I am looking for guidance from any of you that have had success using fine cut consumables. These are my results trying to use them (again) and I’m having no luck. The results make no sense to me. Cutting the outside part of the circle did not cut all the way through and had massive dross on top, yet it cut several cherry blossoms fine. 14g, 160 (tried up to 200) ipm 45a nominal voltage set to 78 HYP 45XP, IR single stage compressor, refrigerated drier and motor guard filter. Any guidance would be appreciated.
Each time I try the fine cut consumables, these are the results I get. Normal consumables work fine. Using genuine Hypertherm consumables.
That looks like either the work lead is not connected on the steel, or to the plasma cutter,
OR
The gouging button got pressed. Left side of the control panel on the cutter, two LED indicators one above the other. The top one should be lit. If not then push the soft button next to them.
At the beginningg of the cut, the consumables were fresh out of the package. I’m using Fuion, will post the lines when i get to a computer, photos will have to wait until I get home this evening, I can tell you the part numbers match what is shown in the cut chart.
Both are connected, ground is attaced to the sheet metal directly. Just prior to this failed attempt with the fine cut consumables, I cut a piece of 3/16 steel and it was fine (using normal consumables). Gouging button isn’t pressed, the cutter is in cutting mode.
One thing I failed to mention was about half way through the cut, the program just stopped, amber lights on the torch status of the table and for quite a bit of time (around 30 secs) there was no error or fault displayed in Firecontrol. I hit pause and then resume and finaaly got the THC alarm stating the torch list fire. No strange display lights on the torch. Generated a code to restart the program at the line of code indicated and it finished the program with these lackluster results.
Even the flowers look nasty. Check your cut height. THC on or off?
If the THC has voltage sense issues, it will continue to raise the torch until flame out or it might just get the reading it wants, and it won’t care that the cut height is now .5" instead of .06"
Agreed, all of the cuts are terrible. My earlier statement was that it seems to have cut the flowers better (not perfect) than the outer ring of the pattern.
THC on. I ran the cut height program a few weeks back and it was fine. I don’t believe this is the issue because normal consumables don’t give me this result. I will certainly confirm when I get back home.
If you did this, any adjustments to had made to cut speed and pierce delay in firecontrol would have defaulted back to the post processor settings. So if you cut quality changed drastically after doing that, there is where you should look.
@Sticks will attempt with THC off when I get home this eve (time permitting). If it is THC, it is strange that it only rears it’s ugly head when I am attempting to use fine cut consumables.
@brownfox I am running a Hyp 45XP. I will post pictures of the packaging of the consumables when I get back home. I was getting crappy cuts before the program stopped. I was adjusting feed rate during the cut before and after the program alarmed out.
I didn’t inspect the consumables after this horrific attempt last night, I will remove and inspect those as well.
