Having an issue with bottom dross all of a sudden. It’s like a perfect bead of dross all the way around. I always cut 16 gauge and I haven’t changed any settings so I don’t know what could be causing this. The only thing I can possibly think of is I recently realized I left a couple pieces off of my Cobalt compressor, which is already underpowered (the black Cylindrical things pictured). I take it these are here to cut back on the noise because it got way quieter once I put them on but I’m wondering if it also didn’t slow down how fast my compressor can build up pressure. Any ideas?
Additional info: tried replacing the consumables, that wasn’t it. Also removed the inlet filters that also didn’t fix the problem.
Is it possible it’s just wet air? I have a cheap water separator between my air hose and my cutter. I’ve never had a huge problem with wet air so I don’t know how to identify it. I’ll include a picture of my filter.
I took them off and I’m still seeing the same issue. Is it possible it’s just wet air? I’ve never had a huge problem with it so I don’t even know how to identify if that’s the problem. Would completely emptying out the compressor and starting a cut be a good test?
Quality consumables? Or Amazon/Plasmadyn junk? It sure looks like a foul tip and electrode to me. Also what is the air pressure at the plasma cutter. 70 psi min.
Yeah they’re cheap Amazon consumables I mean they’re from the same batch I’ve been using without a problem. It could be the consumables, I can’t rule that out. Any recommendations for good ones for the primeweld cut 60?
@mechanic416 sells only top-shelf stuff. Just send him a message. I started using shielded consumables lately and will never return to the unshielded version. I buy all my consumables from George.
If all you have for water/moisture control is what is pictured and the little filer in the plasma cutter it could be a moisture problem. Also the compressor air inlets are to close to the wall. The closer the compressor is to the filter setup and the plasma cutter the more moisture you will get as the air does not have time to cool down.
It’s a little water filter in the picture is about 20 ft away from the compressor, next to the plasma cutter. I changed the consumables again and I completely emptied out my compressor tank. I just noticed there must be a slight leak at the connection to am air filter (pictured) and, even though you can see it there, there were moisture bubbles appearing at that connection which I can’t expect is a good thing.
My setup is compressor —>25’ hose ----> cheap little air filter on my table close to my plasma cutter ----> hose that should be like 2’ but it’s actually like 15’ because that’s what I had → plasma cutter. This seems to get worse now matter what I try (see pic)
Bottom side dross increases when the torch height is too low or the cut speed is too slow. That looks more like the cut height issue. Have you checked your cut height?
What is the CAM’d cut height and what does the height measure when you run this simple gcode file: cut height test.tap (224 Bytes)
But, if you have a high moisture content in the air, that is likely the issue.
Not saying that it’s not the torch height but it’s certainly weird that it would be an issue all of a sudden. I will look into it.
Seems like no matter what I do, when I empty my compressor the air feels moist. That’s not unusual for me, In the past I think my air filter dealt with it but I’m wondering if I need a new one. Any recommendations for a different one?
) have had the cut height change with just the use of a different computer with the same setup.
