PMX 85 cutting quality

[SegoMan DeSigns]

personally never, it's a machine that I've had for a year and I do very little cutting with it. I'm a farmer, so not a metal craftsman!!!!.

Farmer or not your machine still requires proper setup, maintenance and inspection just like the other machines do.. Did you buff an area clean for your work lead to attach to? What type of torch are you using, hand or machine? Is this a SYNC system? Lot's of unknowns here.. You need to address everything the forum members posted here to achieve optimal cutting.Here is what my Hypertherm machines can do


This is 1/2" plate cut at 65A, for reference the penny is 3/4" OD

This is 3/4" cut at 85A

This is 1" cut at 105A:

This is 1-1/4" cut at 105A:

indeed, i have to admit that the work is remarkable, bravo. i will try to check again all my parameters and status of everything that is mentioned throughout this discussion. so yes, i stripped for the clamp, it is a machine torch and a basic pmx85.

Steve - those are some super nice looking cuts. I agree with the suggestion that perhaps the op might check his 0-rings for wear or leaks.

Thanks David,

Before I got into the business of sparks the only CNC plas table available was an older (well used) Koiki machine that was100 miles away. It had less than stellar cuts, the only other option was a water jet at 3x the cost. I had a never been used TM Growth Series 2'x2' gantry appear on my door step, the previous multiple owners was unable to make it operate, I had it working in 2 hrs and started the build for the base on the Shiny Keg Plasma Kutter. The 1/2" job above was one of it's first cuts. It was definitely a Tarzan Yell & "Beat on Your Chest" moment for me. I used it to make parts for the 6x12 build which did the rest of the cuts shown above:

These machine are a bit finicky at times which requires 3 dimensional critical thinking skills that Mr Spock talked about on Star Trek.

if you have some time, could you try to cut out the shape that I cut out to see the result that you get to realize the real possibilities with plasma? I had also sent the photos to hypertherm which for Europe is based in the Netherlands and the response in return was, you will never achieve a result like a laser, you would need a HD plasma, do not dream!!! after that I was very skeptical hence my intensive research which allowed me to arrive on your great forum, finally I will take that as a chance otherwise I would never have discovered it. for the shape of the hole if someone wants to try and share the result, it is in mild steel thickness 16mm, Ø16mm with notch of 7x6mm.
