Cutting without a disc · review
The first machine here that publishes its cut thickness for three materials instead of one — which is the whole specification.
Where we come out The cheapest cutter here that tells you what it does on stainless and aluminum, not just on steel.
Three hundred and thirty dollars, 15 to 45 A, and the specification the two cheaper machines on this page omit: cut thickness for three materials.
Fifteen millimeters in ST37 mild steel. Eight in V2A or V4A stainless. Five in aluminum. Those three figures tell you far more than « 50 A » ever could, and the spread between them is not a defect — it is physics. Stainless holds heat in the kerf; aluminum carries it away faster than the arc can put it in. Any machine quoting a single number is quoting the mild steel one.
They are also severance figures in the usual sense: the thickest the machine will get through. Plan on cutting cleanly at roughly two thirds — call this a comfortable 10 mm (0.39 in) machine in steel.
Contactless starting, so painted, coated and rusty surfaces light without scratching for a spot of bare metal. As with every pilot machine, the discipline is not to idle with the arc burning off the work.
The VEVOR pair above cost €173 and €220 and publish their air timings but no thicknesses. This one publishes thicknesses and not its flow timings. Between the two, thickness by material is the number that decides whether the machine suits your work — timings decide how long tips last, which is a running cost rather than a capability.
Cutting current, supply, cut thicknesses, ignition and materials come from the manufacturer’s published specification. No duty cycle is stated there, and none is invented here. Market availability was verified per market on the EAN.

Because plasma cuts by melting metal and blowing it away, and the three behave differently. Stainless conducts heat poorly and holds it in the cut, so the edge oxidizes and the maximum falls. Aluminum conducts heat away so fast that much of the energy leaves the cut zone, which is why the figure is a third of the steel one. A single « cuts up to X mm » number always describes mild steel.
No — buy for about two thirds of it. The quoted figure is the thickest the machine will sever; the thickness it will cut cleanly, quickly and without dross is meaningfully less. A machine rated at 15 mm (0.59 in) is a comfortable 10 mm (0.39 in) machine, and that is the number to compare against your work.
