With m3 plasma, ESAB defines a new standard for specifying cut quality. You can easily select “Precision”, “Production”, or “Sever” quality modes. The beauty of the m3 system is that you can use more than one quality mode in the same part program. One typical requirement is to maximize cut quality on interior holes and cut-outs, while maximizing cut speed on exterior cuts. Since the PT-36 uses the same electrode for the entire range of oxygen plasma, from 50 to 450 Amps, and nozzles are used at multiple amperage settings, m3 plasma lets you switch quality modes automatically, without changing consumables.
What do Precision, Production, and Sever modes mean? The chart below shows what you can expect in terms of edge quality from each quality mode. Each mode has its purpose, and m3 gives you the flexibility to pick the one you need.
|
| Precision |
Cut results in ISO9013 range 3 or better
Flat cut face
Sharp top & bottom edge
Virtually no dross
|
| Production |
Cut results in ISO9013 range 4 or better
Some rounding
Virtually no dross
|
| Sever |
More edge bevel
Rounded top edge
Some dross

ISO 9013-2002 (E) Specification
The ISO 9013 specification sets international standards for cut edge quality. ESAB m3 plasma Precision Mode blows away the competition - achieving higher cut quality throughout the life of the consumable.
Testing Specification & Methods
So how do you test cut quality of a plasma system? You not only want to know how well it can cut, but how well it will cut over the life of the consumables. So a testing method must measure the cut quality at several points during the life of an electrode and nozzle. The method should also eliminate as many variables as possible, such as variations caused by height control, pierce spatter, part tip-ups, arc stretching, etc. To do this, a test procedure was developed to allow a high number of arc starts and arc-on hours to be accumulated, while periodically measuring a set of cut parts. The resulting data provides a clear indication of achievable cut quality over the life of an electrode, and allows “apples-to-apples” comparisons with competitive plasma systems.
