The Hypertherm Powermax 65 is an inverter plasma cutter for hand cutting, run from a three phase 400 V supply. You set the output current from 20 to 65 A, and at the full 65 A the machine works at a 50% duty cycle at a temperature of 40 degrees C. The set holds a Duramax 75 degree hand torch.
What this machine is for
This is the version with analogue operation, without menus and screens, in which the whole process comes down to setting the current and picking the nozzles. The maker gives a quality cut of steel 20 mm thick at a speed of 500 mm/min and piercing of mild steel up to 16 mm. An open circuit voltage of 270 V direct current gives a fast and sure start of the arc, without wearing the electrode out at every strike.
The Boost Conditioner circuit compensates supply voltage swings, the documentation gives a tolerance down to minus 15 percent for a 400 V mains. That matters when you work from a long extension lead, on a building site and on a supply from an installation with weaker parameters, because the arc current stays stable and the cut edge repeatable. The maker pointed this model to repair workshops and maintenance, to small and medium production plants as a tool for hand cutting and to mobile services in the field.
Features and equipment
- Inverter power block with a 50% duty cycle at 65 A: at full current half the time goes to cutting and half to cooling.
- Boost Conditioner: the circuit evens out supply voltage drops down to minus 15 percent at 400 V, so the arc holds its parameters also in a weak mains.
- Open circuit voltage 270 V direct current: the arc strikes at once, without repeated tries.
- Duramax 75 degree hand torch with a Conical Flow nozzle: a higher energy density of the arc gives a narrower kerf and less dross on the lower edge.
- Four part set of consumables: you pick the components separately, for example FineCut nozzles for thin sheet.
- Fail-safe arc with a sprung electrode: the torch takes accidental contact with the material without damage.
- Wind Tunnel Technology: the cooling air goes around the electronic assemblies, so dust and filings do not settle on the boards.

What to watch out for
The supply is 400 V in three phases, at 50 or 60 Hz, and the draw is 15.5 A at a power of 9.3 kW, so size the circuit with a margin. The plasma works on compressed air, you need a sound compressor with a dryer and a filter, because damp and oil destroy the nozzles faster than the current itself. The consumables of the torch are matched to the cutting current and to the material thickness, and you check their state before work. The 50% duty cycle at 65 A has to be planned into the schedule, on longer cuts you go down with the current or take breaks.
