Buying a Plasma Cutter
The Powermax 30 air has an internal compressor and weighs just south of 14 kilos, making it a highly portable maintenance tool. All you need to start cutting is some power, then plug & play! It has a flexible power input capability, connecting to 110 or 240 volt and you can even run it from a generator.
The Powermax 30 XP is more affordable and still connects to all single phase power, but you will need compressed air capability of 113.3 l/min (4 scfm) at 5.5 bar (80 psi).
Hypertherm's Powermax 45XP is the world's best selling plasma cutter and it's easy to see why. With a change of front end consumables to you can switch between cutting(up to 29mm), gouging and marking. It's light, portable & available in 240 or 415 volts. It can be run on 16 (giving you reduced capacity) or 32 amps and is generator friendly.
