I'll start off by saying this is the first time I have used a plasma. I bought this for my jeep addiction as I found myself doing more projects that caused me to hate my 4" angle grinder as a cutter.

Right out of the box I tried cutting some 3/16" plate and made a mess for about 5 minutes, then I sort of got the hang of it and cut the plate like butter with nice clean cuts. I went on to cut out some brackets from the 3/16" plate that involved some curved cuts and I was getting better. After this I cut off some stock axle brackets which were 1/8" thick at the welds while under the jeep in awkward positions.........these cuts came out much better than I expected and went extremely quick. I cut out some sway bar extensions from 1" wide 1/4" thick strip and while it made quick work of cutting the cut was not as clean as the 3/16".........still I was happy with its performance. I then tried some 1/4" plate that I needed some gussets from and lets just say I had some trouble. I maxed out the amps made sure the psi was at 70 and went slow to finally get them cut out, although they did require a bit of grinding. Maybe I shoud have changed the consumables before cutting the 1/4" plate because I had a lot of cutting on the original set.

All the plate I cut was cleaned with a flap disc before cutting and the 40d was wired up at 220. So, was my experience typical at 1/4" or is my in-experience with plasma what is making the 1/4" cut.......well, not good?

Hello,

The machine should be cutting at 1/2 inch perfectly and cleanly. Check the consumables and check the air pressure making sure you get constant pressure at 70psi at the regulator.

If there is anything else, please let us know.
