What this machine will and will not work
| Mild steel Production | The production material, and the reason this variant exists. At 65 A the source gives a **quality cut to 16 mm**, a production pierce to 12 mm and a severance cut to 25 mm in mild steel. Working feeds: 3 mm at about 5 000 mm/min, 6 mm at about 3 000 mm/min, 12 mm at about 1 100 mm/min, 16 mm at about 600 mm/min. Below 3 mm, drop to the 45 A fine-cut consumables - 65 A on thin sheet blows a wide, bevelled, dross-heavy kerf and there is no feed that fixes it. Two honest limits: the kerf is about 1.5 mm and the cut carries a 2 to 4 degree bevel on one side, so a plasma part holds about **+/- 0.5 mm** on a profile even though the machine positions to 0.15 mm - and the heat-affected zone means a plasma edge is a fabrication edge, not a bearing surface. Hot-rolled scale is no obstacle to a plasma arc, which is exactly where it beats every mechanical process on this platform. |
|---|---|
| Steel Capable | Stainless and alloy steel cut, with an honest caveat about the edge. On air, at 65 A, stainless cuts cleanly to about 12 mm and severs to about 16 mm, but the edge comes out oxidised and nitrided - a dull grey-brown skin that must be ground back before the joint is welded, or the weld will show porosity. That is a property of cutting stainless with air rather than a fault in the machine; nitrogen or an H35 mix gives a weldable edge and this kit is an air machine. Alloy and tool steels cut and then have to be treated as heat-affected at the edge. Class is 'capable' rather than 'production' for exactly those reasons: it works, and it needs a second operation. |
| Aluminium Capable | Aluminium cuts on air to about 12 mm and severs to about 16 mm, and the result is honestly mediocre: a rough, oxidised edge with heavy dross on the underside that needs grinding, because aluminium's conductivity carries heat away from the kerf faster than the arc puts it in. It is a real capability for bracketry and gusset work and it is not the way to cut a finished part. **One absolute rule: never cut aluminium over water.** Aluminium reacting with water in a cutting table releases hydrogen, hydrogen accumulates under a table, and that is a documented explosion mechanism - which is why this machine is a dry downdraft table by design and carries no water tray at all, as an option or otherwise. |
| Wood Not supported | Not supported, and it is physics rather than policy. A transferred plasma arc needs the workpiece to be part of the electrical circuit: the arc transfers from the electrode to the work and returns through the work clamp. **Wood is an insulator**, so the arc never transfers, the pilot arc simply burns at the nozzle, and what the operator sees is an expensive blowtorch consuming a 600 rupee nozzle while setting fire to a sheet on a downdraft table full of dry residue. Wood on this platform is the S variant, which routes it, or the L variant, which cuts it with light. |
| Plastic Not supported | Not supported, for the same reason as wood: plastics are insulators and the arc will not transfer to them. There is a second and worse reason. The pilot arc that does burn is about 20 000 C, and any plastic under it decomposes rather than cuts - PVC into hydrogen chloride, PTFE into hydrogen fluoride, most others into a mixture nobody has characterised - straight into an extraction system designed for metal oxide. Do not put plastic on this bed, including as backing, packing or masking. |
| Acrylic Not supported | Not supported. Acrylic is an insulator, so the arc does not transfer, and acrylic is also among the most readily ignited materials that gets near a workshop. What a pilot arc does to a sheet of acrylic on a slat bed over a residue tray is start a fire. Acrylic on this platform is the L variant, where a CO2 beam cuts it with a flame-polished edge - which is the single thing that machine does better than anything else in the range. |
