What plasma cutting covers
Plasma cutting uses an ionized gas (typically air, oxygen, or nitrogen) accelerated through a constricted arc to melt and blow metal — the workhorse process for cutting steel and stainless plate from 0.25" through 6" thick. High-definition (HD) plasma systems produce edges close to laser quality at faster speeds and lower cost on thick material. Common downstream: structural plate parts, heavy-equipment frames, agricultural implement components, and any plate fabrication where laser is too slow or expensive.
What to look for in a supplier
Plasma quality varies dramatically by system: conventional plasma is fast but produces a noticeable bevel and rougher edge; HD plasma is much closer to laser quality. Ask about system class (XPR, MAX-PRO, etc.) and edge-quality expectations. Thickness range: most Ohio plasma shops handle up to 3" mild steel routinely, 6" with the right equipment. Table size matters: 5'×10' is standard, larger tables for big structural work. Bevel-cut capability is important for weld-prep work — confirm if your parts need beveled edges.
FAQ
Common questions
What's the difference between plasma and oxy-fuel cutting?
Oxy-fuel uses a flame and oxygen reaction — slow but cuts very thick steel (>6"). Plasma is much faster on thinner plate, cuts stainless and aluminum (oxy-fuel doesn't), and produces a narrower kerf. For 0.25" through 4" carbon-steel plate, plasma is the workhorse. Above 6", oxy-fuel becomes competitive.
What's the difference between standard and HD plasma?
High-definition (HD) plasma uses a smaller, more constricted arc and gives a near-laser-quality edge with minimal bevel. Standard plasma is faster but produces a more visible bevel (3-5°) and rougher surface. HD costs more per linear foot but reduces or eliminates downstream finishing on weldment parts.
What thicknesses can plasma cut?
Mild steel: up to 6" on high-current systems, routinely 3". Stainless: up to 3". Aluminum: up to 4". Below 0.25", laser is usually faster and produces a better edge.
Why use plasma vs. laser?
Plasma is much faster on thick plate (above 0.5") and dramatically cheaper per linear foot on heavy stock. Laser produces a cleaner edge and tighter tolerance on thin sheet (<0.25"). The crossover thickness is around 0.5" for most shops — below that, laser wins; above that, plasma wins.
