Planning to order OEM consumables on my next paycheck, bought generic because they got here in a day or two instead of a week or two.
swapped them out, and when I do a THC test the following happens
Fine cut:
at 40 the Torch fires for a split second then goes out.
if I bump the amps back to 45, it sputtered 4 or 5 times and stops
OEM working standard cut:
45 amps torch fires till I hit the “it’s firing” button as expected
40 amps, it does the same sputtering thing
2 questions,
Is this a consumables problem or a me problem? what else should I try to get the full duration plasma ignition out of the fine cut consumables? Is there a particular piece I should suspect is the cul\prit? I did try a whole new set of consumables, and got the same result
The sputtering seems to be the plasmcutter detecting a tip/ amperage miss match… how exactly does it do that , I don’t see any circuitry in the consumables. they all ok solid metal or ceramic.
I had that sputtering affect when I installed the consumables wrong. I can’t remember what I did but check the orientation and re-load the consumables.
The fine-cut consumables require a different swirl ring; the standard one will not work with fine consumables. It has a completely different part number.
Can you attach your gcode files to a message so we can see the settings? (mark them so we know which is fine-cut)
Can you post a photo of the consumables? with good focus the end and inside of the nozzle.
I was just doing the thc test where it lights the torch till yo kick the button… , after I figured out there was an issue, and that reproduced the failures with fine cut above.
It doesn’t outright say do not use them for aluminum but it’s implied by its omission in the description of its use. Where aluminum is clearly listed in the 45 amp standard consumable category.
