Hi,
Have had my system for a year now, and all was working 100%.
Then about 2 weeks ago, everything has changed, I can’t get a clean cut.
I was wondering if there was anyone in the GTA area willing to hangout and help, as a 2nd set of eyes would be a great help.
have you bothered to check the basics?
As @Knick mentioned, there are many topics discussed in regards to “bad quality” or “failed cuts”.
Having owned your table for a year, it would help to disclose -
Pictures, they help significantly better than an explanation. Both of the failed cuts, the table setup, and even the consumables.
A brief explanation of the issue.
Any and all troubleshooting steps you’ve done. I would assume you’ve done plenty but it would help to share what you did and what the results were.
Parameters, gauge of the material being cut, and all of your equipment.
This will help others to rule out what the possible cause might be for your issues.
It’s harder trying to find someone not just local to you, but someone that knows what they’re doing. But it’s really easy to diagnose things with the information I mentioned above.
@Caylan Welcome to the Forum.
I’m on the other end of the country or I’d be happy to come take a look.
Which plasma cutter are you using?
I’ll assume we’re trying this with fresh consumables.
Make sure the cable attached to your work clap hasn’t loosened off the plasma cutter or as some kind of other issue causing it not to complete the circuit correctly.
Maybe an issue with air delivery? Overtime your pressure drop could have increased for many various reasons?
Have you made any changes to the machine before and after the bad cuts?
Once you get past the new user. You’ll be able to post pictures on here
@toolboy are you still in the metal cutting game?
nope, i never thought about doing that.
Hi,
So, I have extremely clean and dry air (cerakote application) - I have tested and retested all connections, voltage, amps, and replaced the consumables.
It was all working perfect, then just sort of started to alternate between going too fast (partial piercing and top dross/slag) and too slow burns, sheet warping and so much dross, but then, cut perfect again.
I recalibrated the table, and started to do the whole process of test plates and seeing if I needed to change any tool settings.
I am cutting 1/8th mild steel, hot rolled
Razorweld 45cnc - 55IPM, 35A, .8mm nozzle, .070 torch height, 050” kerf width
This sounds like an air delivery problem to the plasma torch. Intermittent restriction or regulator? Unless you’re saying the tables actually moving faster and then slower without it being requested to which would be a very odd scenario indeed.
What Tin said - the table will only do as instructed (g-code).
When something is intermittent, it could be something as simple as an electrode sticking, or the diaphragm in a regulator, to electrical interference which will cause the torch to hunt, or even disconnect from the computer.
Is there any possible way we can get pictures as suggested earlier? Or even better, video of what happens? A video of the table in action, as well as a screen record (you can screen record on the computer itself and use your phone to record the table running).
ok, I will throw it out there: Is anyone willing to share their cut files? cause I am at my wits end.
Thank you all for your suggestions, and i HAVE tried them all, and others I have found on line, but still cannot get consistent clean cuts.
Sure, whatcha need?
I am using Fusion 360, would you be willing to download your tool library? and share it
I have a variation of two based on two different plasma cutters.
Instead, can you share what plasma cutter and torch you own? I can create one or someone might share theirs if they have one made for it already.
I say this because some plasma cutters go up to 45 amp, others to 60, and higher.
sorry, i should have added that… Razorweld 45 CNC plasma cutter
A published chart from Razorweld doesn’t exist that I know of, but I can start creating a tool library based on forum member’s contributions.
Do you only cut mild steel? Or do you also plan on aluminum or stainless?
The internal regulator on the razor weld is a known issue. Double check that you are running at least 70 PSI of dynamic pressure to the torch.
Also this is the cut chart directly from razor weld
It’s a good starting point but trial and error on your own machine for materials that you use most often is the best way to go about it.
I used to cut Mild Steel, Alu, SS - And TinWhisperer, I double and trippled checked my air. I have a 1000 gal tank, and 50hp screw compressor, I also watched the pressure guage and it sits at 75 psi
Which gauge?
While cutting or not?
You could have a 2000 gallon tank it’s not going to make a difference if the regulator is restricting it inside the plasma cutter. Amount of storage does not equal delivery pressure
ah, 1/8th and both while cutting and static
Which pressure gauge not gauge of material
