Max-300HPR High-Performance Plasma Cutting System

Precision Plasma Cutter

The Max-300HPR extends the high-performance precision plasma platform to 300 A, supplied with a gas console for air, oxygen and nitrogen. Current ripple control technology keeps output ripple low, which stabilises cut quality and produces smooth faces. The professionally tuned torch cooling system — combining a high-flow, high-head water pump with a high-capacity heat-dissipation structure — significantly extends the life of torch consumables. Multiple gas inlet connections support different cutting processes and deliver high-quality faces across all common metals. Excellent high-frequency arc-start control, with the HF box structurally separated from the power source, reduces high-frequency interference with the CNC system as far as possible, while the short torch cable guarantees a 100% arc-start success rate. Comprehensive communication and control interfaces make functional expansion straightforward and simplify integration with intelligent CNC systems. Applications Carbon steel, stainless steel, aluminium and copper, in industrial power-plant installation, boilers and pressure vessels, shipbuilding, metallurgy, petrochemicals, aerospace, construction machinery and steel-structure fabrication, and throughout industries involving metal cutting.

Closed-loop gas pressure and flow control for consistent batches
Current ripple control for stable output and smooth faces
Separated HF box and short torch cable: 100% arc-start success, minimal CNC interference
High-capacity torch cooling for long consumable life at high duty

Typical Applications

Medium and heavy plate where weld-ready edges are required
Pressure vessels, boilers and heavy steel fabrication
Stainless-steel and aluminium processing at production volume
Shipbuilding and offshore fabrication
Automated lines running multi-shift production

Selection & Setup Notes

Choose the Max-300HPR when plate thickness and edge quality both matter: it holds oxygen-cut quality on carbon steel well past the range of a 200 A system. Match it with the MSW-20L water chiller for continuous duty. For lighter work see the Max-200HPR; for the top of the range, the Max-400HPR.

Standards & Further Reading

External reference: ISO 9013 — Thermal cutting classification — ISO 9013 defines the quality classes for thermal cut surfaces (perpendicularity, bevel, dross).

Frequently Asked Questions

How does the 300HPR differ from the 200HPR?

Mainly in current class and sustained heavy-duty capability. Shops with more medium-heavy plate and longer shifts suit the 300HPR.

What compressor and gas capacity do I need?
