Hypertherm Powermax105

The Hypertherm Powermax105 is a 105 A air plasma system that runs either a hand torch or a machine torch for CNC tables. Hypertherm lists a 30–105 A output, a recommended cut capacity of 32 mm (1-1/4 in) at 500 mm/min (20 ipm), and a severance capacity of 50 mm (2 in) at 125 mm/min (5 ipm). The CSA model takes 200–600 V three-phase power at 50/60 Hz and senses the supply voltage itself.

For table work the pierce capacity matters more than the headline figure. It is 22 mm (7/8 in), so plate between 22 mm and the 32 mm recommended capacity can be cut but has to be started from an edge. Nested parts with internal cut-outs should be planned around 22 mm, not 32 mm. Stainless steel and aluminum are each listed at 25 mm (1 in) recommended.

Duty cycle is 80% at 105 A. With a hand torch that is rarely a constraint. A CNC table cutting long nests at the full 105 A has to allow for arc-off time, and the table gives no duty cycle for lower currents.

The power supply measures 592 mm deep, 274 mm wide and 508 mm high (23.3 × 10.8 × 20.0 in). Weight depends on the electrical variant: 45 kg (100 lbs) for the 200–600 V CSA and 230–400 V CE models, and 41 kg (90.4 lbs) for the 380 V CCC and 400 V CE models. That is slightly lighter than the Powermax125, which weighs 47.9 kg (105.7 lbs) in its 480 V form. The unit cuts with clean, dry, oil-free air or nitrogen, and an engine drive must supply 30 kW for full 105 A output.
