Hi,
Just like the title says does anyone have some sort of refrence material for settings such as amps, psi, pierce delay, travel speed, etc? It would be really nice to have this for mild steel, stainless, and aluminum.
Thank you,
Those will be determined by which plasma cutter you have.

There seems to be no reference material for mine it is a cheap Plasmargon PLC 55 pro. I figure it would be better than nothing to use the settings someone else uses for a machine with similar amperage.
I see you are having other troubles too. Have you confirmed it isn’t a high frequency machine? If so scrap it you will damage your control box.
LS has a compatibility list

It looks like it is pilot arc machine. I sure hope you don’t plan on using the internal compressor for use on the table. You will need a dedicated compressor that puts out at least 5 cfm.
Here is a ball park chart to start your journey.

It’s hard to find any specs on that machine, but every picture I’ve seen shows a high frequency torch.
“Pilot arc” is a term used for any torch that doesn’t use scratch start. It doesn’t necessarily mean it’s a blow back start. Lots of cheap high frequency machines use that term.

If what David says is true, you might be chasing your tail with your other issue:

It says cnc compatible right on the machine:

Maybe not, but I have watched videos of people using these with cnc tables. I have also read a forum here where a user was told it looked like it used high frequency, but he ended up getting it working. I have also cut out many, 30 maybe, fairly clean rectangles with numbers in them. If it doesn’t work I will buy a new plasma cutter.

Just because it is CNC compatible does mean anything here. Langmuir isn’t compatible with a high frequency plasma. Confirm it isn’t because if it is you are going do damage the electronics on the table

How do I confirm that?
One langmuir has a plasma cutter compatibility list on the main site .
Two if it is a high frequency it isn’t compatible. Using it will damage the electronics on your table.
I know that’s not what you want to hear. There are great machines that are not too expensive that will work. The harbor freight plasma several people have and do use it .
Just drilling you so you don’t fry something. Like I said not knowing the exact model what I seen said it was high frequency.
Maybe @mechanic416 can chime in
Here is that compatibility list. Keep in mind, other cutters might work. These are just the ones that Langmuir has tested or have reasonable reliability of reports that these cutters should work without too much of an issue.

I believe if the electrode has a spring mechanism that is activated by air, you can be reasonably sure that is a “blow-back” start and thus would NOT be a high-frequency start machine.

If you take the nozzle cap off the torch and press on the electrode inside. If it moves up and springs back is a blow back style. The discription on Google says it’s HF.
Our upgrade new plasma cutter PLC55X is IGBT technogy, not MOSFET. IGBT machine is far superior and more stable than the MOSFET machine.
IGBT technology can effectively save 50% of energy.
High frequency, DC output, Advanced inverter plasma cutter technology.
Strong interference resistance, continuous current regulation, stable cutting current. Waterproof, shield from electric shock.
Max cutting thickness is 1/2”, Suitable for cutting Stainless steel, copper, iron and aluminum metal etc.
No noise, high cutting speed, cutting smoothly and no polish demands.
Equipped with a portable handle, it’s very convenient to carry.

That plasma cutter is a HF unit with a pilot arc P80 torch. It will not work with the Langmuir electronics.

I believe you. It does use a P80 torch and that torch is definitely for a HF machine. Well I figure the Primeweld on the compatibility list is probably the cheapest option. Does anyone have any recommendations for something cheaper?
Does this one seem like a bad idea:

I marked the parts I liked about that Lotus:
You would know if it was performing better than what you have.
But it really usually is “you get what you pay for.” Maybe it works for a few days or weeks or years. You know what your finances are. We don’t. We would all like you to buy at least up to the Everlast range because we want you to not be fussing about with perhaps a less reliable cutter. I have no experience with Lotus. I did buy a YesWelder welding unit and it was cheap as dirt but I love it!
Free returns! Can you get better than that?

I’ve been using that one since 2019 without a problem, but it is a low cost PC. 1/4" steel? Sure. No problem. 1/4" AL? um… I wouldn’t try it unless I had to.
16-11ga material? Yup, it works fine as long as you’re not too fussy about edge quality.
And no interference with the Control Electronics, but I have the original CrossFire Mach 3 system so YMMV.
If I bought a new PC, I’d probably follow @Bigdaddy2166 's recommendation.

For $400 more you could be “driving” this sweet model and be covered by their customer support. I have heard good things about Everlast customer support.
Metal costs are not coming down anytime soon…maybe never. When the plasma cutter messes up, you could easily lose $200 worth of metal in one afternoon.
Edit: But I think BigDaddy was recommending the 62i or the 82i. BigDaddy (or others)…can you weigh in on this?

I am thinking about getting this 52i. Do you think it is significantly better than the Primeweld? I assume with a $140 difference it is a no brainer?
The fact that George said this, I think you would be okay either way:
If you were expecting this to be a full-time business, I would probably go with the 52i. But think of it this way… You go with the Cut 60 now. Once you have a booming business you might just go 82i or Hypertherm at that time.
