Plasma Cutting Capabilities
Plasma cutting is a thermal cutting process that uses a jet of ionized gas (plasma) at temperatures up to 30,000°F to melt and sever electrically conductive metals. The plasma arc is created by forcing gas (nitrogen, oxygen, argon, or air) through a narrow nozzle while an electrical arc ionizes the gas. Modern CNC plasma cutting systems with high-definition (HD) plasma torches can produce cut quality approaching laser cutting at lower cost for materials above 0.25" thick. Plasma cutting is the workhorse of structural steel fabrication, heavy equipment manufacturing, and shipbuilding.
±0.015" (±0.4mm) standard; ±0.005" with HD plasma
1-5 business days for cutting; 1-3 weeks for production
$0.50-$30 per part; very economical for thick steel

Plasma Cutting in San Diego — FAQ
How many Plasma Cutting providers are in San Diego, CA?
The San Diego-Chula Vista-Carlsbad metropolitan area has approximately 2,200 manufacturing establishments, many of which offer plasma cutting services. The area employs about 48,000 manufacturing workers, ensuring a skilled workforce for your project.
How thick can plasma cut?
Plasma cutting can sever steel up to 6" thick or more with high-amperage systems. Quality cutting (smooth edges, tight tolerances) is typically achieved on material from 0.25" to 2" thick. For material under 0.25", laser cutting is usually preferred.
What is the difference between plasma and laser cutting?
Laser cutting offers higher precision and better edge quality on thin materials (<0.5"). Plasma cutting is faster and more economical on thick materials (>0.5"), has lower equipment costs, and can cut through surface contaminants. Many shops use both technologies.
What is high-definition plasma cutting?
High-definition (HD) plasma uses a more constricted arc with higher energy density, producing cut quality that approaches laser cutting. HD plasma achieves tolerances of ±0.005" and smooth, nearly dross-free edges on material up to 1" thick.
Can plasma cut aluminum and stainless steel?
Yes, plasma cuts all electrically conductive metals including aluminum, stainless steel, copper, and brass. Different gas mixtures are optimized for each material — nitrogen/hydrogen for stainless, nitrogen for aluminum, oxygen for carbon steel.
