plumbing. Note - I would not use PEX without a compressor after-cooler as PEX is sensitive to heat. Dry Shop Air - Step 1 (Compressor After-Cooler) | The Hobby-Machinist
I do have an aftercooler, which honestly i need to redo. Its currently off again for testing purposes but would like new lines before reinstalling.
Just wondering if you ever got the table working correctly?
Sorry I didn’t respond back until now. Basically I’ve switched to plasmadyn consumables, and running at about 200 ipm at 40 amps on 14 gauge, and bump down to 85 on detailed stuff. My table has been reliable but, I still deal with dross, but at this point I’m trying to invest into a new air compressor and lines so I’m working through it.
That is ok, I am getting my table going again. I invested in a larger compressor, and did the copper radiator, Desiccant beads, harbor Freight cooler, and motor guard m60. This seems to have helped very much.
I also am setting my cut height by voltage settings which seems to help with bevel and dross.
Have a great weekend.
Thats pretty much what I’m doing. What compressor did you go with?
It is a 5hp 80 gallon ingersoll Rand from TSC. I hear there are complaints about motor issues with it but knock on wood I have not had issues with it yet.
I went from 500 pierces on y table to 1500 when I built my drying system…I know the feeling…people underestimate dry air…
that link no longer works
That is the problem with links: they change.
You might try this. It is a link to some issues with dross: https://www.hypertherm.com/Download?fileId=HYP257271&zip=False
