Plasma Cutting vs Laser Cutting - Which Is Better for Your Business?

Choosing the Right Metal Cutting Method for Your Workshop

Choosing the right cutting method is a key decision for any metalworking or fabrication business. Both plasma cutting and laser cutting offer excellent results, but each comes with its own strengths, limitations, and ideal use cases.

What Is Plasma Cutting?

Plasma cutting uses an electrical arc and compressed gas to produce a high-temperature plasma jet that melts and cuts through electrically conductive materials. It’s widely used for cutting mild steel, stainless steel, aluminium, and other metals.

Best for:

• Thick metal cutting

• General fabrication and engineering

• Cost-effective, high-speed production

What Is Laser Cutting?

Laser cutting uses a focused beam of light to melt or vaporise material along a defined path. Fibre lasers are the most common for metal cutting, offering exceptional precision and clean edges.

Best for:

• Thin metals and detailed cuts

• High-precision or decorative work

• Advanced manufacturing and automation

Key Differences Between Plasma and Laser Cutting

Feature	Plasma Cutting	Laser Cutting
Cutting Material	Metals only	Metals, plastics, wood (varies by laser type)
Cutting Thickness	Up to 50mm+	Best for <20mm
Precision	Moderate	Very high
Speed (on thick metals)	Faster	Slower
Operating Costs	Lower	Higher (especially fibre laser)
Maintenance	Low	Moderate
Initial Machine Cost	Lower	Higher
Edge Quality	Rougher	Smoother, minimal post-processing

Which Cutting Method Is Better for Your Business?

Choose Plasma Cutting If:

• You work mainly with thick mild steel or structural metals

• You need fast production with lower operating costs

• You’re in construction, manufacturing, or repair services

Choose Laser Cutting If:

• You require precise, clean cuts with minimal post-processing

• You work with thinner materials or intricate designs

• You’re in aerospace, electronics, signage, or fine metalwork
