Ideal size airline is 1/2" to supply plasma cutter 3/8" works fine if you can keep it 6 foot long or under. From air compressor to your air filter and drier 3/4" airline is ideal but can get away with 1/2" line.
is ideal but can get away with 1/2" airline.
I doubt one fitting is the issue…can you provide a photo or description of your air system…compressor size…hose lengths…equipment in line between compressor and plasma…
one person I knew had all great fittings and proper drying systems…but had a 25’ 3/8" hose wich restricted air flow…
I had the same problem. what worked for me was to add an air dryer and replace the consumables. now it cuts beautifully.
welcome to the forum @makita …good to have you here.
good dry air is often a solution for a lot of problems
My Air system is a 60 Gal air compressor that has 3/4" line all the way to the 3 way splitter (which uses 1/4" NPT) after the splitter its 1/4" line, a filter connected to the table and then it goes to the plasma table. The length of the hose between the air compressor and table is less than 10 ft and around 4ft of it is 3/4" tubing. Other than adding more air drying systems, should I change anything about the air lines?
for one thing you ahve no way of monitoring the level of moistue in your air…in fact yoiu really have no way of removing moisture from the air…that will result in poor consumbale life and can lead to messy cuts…
where is you moisture control?..not water seperation (almost useless unless directly after tank)…but moisture control…desiccant beads and a micron filter after the beads…
1/4" line has to go 3/8 would be a lot better. Also I have had a few of those 3 ways and have had trouble with them.
I realize now that I have a very poor method of moisture control (I didn’t even know there was a difference)… I will be soon purchasing a 1qt desiccant filter and also a motorguard filter. Also when purchasing those filters I will increase the lines to 1/2"
What kind if problems have you had? Air leaking, pressure restriction or both?
What size is that Iron tee you have after the Regulator?
Do you have a auto drain on the compressor tank? or at least a manual one? and if you have a manual one are draining it every few hours while in operation? How much water do you get from it?
yup…water traps tend to work best right after compressors or after condensing systems…but…warm air holds moisture real well…so you are not giving the air a chance to cool down…I would suggest a PEX or copper wall cooler after the compressor with the water trap at the bottom…then the desiccant and Motorguard filter…
That three way looks like a Harbor Freight unit as well. And I see you reduced it down from 3/4". I see you like to live dangerously also putting a 240 volt plasma cutter under a bath tub of water.
You have the same Compressor that I have. I did what I saw online, I got a small radiator mounted to the fan cage. Plumbing was discharge of compressor in side of radiator. From radiator to disican filter , filter to tank.
Temperature of inlet side of radiator so hot you can’t touch it , discharge lines you hold onto some water from filter.
I also have a small speed air refrigeration system just to make sure.
And I live in Fla lots of humidity
I would set Piercing time longer because it has to penetrate before I can move. Good luck.
