Here is a picture of my table and one of the cuts, it is the new crossfire pro from langmuir systems. I use an 80 gallon air compressor connected to a motor guard air dryer, I tried changing the filter, and I just purchased another water trap for the side of the compressor, but I haven't tried installing it yet. I cut a piece using a speed of 10 IPM but I could tell that it was cut by the pilot arc, because the sides were very messy with lots of slag. When I cut it by hand I can travel faster than the machine, and at the same height or higher, and still make a clean cut. I have read some settings online using 45 - 50 amps at 20 - 30 ipm but when I have gone that high and slow by hand it creates a lot of slag, because of the excessive heat. I'll try the birds nest, and clean the clamp, I'm thinking it is a grounding issue, because when I have it in my vise I can cut the metal no problem, but not when it is on the table.
