Max-65AL Non-HF (Low Frequency) Air Plasma Cutter

Non-HF Plasma Cutting Machine

The Max-65AL is a non-high-frequency (low-frequency arc starting) air plasma cutting machine designed for both handheld cutting and automated operation on CNC tables and robot cells. Digital communication and analogue interfaces are provided as standard, so it integrates with most automation equipment without additional converters. Because arc starting does not rely on high frequency, the unit generates negligible electromagnetic interference. It can be installed directly alongside CNC controllers, servo drives and communication equipment without the shielding measures that HF-start machines require. The low-frequency torch and concentrated arc start give a stable, repeatable pierce and protect consumables during frequent starts. A fine, well-columnated arc produces a narrow kerf with a small bevel angle and a thin heat-affected zone, which keeps thin sheet flat and reduces secondary grinding. Current is set accurately and steplessly, and the control monitors gas pressure continuously, with automatic protection against over-temperature, under-voltage and phase loss. The result is a compact, industrial-duty source for carbon steel, alloy steel and non-ferrous metals across sheet metal, structural fabrication and maintenance work.

Low-frequency (non-HF) arc starting, very low EMI, safe next to CNC and communication equipment
Fine plasma arc column with narrow kerf, small bevel and thin heat-affected zone
High-precision torch concentricity and swirl gas path for repeatable cut faces
Digital and analogue interfaces for CNC tables and robot cells
Gas-pressure monitoring with automatic over-temperature, under-voltage and phase-loss protection
Stepless current preset for accurate matching to plate thickness
65 A class output covering thin to medium plate in one machine

Typical Applications

Sheet-metal fabrication and general metal products
Machine frames, panels and structural components
Stainless-steel fabrications and food machinery
Maintenance, repair and site installation work
CNC cutting tables requiring interference-free arc starting

Selection & Setup Notes

The Max-65AL sits between the 45 A thin-sheet model and the 105 A general-purpose model in the precision plasma range. Choose it when most of your work falls between 3 mm and 12 mm and you want a single machine for both handheld and machine cutting. For thinner, appearance-critical parts see the Max-45AL; for heavier plate and gouging see the Max-105AL.
