Overview

The Hypertherm Powermax65 is a 65 A air plasma system whose CSA model accepts a wide spread of shop supplies: 200–480 V single-phase or 200–600 V three-phase, at 50/60 Hz. Output is adjustable from 20–65 A, the recommended cut capacity is 20 mm (3/4 in) at 500 mm/min (20 ipm), and the unit weighs 29 kg (64 lbs).

Input voltage does more than decide whether the unit can be connected. Hypertherm rates the duty cycle at 50% at 65 A on 230–600 V, but 40% at 65 A on 200–208 V. A shop on a 208 V service gets less arc-on time at full output than one on 480 V. Backing the current off to 46 A brings the rating to 100% on 230–600 V, which is the setting to aim for on long mechanized cuts in thinner plate.

Three thickness figures describe the cutting range. Pierce capacity is 16 mm (5/8 in), the limit for parts that start inside the plate. Recommended capacity is 20 mm (3/4 in), and stainless steel and aluminum are listed at that same thickness. Severance capacity is 32 mm (1-1/4 in), reached at 125 mm/min (5 ipm), a quarter of the speed quoted for the recommended cut.

In weight it falls between two siblings: 29 kg (64 lbs) against 14 kg (31 lbs) for the Powermax45 XP and 45 kg (100 lbs) for the 200–600 V CSA Powermax105. The case measures 500 mm (19.7 in) deep, 234 mm (9.2 in) wide and 455 mm (17.9 in) high. It cuts with clean, dry, oil-free air or nitrogen.

Strengths & Limitations

Strengths

CSA model runs on 200–480 V single-phase or 200–600 V three-phase input
100% duty cycle at 46 A on 230–600 V
Recommended cut capacity of 20 mm (3/4 in) at 500 mm/min (20 ipm), the same thickness listed for stainless steel and aluminum
Pierce capacity of 16 mm (5/8 in), close to the 20 mm (3/4 in) recommended capacity
29 kg (64 lbs) in a case 500 mm (19.7 in) deep, 234 mm (9.2 in) wide and 455 mm (17.9 in) high

Limitations

Duty cycle at 65 A falls to 40% on a 200–208 V supply
Even on 230–600 V the duty cycle at the full 65 A is 50%
Severance capacity of 32 mm (1-1/4 in) is reached at 125 mm/min (5 ipm)
Plate above the 16 mm (5/8 in) pierce capacity needs an edge start on a CNC table

Best For

Shops that may move the unit between single-phase and three-phase supplies CNC table work in plate up to the 16 mm (5/8 in) pierce capacity Stainless steel and aluminum up to 20 mm (3/4 in) Long cuts at 46 A, where the duty cycle is 100% on 230–600 V

Frequently Asked Questions

01 Can the Powermax65 run on single-phase power?

Yes. The CSA input row lists 200–480 V single-phase and 200–600 V three-phase, both at 50/60 Hz. The duty cycle row treats single-phase and three-phase alike and separates the figures by voltage instead.

02 How does input voltage affect the Powermax65 duty cycle?

At the full 65 A the duty cycle is 50% on 230–600 V and 40% on 200–208 V. At 46 A it is 100% on 230–600 V. No 100% figure is given for a 200–208 V supply, so a shop on that voltage should plan around the 40% rating at full output.

03 How thick can the Powermax65 cut and pierce?

Recommended cut capacity is 20 mm (3/4 in) at 500 mm/min (20 ipm), and stainless steel and aluminum are listed at 20 mm (3/4 in) as well. Pierce capacity is 16 mm (5/8 in). Severance capacity is 32 mm (1-1/4 in) at 125 mm/min (5 ipm).

04 How does the Powermax65 compare in weight with the Powermax45 XP and Powermax105?

The Powermax65 weighs 29 kg (64 lbs). The Powermax45 XP is 14 kg (31 lbs), and the Powermax105 is 45 kg (100 lbs) in its 200–600 V CSA version. The Powermax65 is the middle of the three by a wide margin either way.

05 What gas does the Powermax65 need?

Clean, dry, oil-free air or nitrogen. The words clean, dry and oil-free are part of the requirement, so the compressor line needs filtration and drying to suit. The table does not give a flow or pressure figure; take those from the operator manual.
